ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Nature of Operations
	Our Company, a Delaware corporation, provides ready-mixed concrete, aggregates and concrete-related products and services to the construction industry in several major markets in the United States. U.S. Concrete, Inc. is a holding company and conducts its businesses through its consolidated subsidiaries.  In these notes to consolidated financial statements (these "Notes"), we refer to U.S. Concrete, Inc. and its subsidiaries as "we," "us," the "Company," or "U.S. Concrete" unless we specifically state otherwise or the context indicates otherwise.
	Basis of Presentation
	The consolidated financial statements consist of the accounts of U.S. Concrete, Inc. and its wholly owned subsidiaries. All significant intercompany account balances and transactions have been eliminated.
	On August 20, 2012, we completed the sale of substantially all of our California precast operations to Oldcastle Precast, Inc. ("Oldcastle") (see Note 2). The results of operations for these units have been included in discontinued operations for the periods presented.
	On September 14, 2012, we purchased four ready-mixed concrete plants and related assets and inventory from Colorado River Concrete L.P., Cindy & Robin Concrete, L.P. and E&R Artecona Family Limited Partnership (collectively, "CRC") (see Note 2). Accordingly, all of the assets acquired were recorded at their respective fair values as of the date of the acquisition, and the results of operations are included in the consolidated financial statements from the date of acquisition.
	On October 30, 2012, we completed the acquisition of all the outstanding equity interests of Bode Gravel Co., a California subchapter S corporation ("Bode Gravel"), and Bode Concrete LLC, a California limited liability company ("Bode Concrete" and, together with Bode Gravel, the "Bode Companies"), pursuant to an equity purchase agreement (see Note 2). Accordingly, all of the assets acquired and liabilities assumed were recorded at their respective fair values as of the date of the acquisition, and the results of operations are included in the consolidated financial statements from the date of acquisition.
	On December 17, 2012, we completed the sale of substantially all of our assets associated with our Smith Precast operations ("Smith") located in Phoenix, Arizona, to Jensen Enterprises, Inc. ("Jensen") (see Note 2). The results of operations for this unit have been included in discontinued operations for the periods presented.
	On July 26, 2013, we acquired three ready-mixed concrete plants and related assets in our north Texas market from Bodin Concrete, L.P. ("Bodin") (see Note 2). Accordingly, all of the assets acquired were recorded at their respective fair values as of the date of the acquisition, and the results of operations are included in the consolidated financial statements from the date of acquisition.
	Cash and Cash Equivalents
	We record as cash equivalents all highly liquid investments having maturities of three months or less at the date of purchase. Our cash equivalents may include money market accounts, certificates of deposit and commercial paper of highly rated corporate or government issuers. We classify our cash equivalents as held-to-maturity. Cash equivalents are stated at cost plus accrued interest, which approximates market value. The maximum amount placed in any one financial institution is limited in order to reduce risk. At times, our investments may be in excess of amounts insured by the Federal Deposit Insurance Corporation ("FDIC"). We have not experienced any losses on these accounts. Cash held as collateral or escrowed for contingent liabilities is included in other current and noncurrent assets based on the expected release date of the underlying obligation.
	Inventories
	Inventories consist primarily of cement and other raw materials, aggregates at our pits and quarries, precast concrete products and building materials that we hold for sale or use in the ordinary course of business. Inventories are stated at the lower of cost or fair market value using the average cost and first-in, first-out methods. We reduce the carrying value of our inventories for estimated excess and obsolete inventories equal to the difference between the cost of inventory and its estimated realizable value based upon assumptions about future product demand and market conditions. Once the new cost basis is established, the value is not increased with any changes in circumstances that would indicate an increase after the remeasurement. If actual product demand or market conditions are less favorable than those projected by management, inventory write-downs may be required that could result in a material change to our consolidated results of operations or financial position.
	Prepaid Expenses
	Prepaid expenses primarily include amounts we have paid for insurance, licenses, taxes, rent and maintenance contracts. We expense or amortize all prepaid amounts as used or over the period of benefit, as applicable.
	Property, Plant and Equipment, Net
	We state property, plant and equipment at cost and use the straight-line method to compute depreciation of these assets other than mineral deposits over the following estimated useful lives: buildings and land improvements, from 10 to 40 years; machinery and equipment, from 10 to 30 years; mixers, trucks and other vehicles, from one to 12 years; and other, from three to 10 years. We capitalize leasehold improvements on properties held under operating leases and amortize those costs over the lesser of their estimated useful lives or the applicable lease term.  We compute depletion of mineral deposits as such deposits are extracted utilizing the units-of-production method. We expense maintenance and repair costs when incurred and capitalize and depreciate expenditures for major renewals and betterments that extend the useful lives of our existing assets.  When we retire or dispose of property, plant or equipment, we remove the related cost and accumulated depreciation from our accounts and reflect any resulting gain or loss in our statements of operations.
	Impairment of Long-lived assets
	We evaluate the recoverability of our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets is measured by comparing the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. Such evaluations for impairment are significantly impacted by estimates of future prices for our products, capital needs, economic trends in the applicable construction sector and other factors.  If we consider such assets to be impaired, the impairment we recognize is measured by the amount by which the carrying amount of the assets exceeds their fair value.  Assets to be disposed of by sale are reflected at the lower of their carrying amounts, or fair values, less cost to sell. We test for impairment using a multi-tiered approach that incorporates an equal weighting to a multiple of earnings and an equal weighting to discounted estimated future cash flows.
	Intangible Assets Including Goodwill
	Identifiable intangible assets with finite lives are amortized over their estimated useful lives. They are amortized using a straight-line approach based on the estimated useful life of each asset. Goodwill represents the amount by which the total purchase price we have paid for acquisitions exceeds our estimated fair value of the net tangible and identifiable intangible assets acquired.  Goodwill is not amortized, but is evaluated for impairment within the reporting unit on an annual basis. We generally test for intangible asset impairment in the fourth quarter of each year, because this period gives us the best visibility of the reporting units’ operating performances for the current year (seasonally, April through October are our highest revenue and production months), and our outlook for the upcoming year, since much of our customer base is finalizing operating and capital budgets during the fourth quarter.  The impairment test we use involves estimating the fair value of our reporting units and comparing the result to the reporting unit's carrying value. We estimate fair value using an equally weighted combination of discounted cash flows and multiples of revenue and EBITDA. The discounted cash flow model includes forecasts for revenue and cash flows discounted at our weighted average cost of capital. Multiples of revenue and EBITDA are calculated using the trailing twelve months results compared to the enterprise value of the Company, which is determined based on the combination of the market value of our capital stock and total outstanding debt. If the fair value exceeds the carrying value, the second step is not performed and no impairment is recorded. If however, the fair value is below the carrying value, a second step is performed to calculate the amount of the impairment by measuring the goodwill at an implied fair value. See Note 4 for further discussion of our goodwill and purchased intangible assets.
	Debt Issue Costs
	We amortize debt issue costs related to our $125.0 million asset-based revolving credit facility (the "2013 Loan Agreement"), our 8.5% Senior Secured Notes due 2018 (the "2018 Notes"), our 9.5% Senior Secured Notes due 2015 (the "2013 Notes"), and our 9.5% Convertible Secured Notes due 2015 (the "Convertible Notes") as interest expense over the scheduled maturity period of the debt. Unamortized debt issuance costs were $7.6 million and $4.2 million as of December 31, 2013 and 2012, respectively. We include unamortized debt issue costs in other assets. See Note 9 for additional information regarding our debt, and Note 10 regarding our extinguishment of debt during 2013 and 2012.
	Allowance for Doubtful Accounts
	We maintain an allowance for accounts receivable we believe may not be collected in full. A provision for bad debt expense recorded to selling, general and administrative expenses increases the allowance.  Accounts receivable are written off when we determine the receivable will not be collected.  Accounts receivable that we write off our books decrease the allowance.  We determine the amount of bad debt expense we record each period and the resulting adequacy of the allowance at the end of each period by using a combination of historical loss experience, a customer-by-customer analysis of our accounts receivable balances each period and subjective assessments of our bad debt exposure.
	Revenue and Expenses
	We derive substantially all of our revenue from the production and delivery of ready-mixed concrete, aggregates, precast concrete products, and related building materials.  We recognize revenue, net of sales tax, when products are delivered, selling price is fixed or determinable, persuasive evidence of an arrangement exists, and collection is reasonably assured.  Amounts billed to customers for delivery costs are classified as a component of total revenues and the related delivery costs (excluding depreciation) are classified as a component of total cost of goods sold. Cost of goods sold consists primarily of product costs and operating expenses (excluding depreciation, depletion and amortization).  Operating expenses consist primarily of wages, benefits, insurance and other expenses attributable to plant operations, repairs and maintenance, and delivery costs.  Selling expenses consist primarily of sales commissions, salaries of sales managers, travel and entertainment expenses, and trade show expenses. General and administrative expenses consist primarily of executive and administrative compensation and benefits, office rent, utilities, communication and technology expenses, provision for doubtful accounts, and legal and professional fees.
	Deferred Rent
	We recognize escalating lease payments on a straight-line basis over the term of each respective lease with the difference between cash payment and rent expense recognized being recorded as deferred rent (included in accrued liabilities) in the accompanying consolidated balance sheets.
	Insurance Programs
	We maintain third-party insurance coverage against certain risks. Under our insurance programs, we share the risk of loss with our insurance underwriters by maintaining high deductibles subject to aggregate annual loss limitations.  In connection with these automobile, general liability and workers’ compensation insurance programs, we have entered into standby letters of credit agreements totaling $11.3 million and $12.2 million at December 31, 2013 and 2012, respectively.  We fund our deductibles and record an expense for losses we expect under the programs.  We determine expected losses using a combination of our historical loss experience and subjective assessments of our future loss exposure.  The estimated losses are subject to uncertainty from various sources, including changes in claim reporting patterns, claim settlement patterns, judicial decisions, legislation and economic conditions.  The amounts accrued for self-insured claims were $8.6 million and $9.0 million as of December 31, 2013 and 2012, respectively.  We include these accruals in accrued liabilities.
	Income Taxes
	We use the liability method of accounting for income taxes. Under this method, we record deferred income taxes based on temporary differences between the financial reporting and tax bases of assets and liabilities and use enacted tax rates and laws that we expect will be in effect when we recover those assets or settle those liabilities, as the case may be, to measure those taxes.  We record a valuation allowance to reduce the deferred tax assets to the amount that is more likely than not to be realized.  We have a valuation allowance of $44.4 million and $44.9 million as of December 31, 2013 and 2012, respectively.
	Fair Value of Financial Instruments
	Our financial instruments consist of cash and cash equivalents, trade receivables, trade payables, long-term debt, other long-term obligations, and derivative liabilities.  We consider the carrying values of cash and cash equivalents, trade receivables and trade payables to be representative of their respective fair values because of their short-term maturities or expected settlement dates.  The fair value of our 2018 Notes, estimated based on broker/dealer quoted market prices, was $204.5 million as of December 31, 2013. The carrying value of outstanding amounts under our Revolving Facility (as defined herein) approximates fair value due to the floating interest rate. The fair value of our Convertible Notes was $0.1 million and $68.8 million at December 31, 2013 and 2012, respectively, and the fair value of the embedded derivative in our Convertible Notes that was bifurcated and separately valued was zero and $17.2 million at December 31, 2013 and 2012, respectively. The fair value of issued Warrants (as defined herein) was $21.7 million and $4.9 million at December 31, 2013 and 2012, respectively. The fair value of the Bode Earn-out (as defined herein) associated with the acquisition of the Bode Companies was $7.0 million at both December 31, 2013 and 2012. See Note 11 to our consolidated financial statements for further information regarding our derivative liabilities, Note 12 regarding our other long-term obligations, and Note 13 regarding our fair value disclosures.
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  Estimates and assumptions that we consider significant in the preparation of our financial statements include those related to our allowance for doubtful accounts, goodwill, intangibles, valuation of derivatives, accruals for self-insurance, income taxes, the valuation of inventory and the valuation and useful lives of property, plant and equipment.
	Stripping Costs
	We include post-production stripping costs in the cost of inventory produced during the period as these costs are incurred. Post-production stripping costs represent stripping costs incurred after the first salable minerals are extracted from the mine.
	Loss Per Share
	Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period after giving effect to all potentially dilutive securities outstanding during the period. See Note 19 for additional information regarding our earnings (loss) per share.
	Comprehensive Income
	Comprehensive income represents all changes in equity of an entity during the reporting period, except those resulting from investments by and distributions to stockholders. For the years ended December 31, 2013 and December 31, 2012, no differences existed between our consolidated net income and our consolidated comprehensive income.
	Stock-based Compensation
	Stock-based employee compensation cost is measured at the grant date based on the calculated fair value of the award. We recognize expense over the employee’s requisite service period, generally the vesting period of the award, or in the case of performance-based awards, over the life of the derived service period. The related excess tax benefit received upon exercise of stock options or vesting of restricted stock, if any, is reflected in the statement of cash flows as a financing activity rather than an operating activity. See Note 18 for additional information regarding our stock-based compensation plans.
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (the "FASB") issued an amendment on the financial statement presentation for an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendment specifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward with certain exceptions. The guidance is effective for annual and interim reporting periods beginning after December 15, 2013. The Company's existing policies and procedures comply with the guidance, thus there will be no material impact on the consolidated financial statements upon the guidance becoming effective.
	In January 2013, the FASB issued an amendment to clarify the scope of a prior amendment issued in December 2011. The January 2013 amendment limits the December 2011 amendment's disclosure requirements regarding offsetting and related arrangements to specific derivative, borrowing, and lending transactions. Thus, certain master netting arrangements are no longer subject to the December 2011 amendment's requirements. Both the December 2011 and January 2013 amendments are effective for annual and interim reporting periods beginning on or after January 1, 2013. The Company adopted this guidance on January 1, 2013, and there was no material impact on the consolidated financial statements.
	In July 2012, the FASB issued an amendment to its indefinite-lived intangible assets impairment testing guidance to simplify how entities test for indefinite-lived intangible asset impairments. The objective of the amendment is to reduce cost and complexity by providing an entity with the option to make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test. The amendment also enhances the consistency of impairment testing guidance among long-lived asset categories by permitting an entity to assess qualitative factors to determine whether it is necessary to calculate the asset's fair value when testing an indefinite-lived intangible asset for impairment, which is equivalent to the impairment testing requirements for other long-lived assets. The amendment is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, although early adoption is permitted. The Company adopted this guidance on January 1, 2013, and there was no material impact on the consolidated financial statements. The Company completes annual impairment testing during the fourth quarter.

	On July 26, 2013, we acquired three ready-mixed concrete plants and related assets in our north Texas market from Bodin for $4.4 million in cash. We acquired plant and equipment valued at $3.3 million, and recognized goodwill of $1.1 million. The goodwill ascribed to the purchase is related to the synergies we expect to achieve with expansion into the eastern corridor of the north Texas market in which we already operate. We expect the goodwill to be deductible for tax purposes. See Note 17 for additional information regarding income taxes.
	Sale of Smith Precast Operations
	On December 17, 2012, we completed the sale of substantially all of our assets associated with Smith located in Phoenix, Arizona, to Jensen for $4.3 million in cash and the assumption of certain obligations. The assets purchased by Jensen included certain facilities, fixed assets, and working capital items. In addition, Jensen assumed the obligations of a capital lease previously held by Smith. The results of operations for this unit have been included in discontinued operations for the periods presented.
	During the third quarter of 2013, pursuant to the terms of the asset purchase agreement, we made payments totaling $0.5 million to Jensen related to the reacquisition of certain uncollected receivables as well as the settlement of certain accrued liabilities.
	Purchase of Bode Gravel and Bode Concrete Equity Interests
	On October 30, 2012, we completed the acquisition of all of the outstanding equity interests of the Bode Companies pursuant to an equity purchase agreement dated October 17, 2012. The Bode Companies operated two fixed and one portable ready-mixed concrete plant and 41 mixer trucks in the San Francisco, California area. The purchase price for the acquisition was $24.5 million in cash, plus working capital and closing adjustments of $1.6 million, plus potential earn-out payments (the "Bode Earn-out"). The earn-out payments are contingent upon reaching negotiated volume hurdles, with an aggregate present value of up to $7.0 million in cash payable over a 6-year period, resulting in total consideration fair value of $33.1 million. We funded the acquisition from cash on hand and borrowings under our 2012 Credit Agreement (as defined in Note 9). In March 2013, we completed our final working capital adjustments with the former equity owners, resulting in a reduction in goodwill of $0.2 million.
	The assets acquired and liabilities assumed at the acquisition date based upon their respective fair values are summarized below (in thousands):
		Bode Companies
		30-Oct-12
	Accounts receivable	$	7,194
	Inventory	156
	Property, plant and equipment	9,284
	Customer relationships	13,500
	Trade name	1,300
	Backlog	800
	Other assets	245
	Assets acquired	$	32,479
	Accounts payable	2,920
	Accrued expenses	1,329
	Deferred tax liability	3,385
	Bode Earn-out	7,000
	Liabilities assumed	$	14,634
	Goodwill	8,254
	Net assets acquired	$	26,099
	The excess of the purchase price over the fair values of the assets acquired and liabilities assumed represents the goodwill resulting from the acquisition. The goodwill ascribed to the purchase is related to the synergies we expected to achieve and have achieved, as well as expansion of our business in the San Francisco, California area in which we already operate. We expect a portion of the goodwill to be deductible for tax purposes. See Note 4 for additional information regarding the goodwill and finite-lived intangible assets. See Note 12 for additional information regarding the Bode Earn-out. See Note 17 for additional information regarding income taxes. The final purchase price allocation was completed by October 30, 2013, one year after the acquisition date, and did not change materially from amounts shown above.
	The following unaudited pro forma information presents the combined financial results for the year ended December 31, 2012 as if the acquisition had occurred on January 1, 2012, (in thousands, except per share information):
		For the year ended December 31,
		(unaudited)
		2012
	Revenue from continuing operations	$	563,706
	Net loss	$	(23,966	)
	Loss per share, basic and diluted	$	(1.96	)
	The above pro forma results were prepared based on the historical GAAP results of the Company and the Bode Companies, and are not necessarily indicative of what the Company's actual results would have been had the transaction occurred on January 1, 2012. The unaudited pro forma net loss and net loss per share amounts above reflect an adjustment for inclusion of an additional $0.9 million in amortization of intangibles for the year ended December 31, 2012; exclusion of $0.6 million for severance and related costs for former employees of the Bode Companies; and exclusion of $0.3 million of legal costs incurred by the Company in 2012 related to the acquisition. The unaudited pro forma results do not reflect any operational efficiencies or potential cost savings that may occur as a result of consolidation of the operations.
	Purchase of Colorado River Concrete Assets
	On September 14, 2012, we purchased four ready-mixed concrete plants and related assets and inventory from CRC in our west Texas market for $2.4 million in cash and a $1.9 million promissory note at a fixed annual interest rate of 4.5%. This note is being paid in twenty-four equal monthly installments which began in January 2013. We made cash payments on the promissory note of approximately $0.9 million during the year ended December 31, 2013. The purchase of these assets allowed us to expand our business in two of our major markets; west Texas and north Texas. We acquired plant and equipment valued at $3.2 million, inventory valued at $0.2 million, and recognized goodwill valued at $1.0 million. No liabilities were assumed in the purchase. The goodwill ascribed to the purchase is related to the synergies we expected to and have achieved with expansion of these areas in which we already operate. We expect the goodwill to be deductible for tax purposes.
	Sale of California Precast Operations
	On August 2, 2012, we executed a definitive asset purchase agreement to sell substantially all of our California precast operations to Oldcastle for $21.3 million in cash, plus net working capital adjustments. The assets purchased by Oldcastle included certain facilities, fixed assets, and working capital items. The results of operations for these units have been included in discontinued operations for the periods presented.
	In conjunction with the Oldcastle agreement, we also entered into certain sublease and license agreements with Oldcastle for certain land and property that is leased or owned by us. As the sublease and license agreements provide payment for the full amount of our obligation under the leases, we did not record any liability for exit obligations associated with these agreements.
	During the first quarter of 2013, pursuant to the terms of the asset purchase agreement, we made payments totaling $1.9 million to Oldcastle related to the reacquisition of certain uncollected receivables as well as the settlement of certain accrued liabilities. At December 31, 2013, $0.2 million of the acquired receivables are recorded in other receivables on our consolidated balance sheet.
	Other
	In October 2006, we acquired certain aggregates assets located in New Jersey. As a condition of the purchase agreement, additional consideration would be due if we were able to receive permits that allowed us to mine the minerals from certain areas. In April 2012, we obtained the permits necessary to allow us to mine this area of property. Accordingly, we accrued $1.4 million in additional purchase consideration during the quarter ended June 30, 2012. On October 5, 2012, we signed an agreement with the seller to pay a total of $1.0 million in lieu of the $1.4 million contractual payment due to a lower volume of aggregate assets available to mine than originally contemplated in the agreement. We signed a promissory note for the $1.0 million settlement, payable in eight equal quarterly installments which began in November 2012 at a fixed annual interest rate of 2.5%. We made cash payments on the promissory notes of approximately $0.5 million and $0.1 million during the years ended December 31, 2013 and 2012.
	During the third quarter of 2012, we made the decision to sell certain of our land and buildings in northern California and classified these assets as held for sale. These assets were recorded at the estimated fair value less costs to sell, which approximated net book value of $2.6 million. This transaction closed during the fourth quarter of 2012 and we received $3.2 million in proceeds. Accordingly, we recorded a gain on sale of assets of $0.6 million, which is included in our statement of operations for the year ended December 31, 2012.
	In October 2010, we acquired three ready-mixed concrete plants and related assets in our west Texas market for approximately $3.0 million, plus the value of the inventory on hand at closing. We made cash payments of $0.4 million at closing and issued a promissory note for the remaining $2.6 million at a fixed annual interest rate of 5.0%. We made cash payments on this note of approximately $0.4 million during each of the years ended December 31, 2013 and 2012.
	In August 2010, we entered into a redemption agreement to have our 60% interest in our Michigan subsidiary, Superior Materials Holdings, LLC ("Superior") redeemed by Superior. At the closing of the redemption on September 30, 2010, we and certain of our subsidiaries paid $0.6 million in cash and issued a $1.5 million promissory note to Superior as partial consideration for certain indemnifications and other consideration provided by the minority owner and their new joint venture partner pursuant to the redemption agreement. In January 2012, we paid $0.8 million to complete payment of the promissory note.
	The pro forma impacts of our 2013 and 2012 acquisitions, excluding the Bode Companies, have not been included as they were immaterial to our financial statements individually and in the aggregate.

	GOODWILL AND INTANGIBLE ASSETS, NET
	Goodwill
	We record as goodwill the amount by which the total purchase price we pay in our acquisition transactions exceeds our estimated fair value of the identifiable net assets we acquire. We test goodwill for impairment on an annual basis, or more often if events or circumstances indicate that there may be impairment.  We generally test for goodwill impairment in the fourth quarter of each year, because this period gives us the best visibility of the reporting units’ operating performances for the current year (seasonally, April through October are our highest revenue and production months) and our outlook for the upcoming year, since much of our customer base is finalizing operating and capital budgets during the fourth quarter.  The impairment test we use involves estimating the fair value of our reporting units and comparing the result to the reporting unit's carrying value. We estimate fair value using an equally weighted combination of discounted cash flows and multiples of revenue and EBITDA. The discounted cash flow model includes forecasts for revenue and cash flows discounted at our weighted average cost of capital. Multiples of revenue and EBITDA are calculated using the trailing twelve months results compared to the enterprise value of the Company, which is determined based on the combination of the market value of our capital stock and total outstanding debt.
	We acquired three ready-mixed concrete plants during October 2010 and four ready-mixed concrete plants in September 2012 which resulted in the recording of approximately $1.5 million and $1.0 million of goodwill, respectively, for our north Texas and west Texas operations. We acquired two ready-mixed concrete plants, one portable plant, and 41 mixer trucks in the San Francisco area during October 2012 which resulted in the recording of approximately $8.2 million of goodwill for our California operations. In 2013, we completed final working capital adjustments related to the San Francisco acquisition which resulted in a $0.2 million reduction of goodwill. We acquired three ready-mixed concrete plants in our north Texas operations during July 2013 which resulted in the recording of approximately $1.1 million of goodwill. We completed our annual assessment of impairment during the fourth quarter of 2013, and there was no impairment to any of our operations with goodwill.
	All goodwill relates to our ready-mixed concrete reportable segment. The change in goodwill from January 1, 2012 to December 31, 2013 is as follows (in thousands):

	Senior Secured Notes due 2018
	On November 22, 2013, we completed an offering of $200.0 million aggregate principal amount of 8.5% senior secured notes due 2018 at an offering price of 100%. We used a portion of the net proceeds from the 2018 Notes to repay all of our outstanding borrowings under the Revolving Facility and to redeem all of our outstanding 2013 Notes. The issuance of the 2018 Notes and redemption of the 2013 Notes qualified as a Senior Notes Refinancing (as defined below), under the terms of the 2013 Loan Agreement.
	The Notes are governed by an indenture (the “Indenture”) dated as of November 22, 2013, by and among us and U.S. Bank National Association, as trustee and noteholder collateral agent (the “Notes Collateral Agent”). We are obligated to pay interest on the 2018 Notes on June 1 and December 1 of each year, commencing on June 1, 2014. The 2018 Notes mature on December 1, 2018, and are redeemable at our option prior to maturity at prices specified in the Indenture. The Indenture contains negative covenants that restrict the ability of us and our restricted subsidiaries to engage in certain transactions, as described below, and also contains customary events of default.
	The Indenture contains certain covenants that restrict or limit our ability to, among other things,
	•	incur additional indebtedness or issue disqualified stock or preferred stock;
	•	pay dividends or make other distributions or repurchase or redeem our stock or subordinated indebtedness or make investments;
	•	prepay, redeem or repurchase certain debt;
	•	sell assets or issue capital stock of our restricted subsidiaries;
	•	incur liens;
	•	enter into agreements restricting our restricted subsidiaries’ ability to pay dividends, make loans to other U.S. Concrete entities or restrict the ability to provide liens;
	•	enter into transactions with affiliates;
	•	consolidate, merge or sell all or substantially all of our assets;
	•	engage in certain sale/leaseback transactions; and
	•	designate our subsidiaries as unrestricted subsidiaries.
	As defined in the Indenture, we are entitled to incur indebtedness if, on the date of such incurrence and given effect thereto on a proforma basis, the consolidated coverage ratio exceeds 2.0 to 1.0.
	Our obligations under the 2018 Notes are jointly and severally and fully and unconditionally guaranteed on a senior secured basis by each of our existing and future domestic subsidiaries that guarantee the indebtedness under the Revolving Facility. Each guarantee is subject to release in the following customary circumstances:
	•	a disposition of all or substantially all of the assets of the guarantor subsidiary, by way of merger, consolidation or otherwise; provided the proceeds of the disposition are applied in accordance with the Indenture;
	•	a disposition of the capital stock of the guarantor subsidiary to a third person, if the disposition complies with the Indenture and as a result the guarantor subsidiary ceases to be a restricted subsidiary;
	•	the designation by us of the guarantor subsidiary as an unrestricted subsidiary or the guarantor subsidiary otherwise ceases to be a restricted subsidiary, in each case in accordance with the Indenture; or
	•	legal or covenant defeasance of the 2018 Notes and discharge of our obligations under the Indenture.
	The 2018 Notes are issued by U.S. Concrete, Inc., the parent company, and are guaranteed on a full and unconditional basis by each of its indirect wholly owned subsidiaries. The guarantees are joint and several, and there are no non-guarantor subsidiaries. U.S. Concrete, Inc. does not have any independent assets or operations. There are no significant restrictions on the ability of the Company or any guarantor to obtain funds from its subsidiaries by dividend or loan.
	The 2018 Notes and the guarantees thereof rank equally in right of payment with all of our existing and future senior indebtedness. The 2018 Notes and the guarantees thereof are secured by first-priority liens on certain of the property and assets directly owned by us, including material owned real property, fixtures, intellectual property, capital stock of subsidiaries and certain equipment, subject to permitted liens and certain exceptions, and by a second-priority lien on the our assets securing the Revolving Facility on a first-priority basis, including inventory (including as-extracted collateral), accounts, certain specified mixer trucks, chattel paper, general intangibles (other than collateral securing the 2018 Notes on a first-priority basis), instruments, documents, cash, deposit accounts, securities accounts, commodities accounts, letter of credit rights and all supporting obligations and related books and records and all proceeds and products of the foregoing, subject to permitted liens and certain exceptions. The 2018 Notes and the guarantees thereof are effectively subordinated to all indebtedness and other obligations, including trade payables, of each of our future subsidiaries that are not guarantors.
	Senior Secured Credit Facility due 2018
	On August 31, 2012, we and certain of our subsidiaries entered into a Loan and Security Agreement (as subsequently amended, the "2012 Credit Agreement") with certain financial institutions named therein, as lenders, and Bank of America, N.A. as agent and sole lead arranger (the "Administrative Agent"), which provided for an $80.0 million asset-based revolving credit facility (the "Revolving Facility"). On March 28, 2013, we entered into a First Amendment to Loan and Security Agreement (the "Amendment") with certain financial institutions party thereto (the "Lenders") and the Administrative Agent, which amended the 2012 Credit Agreement. The Amendment, among other things, increased the Revolving Facility by $22.5 million from $80.0 million to $102.5 million. On October 29, 2013, we entered into a First Amended and Restated Loan and Security Agreement with the Lenders and the Administrative Agent, which amended and restated our 2012 Credit Agreement. The 2013 Loan Agreement, among other things, provided for an increase, upon the consummation of a refinancing of our 2013 Notes (a “Senior Notes Refinancing”), of the Revolving Facility from $102.5 million to $125.0 million and for an extension of the term of the agreement. The issuance of our 2018 Notes qualified as a Senior Notes Refinancing. As a result of the Senior Notes Refinancing, the expiration date of the 2013 Loan Agreement was extended to October 2, 2018. The Revolving Facility retains an uncommitted accordion feature that may allow for an increase in the total commitments under the facility to as much as $175.0 million. As of December 31, 2013 under the Revolving Facility, we had no outstanding borrowings and $11.3 million of undrawn standby letters of credit, and as of December 31, 2012, we had $13.3 million of outstanding borrowings and $12.2 million of undrawn standby letters of credit.
	Our actual maximum credit availability under the 2013 Loan Agreement varies from time to time and is determined by calculating the value of our eligible accounts receivable, inventory and vehicles, which serve as priority collateral on the facility, minus reserves imposed by the Lenders and other adjustments, all as specified in the 2013 Loan Agreement and discussed further below. Our availability under the Revolving Facility at December 31, 2013 increased to $88.3 million from $52.4 million at December 31, 2012. The 2013 Loan Agreement also contains a provision for discretionary over-advances and involuntary protective advances by Lenders of up to $12.5 million in excess of borrowing base levels. The 2013 Loan Agreement provides for swingline loans, up to a $10.0 million sublimit, and letters of credit, up to a $30.0 million sublimit.
	Advances under the Revolving Facility are in the form of either base rate loans or “LIBOR Loans” denominated in U.S. dollars. The interest rate for base rate loans denominated in U.S. dollars fluctuates and is equal to the greater of (a) Bank of America’s prime rate; (b) the Federal funds rate, plus 0.50%; or (c) the rate per annum for a 30 days interest period equal to the British Bankers Association LIBOR Rate, as published by Reuters at approximately 11:00 a.m. (London time) two business days prior (“LIBOR”), plus 1.0%; in each case plus the Applicable Margin, as defined in the 2013 Loan Agreement. The interest rate for LIBOR Loans denominated in U.S. dollars is equal to the rate per annum for the applicable interest period equal to LIBOR, plus the Applicable Margin, as defined in the 2013 Loan Agreement. Issued and outstanding letters of credit are subject to a fee equal to the Applicable Margin, as defined in the 2013 Loan Agreement, a fronting fee equal to 0.125% per annum on the stated amount of such letter of credit, and customary charges associated with the issuance and administration of letters of credit. Among other fees, we pay a commitment fee of either 0.25% or 0.375% per annum (due monthly) on the aggregate unused revolving commitments under the Revolving Facility. The fee we pay is determined by whether the amount of the unused line is above or below 50% of the Aggregate Revolver Commitments, as defined in the 2013 Loan Agreement. The Applicable Margin ranges from 0.25% to 0.75% for base rate loans and from 1.5% to 2.0% for LIBOR Loans, and is determined based on Average Availability for the most recent fiscal quarter, as defined in the 2013 Loan Agreement.
	Up to $30.0 million of the Revolving Facility is available for the issuance of letters of credit, and any such issuance of letters of credit will reduce the amount available for loans under the Revolving Facility. Advances under the Revolving Facility are limited by a borrowing base which is equal to the lesser of the Revolving Facility minus the LC Reserve, the Senior Notes Availability Reserve, and the Tax Reserve, all as defined in the 2013 Loan Agreement, or the sum of (a) 90% of the face amount of eligible accounts receivable (reduced to 85% under certain circumstances), plus (b) the lesser of (i) 55% of the value of eligible inventory or (ii) 85% of the product of (x) the net orderly liquidation value of inventory divided by the value of the inventory and (y) multiplied by the value of eligible inventory, and (c) the lesser of (i) $30.0 million (which may increase up to $40.0 million on the occasion of a Revolver Commitments Increase Event, as defined in the 2013 Loan Agreement), or (ii) the sum of (A) 85% of the net orderly liquidation value (as determined by the most recent appraisal) of eligible trucks plus (B) 80% of the cost of newly acquired eligible trucks since the date of the latest appraisal of eligible trucks minus (C) 85% of the net orderly liquidation value of eligible trucks that have been sold since the latest appraisal date and 85% of the depreciation amount applicable to eligible trucks since the date of the latest appraisal of eligible trucks, minus (D) such reserves as the Administrative Agent may establish from time to time in its permitted discretion. The Administrative Agent may, in its permitted discretion, reduce the advance rates set forth above, adjust reserves or reduce one or more of the other elements used in computing the borrowing base.
	The 2013 Loan Agreement contains usual and customary negative covenants for transactions of this type, including, but not limited to, restrictions on our ability to consolidate or merge; substantially change the nature of our business; sell, lease or otherwise transfer any of our assets; create or incur indebtedness; create liens; pay dividends; and make investments or acquisitions. The negative covenants are subject to certain exceptions as specified in the 2013 Loan Agreement. The 2013 Loan Agreement also requires that we, upon the occurrence of certain events, maintain a fixed charge coverage ratio of at least 1.0 to 1.0 for each period of twelve calendar months, as determined in accordance with the 2013 Loan Agreement. For the trailing twelve month period ended December 31, 2013, our fixed charge coverage ratio was 2.77 to 1.0. As of December 31, 2013, we were in compliance with all covenants under the 2013 Loan Agreement.
	The 2013 Loan Agreement also includes customary events of default, including, among other things, payment default, covenant default, breach of representation or warranty, bankruptcy, cross-default, material ERISA events, change of control, material money judgments and failure to maintain subsidiary guarantees.
	The 2013 Loan Agreement is secured by a first-priority lien on certain assets of the Company and our guarantors, including inventory (including as extracted collateral), accounts, certain specified mixer trucks, general intangibles (other than collateral securing the 2018 Notes on a first-priority basis, as described above), instruments, documents, chattel paper, cash, deposit accounts, securities accounts, commodities accounts, letter of credit rights and all supporting obligations and related books and records and all proceeds and products of the foregoing, subject to permitted liens and certain exceptions.  The 2013 Loan Agreement is also secured by a second-priority lien on the collateral securing the 2018 Notes as defined below on a first-priority basis (see “Senior Secured Notes due 2018” above).
	Senior Secured Notes due 2015
	On March 22, 2013, we completed our offer to exchange (the “Exchange Offer”) up to $69.3 million aggregate principal amount of newly issued 2013 Notes for all $55.0 million aggregate principal amount of our Convertible Notes. At the time of settlement, we issued $61.1 million aggregate principal amount of 2013 Notes in exchange for $48.5 million of Convertible Notes, plus approximately $0.3 million in cash for accrued and unpaid interest on the Convertible Notes exchanged in the Exchange Offer. After giving effect to the exchange, $6.5 million aggregate principal amount of Convertible Notes remained outstanding as of March 22, 2013 (see additional information under "Convertible Notes due 2015" below).
	In November 2013, we used a portion of the proceeds from our 2018 Notes offering to redeem all $61.1 million of our outstanding 2013 Notes. See Note 10 for additional information regarding the extinguishment of this debt.
	Convertible Secured Notes due 2015
	On August 31, 2010, we issued $55.0 million aggregate principal amount of Convertible Notes. The Convertible Notes are governed by an indenture, dated as of August 31, 2010 (the "2010 Indenture"). Under the terms of the 2010 Indenture, the Convertible Notes bore interest at a rate of 9.5% per annum and will mature on August 31, 2015. Interest payments were payable quarterly in cash in arrears. Additionally, we recorded a discount of approximately $13.6 million related to an embedded derivative that was bifurcated and separately valued (see Note 11). This discount was being accreted over the term of the Convertible Notes and included in interest expense prior to the Conversion Event, as described below. As of December 31, 2013 and 2012, the unamortized balance of the discount was zero and $8.9 million, respectively.
	Immediately prior to the consummation of the Exchange Offer, we entered into a Second Supplemental Indenture, dated as of March 22, 2013 (the “Supplemental Indenture”). The Supplemental Indenture amended the 2010 Indenture to eliminate the following: substantially all of the restrictive covenants contained in the 2010 Indenture, including the requirement to meet a consolidated secured debt ratio test and the limitations on additional indebtedness; the provisions regarding purchase at the option of the holder upon a fundamental change in control; and certain events of default. The Supplemental Indenture also provided for a release of all of the liens on the collateral securing the Convertible Notes and securing the related guarantees under the 2010 Indenture. After giving effect to the exchange, $6.5 million aggregate principal amount of Convertible Notes remained outstanding as of March 22, 2013.
	In accordance with the terms of the 2010 Indenture, as amended, if the closing price of our common stock exceeded 150% of the Conversion Price (defined in the 2010 Indenture as $1,000 divided by the Conversion Rate) then in effect for at least 20 trading days during any consecutive 30-days trading period (the "Conversion Event"), we could provide, at our option, a written notice (the "Conversion Event Notice"), of the occurrence of the Conversion Event to each holder of Convertible Notes.  Except as set forth in an Election Notice (as defined in the 2010 Indenture), the right to convert Convertible Notes with respect to the occurrence of the Conversion Event terminated on the date that was 46-days following the date of the Conversion Event Notice (the "Conversion Termination Date"), such that the holder had a 45-days period in which to convert its Convertible Notes. Any Convertible Notes not otherwise converted prior to the Conversion Termination Date or specified for conversion in an Election Notice could be redeemed, in whole or in part, at our election at any time prior to maturity at par plus accrued and unpaid interest thereon to the Conversion Termination Date.
	On June 17, 2013, the common stock price hurdle necessary to constitute a Conversion Event was met. As such, we provided a Conversion Event Notice to the remaining holders of Convertible Notes on June 18, 2013. Holders had until the close of business on August 2, 2013, the Conversion Termination Date, to tender their Convertible Notes for shares of common stock. Prior to August 3, 2013, holders tendered $6.4 million of Convertible Notes and were issued 0.6 million shares of our common stock. As of August 3, 2013, the remaining Convertible Notes no longer include a conversion feature and ceased to accrue interest. After giving effect to the tendered Convertible Notes, $0.1 million aggregate principal amount of Convertible Notes remained outstanding as of December 31, 2013.
	For the years ended December 31, 2013 and 2012, we recorded to our consolidated statements of operations, interest expense related to the coupon rate and amortization of the discount on our Convertible Notes of $2.1 million and $7.5 million, respectively. The weighted average interest rate for the Convertible Notes was zero and 17.38% as of December 31, 2013 and 2012, respectively.
	Capital Leases and Other Financing
	On July 23, 2013, we entered into a master leasing agreement with Capital One Equipment Finance Corporation ("Capital One") to provide up to $5.0 million in total lease commitments for mixer trucks. As of December 31, 2013, we have utilized all $5.0 million of lease commitments at fixed annual interest rates ranging from 4.31% to 4.54%. Payments are due monthly for a term of five years. The lease terms include a one dollar buyout option at the end of the lease term. Accordingly, this financing has been classified as a capital lease.
	On December 19, 2013, we entered into a master leasing agreement with GE Corporate Financial Services, Inc. ("GE Capital") to provide up to $5.0 million in total lease commitments for mixer trucks. As of December 31, 2013, we have utilized $0.8 million of lease commitments with a fixed interest rate of 4.80% per annum, payable monthly for a term of five years. The lease terms include a one dollar buyout option at the end of the lease term. Accordingly, this financing has been classified as a capital lease.
	The current portion of capital leases included in current maturities of long term debt is $1.1 million as of December 31, 2013.
Between July 26, 2013 and December 31, 2013, we signed four promissory notes with Daimler Truck Financial ("Daimler") for the purchase of mixer trucks in the aggregate amount of $6.2 million with annual interest rates ranging from 3.02% to 3.23%. The Daimler promissory notes are payable monthly for a term of five years.
The weighted average interest rate of our capital leases and other financing was 3.83% as of December 31, 2013 and was 4.22% at December 31, 2012.

	EXTINGUISHMENT OF DEBT
	As described in Note 9 above, concurrent with issuing the 2018 Notes in November 2013, we redeemed our $61.1 million of outstanding 2013 Notes issued in connection with the Exchange Offer. As such, during the fourth quarter of 2013, we wrote-off $1.6 million of previously deferred financing costs associated with 2013 Notes and recorded the charge as loss on extinguishment of debt on the accompanying consolidated statements of operations.
	In conjunction with the Conversion Event, described in Note 9 above, holders of our Convertible Notes tendered $6.4 million of Convertible Notes in exchange for 0.6 million shares of our common stock. As a result of the Conversion Event, during the third quarter of 2013, we wrote-off $0.3 million of previously deferred financing costs, $3.7 million of derivative liabilities, and $0.8 million of unamortized discount. We recorded a loss on extinguishment of debt of $1.7 million, which is included on the accompanying consolidated statements of operations.
	In March 2013, in connection with the Exchange Offer, described in Note 9 above, we exchanged $48.5 million of Convertible Notes for $61.1 million of 2013 Notes.  As a result of the Exchange Offer, during the first quarter of 2013, we wrote-off $2.4 million of previously deferred financing costs, $26.6 million in derivative liabilities, and $7.3 million of unamortized discount. We recorded a gain on extinguishment of debt associated with this transaction of $4.3 million on the accompanying consolidated statements of operations.
	In August 2012, concurrent with entering into the 2012 Credit Agreement, we terminated our Senior Secured Credit Facility due 2014 (the "2010 Agreement"). As such, during the third quarter of 2012, we wrote-off $2.6 million of previously deferred financing costs associated with the terminated 2010 Credit Agreement and recorded the charge as loss on extinguishment of debt on the accompanying consolidated statements of operations.
	In connection with the 2018 Notes, the 2012 Credit Agreement and the 2013 Loan Agreement we have incurred $8.5 million of deferred financing costs. Deferred financing costs are classified as Other Assets on the accompanying consolidated balance sheet. These deferred financing costs are being amortized over the terms of the related agreements using the straight line method, which approximated the effective interest method.

	We are exposed to certain risks relating to our ongoing business operations.  However, derivative instruments are not used to hedge these risks.  We are required to account for derivative instruments as a result of the issuance of the Warrants and Convertible Notes on August 31, 2010. None of our derivative contracts manage business risk or are executed for speculative purposes. Our Convertible Notes embedded derivative was written-off as of the Conversion Termination Date as discussed in Notes 9 and 10 above, as the remaining note holders no longer have conversion rights.

	OTHER LONG-TERM OBLIGATIONS AND DEFERRED CREDITS
	Other long-term obligations and deferred credits are comprised primarily of the Bode Earn-out that we entered into with the former equity owners of the Bode Companies, as part of the acquisition of the Bode Companies during the fourth quarter of 2012. In accordance with the agreement, we are obligated to make certain annual payments to the former owners of the Bode Companies upon the achievement of certain pre-defined incremental sales volume milestones. The Bode Earn-out was valued based on the net present value of the expected future payments, using a contractual discount rate of 7.0% and is capped at a net present value of $7.0 million. A long-term obligation of $4.8 million and $7.0 million is classified as a long-term liability on our consolidated balance sheets at December 31, 2013 and 2012, respectively, and reflects the portion we expect to pay beyond one year of the balance sheet date and within the six-year term of the agreement. The discount on the Bode Earn-out is being accreted to interest expense over the period during which payments are expected to be made. Our first payment is due in January 2014. We expect our obligation to cease during 2017.
	The remaining other long-term obligations and deferred credits balances consists primarily of the long-term portion of our income tax liability (see Note 17).

Fair Value Disclosures [Abstract]	'
FAIR VALUE DISCLOSURES	'
	FAIR VALUE DISCLOSURES
	Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Accounting guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of us. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability. The guidance establishes three levels of inputs that may be used to measure fair value:
	Level 1—Quoted prices in active markets for identical assets or liabilities.
	Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the  full term of the assets or liabilities.
	Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurements. We review the fair value hierarchy classification on a quarterly basis. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy.
	The following table presents our fair value hierarchy for liabilities measured at fair value on a recurring basis as of December 31, 2013 and 2012 (in thousands):
			As of December 31, 2013
			Total		Level 1			Level 2		Level 3

	-1	Represents the Warrants (as defined herein, see Note 15).
	-2	Represented the compound embedded derivative included in our Convertible Notes (see Note 11). The compound embedded derivative included the value associated with the noteholders’ conversion option, as well as certain rights to receive “make-whole” amounts. The “make-whole” provision(s) provided that, upon certain contingent events, if conversion was elected on the Convertible Notes, we may have been obligated to pay such holder an amount in cash, or shares of common stock to compensate noteholders who had converted early as a result of these contingent events, interest and time value of the conversion option foregone via the conversion.
	-3	Represents the fair value of the Bode Earn-out (see Note 2). The fair value was determined based on expected payouts that will be due to the former owners based on the achievement of certain incremental sales volume milestones, using a contractual discount rate of 7.0%. These payments are capped at a fair value of $7.0 million.
	The Convertible Notes embedded derivative liability was valued using a lattice model for instruments with the option to convert into common equity. Following the Conversion Termination Date in August 2013, the remaining Convertible Notes are no longer convertible into shares of our common stock and, as a result, the Convertible Notes no longer include an embedded derivative. The liability for the Warrants was valued utilizing a Black-Scholes-Merton model. Inputs into the model were based upon observable market data where possible.  Where observable market data did not exist, the Company modeled inputs based upon similar observable inputs. The key inputs in determining fair value of our derivative liabilities include our stock price, stock price volatility, risk free interest rates and interest rates for conventional debt of similarly situated companies.
	A reconciliation of the changes in Level 3 fair value measurements is as follows for December 31, 2013 and 2012 (in thousands):
			Warrants		Convertible Notes Embedded			Bode Earn-out

	-2	Represents the pro rata portion of derivative liability associated with tendered Convertible Notes measured at the date of tender or remaining at the Conversion Termination Date, which is included in additional paid-in capital on the accompanying consolidated balance sheet for the year ended December 31, 2013.
	Our other financial instruments consist of cash and cash equivalents, trade receivables, trade payables and long-term debt.  We consider the carrying values of cash and cash equivalents, trade receivables and trade payables to be representative of their respective fair values because of their short-term maturities or expected settlement dates.  The carrying value of outstanding amounts under our 2013 Loan Agreement approximates fair value due to the floating interest rate. The fair value of the 2018 Notes, estimated based on broker/deal quoted market prices, was $204.5 million as of December 31, 2013. The fair value of our Convertible Notes was approximately $0.1 million and included no embedded derivative at December 31, 2013, and was $68.8 million, including $17.2 million related to the embedded derivative at December 31, 2012.

WARRANTS	'
	WARRANTS
	On August 31, 2010 (the "Effective Date"), we issued warrants to acquire common stock in two tranches: Class A Warrants to purchase an aggregate of approximately 1.5 million shares of common stock, and Class B Warrants to purchase an aggregate of approximately 1.5 million shares of common stock (collectively, the "Warrants").  The Warrants were issued to holders of our predecessor common stock pro rata based on a holder’s stock ownership as of the Effective Date. The Warrants have been included in derivative liabilities on the consolidated balance sheets in accordance with the authoritative accounting guidance (see Note 11).
	In connection with the issuance of the Class A Warrants, we entered into a Class A Warrant Agreement with American Stock Transfer & Trust Company, LLC, as warrant agent ("AST").  Subject to the terms of the Class A Warrant Agreement, holders of Class A Warrants are entitled to purchase shares of common stock at an exercise price of $22.69 per share.  In connection with the issuance of the Class B Warrants, the Company entered into a Class B Warrant Agreement (collectively with the Class A Warrant Agreement, the "Warrant Agreements") with AST.  Subject to the terms of the Class B Warrant Agreement, holders of Class B Warrants are entitled to purchase shares of common stock at an exercise price of $26.68 per share.  Subject to the terms of the Warrant Agreements, both classes of Warrants have a seven−year term and will expire on the seventh anniversary of the Effective Date.  The Warrants may be exercised for cash or on a net issuance basis.
	If, at any time before the expiration date of the Warrants, we pay or declare a dividend or make a distribution on the common stock payable in shares of our capital stock, or make subdivisions or combinations of our outstanding shares of common stock into a greater or lesser number of shares or issue any shares of our capital stock by reclassification of common stock, then the exercise price and number of shares issuable upon exercise of the Warrants will be adjusted so that the holders of the Warrants will be entitled to receive the aggregate number and kind of shares that they would have received as a result of the event if their Warrants had been exercised immediately before the event.  In addition, if we distribute to holders of the common stock an Extraordinary Distribution (defined in each Warrant Agreement to include assets, securities or warrants to purchase securities), then the exercise price of the Warrants will be decreased by the amount of cash and/or the fair market value of any securities or assets paid or distributed on each share of common stock; however, no adjustment to the exercise price will be made if, at the time of an Extraordinary Distribution, we make the same distribution to holders of Warrants as we make to holders of common stock pro rata based on the number of shares of common stock for which the Warrants are exercisable.
	In the event of a Fundamental Change (defined in each Warrant Agreement to include transactions such as mergers, consolidations, sales of assets, tender offers, exchange offers, reorganizations, reclassifications, compulsory share exchanges or liquidations in which all or substantially all of the outstanding common stock is converted into or exchanged for stock, other securities, cash or assets), if the consideration paid consists 90% or more of publicly traded securities, each holder of a Warrant will have the right upon any subsequent exercise to receive the kind and amount of stock, other securities, cash and assets that such holder would have received if the Warrant had been exercised immediately prior to such Fundamental Change.  If a Fundamental Change occurs (other than a Fundamental Change in which the consideration paid consists at least 90% of publicly traded securities), then each holder of a Warrant will be entitled to receive an amount equal to the Fair Market Value (as defined in each of the Warrant Agreements) of their Warrant on the date the Fundamental Change is consummated.
	No adjustment in the exercise price of Warrants shall be required unless such adjustment would require an increase or decrease of at least $0.05 in the exercise price; provided that any adjustments that are not required to be made shall be carried forward and taken into account in any subsequent adjustment.

	CORPORATE HEADQUARTERS RELOCATION AND LEASE EXIT COSTS
	During the first quarter of 2012, we made the decision to relocate our corporate headquarters from Houston, Texas to Euless, Texas. The move was completed in July 2012. As a result of this decision, we have paid severance costs to employees that did not relocate with the Company as well as other employee-related and general moving costs. For the years ended December 31, 2013 and 2012, we recorded approximately $0.7 million and $2.2 million, respectively, for these severance, other employee-related, and moving costs. These costs are included in selling, general, and administrative ("SG&A") expenses on the consolidated statements of operations.
	In connection with the relocation, we ceased use of our leased corporate office space in Houston effective July 21, 2012. As a result, during the third quarter of 2012, we recorded a $0.4 million non-cash charge to SG&A expenses for the net present value of the difference between the remaining lease payments and the market value we believe we could obtain for a sublease of the space over the remainder of the term. We continued to incur rent expense for the remainder of the lease term, which we included in SG&A expenses; and the expense was being reduced by the amortization of the cease-use obligation over the remaining lease term. The associated nominal accretion expense was included as a charge to SG&A expenses over the remaining lease term. During the third quarter of 2013, we signed an agreement with the landlord to terminate the lease for a payment of $0.2 million. Prior to the lease termination, we did not sublease the space and recorded no rental income. We recorded credits of approximately $0.1 million in amortization of the cease-use obligation for each of the years ended December 31, 2013 and 2012.

	Long-term deferred tax liability, net	5,040			3,287
	Net deferred tax liability	$	4,332		$	452
	In accordance with U.S. GAAP, the recognized value of deferred tax assets must be reduced to the amount that is more likely than not to be realized in future periods.  The ultimate realization of the benefit of deferred tax assets from deductible temporary differences or tax carryovers depends on the generation of sufficient taxable income during the periods in which those temporary differences become deductible.  We considered the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment.  Based on these considerations, we relied upon the reversal of certain deferred tax liabilities to realize a portion of our deferred tax assets and established valuation allowances as of December 31, 2013 and 2012 in the amount of $44.4 million and $44.9 million, respectively, for other deferred tax assets because of uncertainty regarding their ultimate realization.  Our total net deferred tax liability as of December 31, 2013 and 2012 was $4.3 million and $0.5 million, respectively.
	We reorganized pursuant to Chapter 11 of the bankruptcy code under the terms of our plan of reorganization (the "Plan"), with an effective date of August 31, 2010.  Under our Plan, our previously outstanding 8.375% Senior Subordinated Notes due 2014 were cancelled, giving rise to cancellation of indebtedness income, or CODI.  The Internal Revenue Code ("IRC"), provides that CODI arising under a plan of bankruptcy reorganization is excludable from taxable income, but the debtor must reduce certain of its tax attributes by the amount of CODI realized under the Plan.  Based on the estimate of CODI and required tax attribute reduction, the effects of the Plan did not cause a significant change in our recorded net deferred tax liability.  Our required reduction in tax attributes, or deferred tax assets, was accompanied by a corresponding release of valuation allowance that was reducing the carrying value of such tax attributes.
	We underwent a change in ownership for purposes of Section 382 of the IRC as a result of our Plan and emergence from Chapter 11 on August 31, 2010.  As a result, the amount of our pre-change net operating losses, or NOL's, and other tax attributes that are available to offset future taxable income are subject to an annual limitation.  The annual limitation is based on the value of the corporation as of the effective date of the Plan. As of December 31, 2013, approximately $25.8 million of our $56.0 million federal NOL’s are subject to annual Section 382 limitations. The ownership change and the resulting annual limitation on use of NOL's are not expected to result in the expiration of our NOL carryforwards if we are able to generate sufficient future taxable income within the carryforward periods.  However, the limitation on the amount of NOL available to offset taxable income in a specific year may result in the payment of income taxes before all NOL's have been utilized.  Additionally, a subsequent ownership change may result in further limitation on the ability to utilize existing NOL's and other tax attributes.
	As of December 31, 2013, we had deferred tax assets related to federal and state NOL and tax credit carryforwards of $26.6 million.  As a result of certain realization requirements of ASC Topic 718, Compensation - Stock Compensation, these deferred tax assets do not include $3.0 million that arose directly from tax deductions related to equity compensation in excess of compensation recognized for financial reporting. We have federal NOL's of approximately $56.0 million, including $8.7 million related to the excluded deferred tax assets related to equity compensation, that are available to offset federal taxable income and will expire in the years 2028 through 2032, if not fully utilized.
	At December 31, 2013, we had unrecognized tax benefits of $3.5 million of which $1.5 million, if recognized, would impact the effective tax rate. It is likely a reduction of unrecognized tax benefits will occur within the next 12 months of $0.1 million. The unrecognized tax benefits are included as a component of other long-term obligations. During the years ended December 31, 2013 and December 31, 2012, we recorded interest and penalties related to unrecognized tax benefits of $0.1 million and ($0.1) million, respectively.  Total accrued penalties and interest at December 31, 2013 and 2012 was approximately $0.3 million and $0.2 million, respectively.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):
	Balance as of January 1, 2012	$	6,556
	Additions for tax positions related to 2012	145
	Additions for tax positions related to prior years	508
Reductions due to lapse of statute of limitations	(611		)

Additions for tax positions related to prior years	393
Reductions due to lapse of statute of limitations	(3,813		)
Balance as of December 31, 2013	$	3,489
We recognize interest and penalties related to uncertain tax positions in income tax expense.
We conduct business domestically and, as a result, U.S. Concrete, Inc. or one or more of our subsidiaries file income tax returns in the U.S. federal jurisdiction and various state and local jurisdictions. In the normal course of business, we are subject to examination in the U.S. federal jurisdiction, and generally in state jurisdictions. With few exceptions, we are no longer subject to U.S. federal, state and local tax examinations for years before 2010.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]	'
STOCK-BASED COMPENSATION	'
	STOCK-BASED COMPENSATION
	Management Equity Incentive Plan
	We adopted a management equity incentive plan (the "2010 Plan") on the Effective Date, under which 9.5% of the equity of the Company, on a fully-diluted basis, was reserved for issuance as equity-based awards to management and employees, and 0.5% of such equity, on a fully-diluted basis, was reserved for issuance to directors of the Company. On January 23, 2013, we adopted a long term incentive plan (the "2013 Plan"), under which approximately 0.5 million shares of common stock are reserved for grant as equity-based awards to management, employees, and directors of the Company. The 2013 Plan was approved by stockholders at our annual meeting in May 2013. The 2013 Plan enables us to grant stock options, stock appreciation rights, stock awards, cash awards and performance awards.
	We reserved 2.7 million shares of common stock for use in connection with the 2010 Plan and the 2013 Plan, and as of December 31, 2013, there were 1.1 million shares remaining for future issuance under the 2013 Plan.  Following the adoption of the 2013 Plan, we no longer grant awards under the 2010 Plan.
	In accordance with the terms of the 2010 Plan, by no later than the fifth anniversary of the Effective Date, all shares of common stock reserved for issuance under the 2010 Plan are required to be subject to an outstanding award or to have been delivered pursuant to the settlement of an award.  Within thirty days following the Effective Date, thirty-five percent of the shares of common stock available for delivery pursuant to awards were required to be allocated to employee awards.  No more than five percent of the shares of common stock available for delivery pursuant to awards were to be allocated to director awards.  Each participant who received an award in the form of restricted stock units from the 2010 Plan also concurrently received an award for an equal amount of incentive restricted stock units (which represent the right to receive 0.35020 of a share of common stock upon satisfaction of certain criteria).
	Stock-Based Compensation
	Under authoritative accounting guidance, share-based compensation cost is measured at the grant date based on the calculated fair value of the award. The expense is recognized over the employee’s requisite service period, generally the vesting period of the award or for performance based awards, over the derived service period.  We have elected to use the long-form method of determining our pool of windfall tax benefits as prescribed under authoritative accounting guidance.
	For the years ended December 31, 2013 and December 31, 2012, we recognized stock-based compensation expense related to restricted stock, restricted stock units and stock options of $5.4 million and $2.5 million, respectively. Stock-based compensation expense is reflected in SG&A expenses in our consolidated statements of operations.
	As of December 31, 2013 and 2012, there was approximately $3.1 million and $3.5 million, respectively, of unrecognized compensation cost related to restricted stock units, restricted stock awards and stock options. As of December 31, 2013, we expect to recognize the related compensation cost over a weighted average period of approximately 0.9 years.
	Restricted Stock Units
	Since August 31, 2010, we have issued restricted stock units under the 2010 and 2013 Plans that generally vest over a one to three year period on a quarterly basis.  The restricted stock units are subject to restrictions on transfer and certain conditions to vesting.  During the restriction period, the holders of restricted stock units are not entitled to vote and receive dividends on those restricted units as the restricted stock units do not represent outstanding shares of our common stock.
	Restricted stock unit activity for the years ending December 31, 2013 and December 31, 2012 was as follows (shares in thousands):
		For the years ended December 31,
		2013						2012
		Number		Weighted-				Number			Weighted-
		of		Average				of			Average
		Units		Grant Date				Units			Grant Date
				Fair Value							Fair Value

	Vested	(108	)	13.2				(117	)		7.78
	Forfeited	(1	)	8				(21	)		7.99
	Unvested restricted stock units outstanding at end of period	29		$	19.78			37			$	8.09
	Under the terms of the 2010 Plan, for every restricted stock unit that was granted, there was an equivalent number of incentive restricted stock units, or IRSU's, issued. These IRSU's represented the right to receive 0.35020 of a share of common stock upon satisfaction of certain criteria. The fair value of our restricted stock units was determined based upon the stock price of our common stock on the date of grant. Compensation expense associated with awards of restricted stock units was $2.7 million and $0.7 million for the years ended December 31, 2013 and December 31, 2012, respectively. Compensation costs for 2013 associated with our restricted stock units included $1.2 million of expense for achievement of the performance goal associated with the related IRSU's. The performance goal associated with delivery of a Conversion Event Notice was met on June 18, 2013, which triggered the conversion of certain previously vested IRSU's, resulting in the issuance of approximately 69,000 shares of our common stock and recognition of $1.2 million of compensation expense. Prior to the second quarter of 2013, no compensation expense had been recognized for these grants, as achievement of the performance goal was not considered probable. The weighted average remaining contractual term for the restricted stock units was 0.49 years at December 31, 2013.
	Restricted Stock Awards
	We have issued restricted stock awards under the 2010 and 2013 Plans. The restricted stock awards are subject to restrictions on transfer and certain conditions to vesting.  The restricted stock awards issued to date consist of a 60% time-vested component and a 40% stock performance hurdle component. The time-vested component vests over a three or four year period. The stock performance hurdle component triggers vesting upon our stock price reaching certain thresholds. During the restriction period, the holders of restricted stock are entitled to vote and receive dividends, thus these awards are included in our outstanding shares of common stock.
	Restricted stock award activity for the year ended December 31, 2013 and December 31, 2012 was as follows (shares in thousands):
		For the years ended December 31,
		2013						2012
		Number		Weighted-				Number			Weighted-
		of		Average				of			Average
		Shares		Grant Date				Shares			Grant Date
				Fair Value							Fair Value
	Unvested restricted stock awards outstanding at beginning of period	1,070		$	4.18			750			$	4.74
	Granted	214		11.55				492			3.51
	Vested	(748	)	4				(112	)		6
	Forfeited	(49	)	7.28				(60	)		3.4
	Unvested restricted stock awards outstanding at end of period	487		$	7.4			1,070			$	4.18
	The fair value of restricted stock awards subject only to time-vesting restrictions was determined based upon the stock price of our common stock on the date of grant. The fair value of restricted stock subject to our common stock reaching certain price thresholds was determined utilizing a Monte Carlo financial valuation model which is appropriate for path-dependent options. Compensation expense determined utilizing the Monte Carlo simulation is recognized regardless of whether the common stock reaches the defined thresholds. During 2012, we modified the terms of one of our restricted stock awards issued during 2011, resulting in a change in the stock performance hurdle and the valuation of the related shares. The incremental compensation expense associated with the modification of these 0.2 million of restricted stock awards was negligible for 2012. Compensation expense associated with restricted stock awards under our incentive compensation plan was $2.7 million and $1.8 million for the years ended December 31, 2013 and December 31, 2012, respectively.
	Stock Options
	Proceeds from the exercise of stock options are credited to common stock at par value, and the excess is credited to additional paid-in capital. We estimated the fair value of each of our stock option awards on the date of grant using a Black-Scholes option pricing model.  We determined the expected volatility using the historical and implied volatilities of a peer group of companies given the limited trading history of our successor common stock.  For each option awarded, the risk-free interest rate was based on the U.S. Treasury yield in effect at the time of grant for periods corresponding with the expected life of the option.  The expected life of an option represents the weighted average period of time that an option grant is expected to be outstanding, giving consideration to its vesting schedule and historical exercise patterns. We granted approximately 245,000 stock options during the fourth quarter of 2010.
	There were no stock option grants in 2013 or 2012, and stock option grants in 2011 were not material. Compensation expense related to stock options was less than $0.1 million during each of the years ended December 31, 2013 and December 31, 2012.  Stock option activity for the years ended December 31, 2013 and December 31, 2012 is as follows (shares in thousands):

Segment Reporting [Abstract]	'
BUSINESS SEGMENTS	'
	BUSINESS SEGMENTS
	Our two reportable segments consist of ready-mixed concrete and aggregate products, as described below.
	Our ready-mixed concrete segment produces and sells ready-mixed concrete. This segment serves the following principal markets: north and west Texas, California, New Jersey, New York, Washington, D.C. and Oklahoma. Our aggregate products segment includes crushed stone, sand and gravel products and serves the north and west Texas, New Jersey, and New York markets in which our ready-mixed concrete segment operates. Other products not associated with a reportable segment include our building materials stores, hauling operations, lime slurry, Aridus® rapid-drying concrete technology, brokered product sales, a recycled aggregates operation, and one remaining precast concrete plant in Pennsylvania.
	Our customers are generally involved in the construction industry, which is a cyclical business and is subject to general and more localized economic conditions.  In addition, our business is impacted by seasonal variations in weather conditions, which vary by regional market.  Accordingly, demand for our products and services during the winter months are typically lower than in other months of the year because of inclement weather.  Also, sustained periods of inclement weather and other adverse weather conditions could cause the delay of construction projects during other times of the year.
	Our chief operating decision maker evaluates segment performance and allocates resources based on Adjusted EBITDA. We define Adjusted EBITDA as net income (loss) from continuing operations excluding interest, income taxes, depreciation, depletion and amortization, derivative gain (loss), and gain or loss on extinguishment of debt. Additionally, we adjust Adjusted EBITDA for items similar to certain of those used in calculating the Company’s compliance with debt covenants. The additional items that are adjusted to determine our Adjusted EBITDA are:
	•	non-cash stock compensation expense;
	•	corporate officer severance expense; and
	•	expenses associated with the relocation of our corporate headquarters.
	We consider Adjusted EBITDA to be an indicator of the operational strength and performance of our business. We have included Adjusted EBITDA because it is a key financial measure used by our management to (i) internally measure our operating performance and (ii) assess our ability to service our debt, incur additional debt and meet our capital expenditure requirements.
	Adjusted EBITDA should not be construed as an alternative to, or a better indicator of, net income or loss, is not based on U.S. GAAP, and is not necessarily a measure of our cash flows or ability to fund our cash needs. Our measurements of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies.
	We account for inter-segment sales at market prices. Corporate includes executive, administrative, financial, legal, human resources, business development and risk management activities which are not allocated to reportable segments and are excluded from segment Adjusted EBITDA. Eliminations include transactions to account for intercompany activity. Certain prior year amounts have been recast to conform to the current year presentation.

	RISK CONCENTRATION
	We grant credit, generally without collateral, to our customers, which include general contractors, municipalities and commercial companies located primarily in Texas, California, New Jersey, New York, Pennsylvania, Washington D.C., and Oklahoma. Consequently, we are subject to potential credit risk related to changes in business and economic factors in those states.  We generally have lien rights in the work we perform, and concentrations of credit risk are limited because of the diversity of our customer base. Further, our management believes that our contract acceptance, billing and collection policies are adequate to limit potential credit risk.
	Several of our subsidiaries are parties to various collective bargaining agreements with labor unions having multi-year terms.  As of December 31, 2013, approximately 575 of our employees, or 32.2% of our workforce, were represented by labor unions having collective bargaining agreements with us. Generally, these agreements have multi-year terms and expire on a staggered basis between 2014 and 2018. As of December 31, 2013, approximately 84 of our employees, or 4.6% of our workforce, were represented by agreements that expire within one year.

	COMMITMENTS AND CONTINGENCIES
	Legal Proceedings
	From time to time, and currently, we are subject to various claims and litigation brought by employees, customers and other third parties for, among other matters, personal injuries, property damages, product defects and delay damages that have, or allegedly have, resulted from the conduct of our operations.  As a result of these types of claims and litigation, we must periodically evaluate the probability of damages being assessed against us and the range of possible outcomes.  In each reporting period, if we determine that the likelihood of damages being assessed against us is probable, and, if we believe we can estimate a range of possible outcomes, then we will record a liability. The amount of the liability will be based upon a specific estimate, if we believe a specific estimate to be likely, or it will reflect the low end of our range. Currently, there are no material legal proceedings pending against us.
	In the future, we may receive funding deficiency demands related to multi-employer pension plans to which we contribute.  We are unable to estimate the amount of any potential future funding deficiency demands because the actions of each of the other contributing employers in the plans has an effect on each of the other contributing employers, and the development of a rehabilitation plan by the trustees and subsequent submittal to and approval by the Internal Revenue Service is not predictable. Further, the allocation of fund assets and return assumptions by trustees are variable, as are actual investment returns relative to the plan assumptions.
	As of March 6, 2014, there are no material product defect claims pending against us.  Accordingly, our existing accruals for claims against us do not reflect any material amounts relating to product defect claims.  While our management is not aware of any facts that would reasonably be expected to lead to material product defect claims against us that would have a material adverse effect on our business, financial condition or results of operations, it is possible that claims could be asserted against us in the future.  We do not maintain insurance that would cover all damages resulting from product defect claims.  In particular, we generally do not maintain insurance coverage for the cost of removing and rebuilding structures, or so-called “rip and tear” coverage.  In addition, our indemnification arrangements with contractors or others, when obtained, generally provide only limited protection against product defect claims.  Due to inherent uncertainties associated with estimating unasserted claims in our business, we cannot estimate the amount of any future loss that may be attributable to unasserted product defect claims related to ready-mixed concrete we have delivered prior to December 31, 2013.
	We believe that the resolution of all litigation currently pending or threatened against us or any of our subsidiaries will not materially exceed our existing accruals for those matters.  However, because of the inherent uncertainty of litigation, there is a risk that we may have to increase our accruals for one or more claims or proceedings to which we or any of our subsidiaries is a party as more information becomes available or proceedings progress, and any such increase in accruals could have a material adverse effect on our consolidated financial condition or results of operations.  We expect in the future that we and our operating subsidiaries will, from time to time, be a party to litigation or administrative proceedings that arise in the normal course of our business.
	We are subject to federal, state and local environmental laws and regulations concerning, among other matters, air emissions and wastewater discharge. Our management believes we are in substantial compliance with applicable environmental laws and regulations. From time to time, we receive claims from federal and state environmental regulatory agencies and entities asserting that we may be in violation of environmental laws and regulations. Based on experience and the information currently available, our management does not believe that these claims will materially exceed our related accruals.  Despite compliance and experience, it is possible that we could be held liable for future charges, which might be material, but are not currently known to us or cannot be estimated by us.  In addition, changes in federal or state laws, regulations or requirements, or discovery of currently unknown conditions, could require additional expenditures.
	As permitted under Delaware law, we have agreements that provide indemnification of officers and directors for certain events or occurrences while the officer or director is or was serving at our request in such capacity. The maximum potential amount of future payments that we could be required to make under these indemnification agreements is not limited; however, we have a director and officer insurance policy that potentially limits our exposure and enables us to recover a portion of future amounts that may be paid.  As a result of the insurance policy coverage, we believe the estimated fair value of these indemnification agreements is minimal. Accordingly, we have not recorded any liabilities for these agreements as of December 31, 2013.
	We and our subsidiaries are parties to agreements that require us to provide indemnification in certain instances when we acquire businesses and real estate and in the ordinary course of business with our customers, suppliers, lessors and service providers.
	Lease Payments
	We lease certain mobile and other equipment, land, facilities, office space and other items which, in the normal course of business, are renewed or replaced by subsequent leases.  Total expense for such operating leases amounted to $11.2 million in 2013 and $13.8 million in 2012.
	Future minimum rental payments with respect to our lease obligations as of December 31, 2013, are as follows:
		Operating
		Leases
		(in millions)
	Year ending December 31:
	2014	$	8
	2015	6.7
	2016	5.7
	2017	5.4
	2018	4.4
	Thereafter	7.3
		$	37.5
	Insurance Programs
	We maintain third-party insurance coverage against certain risks.  Under certain components of our insurance program, we share the risk of loss with our insurance underwriters by maintaining high deductibles subject to aggregate annual loss limitations.  Generally, our deductible retentions per occurrence for auto, workers’ compensation and general liability insurance programs are $1.0 million, although certain of our operations are self-insured for workers’ compensation.  We fund these deductibles and record an expense for expected losses under the programs.  The expected losses are determined using a combination of our historical loss experience and subjective assessments of our future loss exposure. The estimated losses are subject to uncertainty from various sources, including changes in claims reporting patterns, claims settlement patterns, judicial decisions, legislation and economic conditions.  Although we believe that the estimated losses we have recorded are reasonable, significant differences related to the items noted above could materially affect our insurance obligations and future expense. The amount accrued for self-insurance claims was $8.6 million as of December 31, 2013, compared to $9.0 million as of December 31, 2012, which is currently classified in accrued liabilities.
	Performance Bonds
	In the normal course of business, we and our subsidiaries are contingently liable for performance under $7.7 million in performance bonds that various contractors, states and municipalities have required as of December 31, 2013. The bonds principally relate to construction contracts, reclamation obligations and licensing and permitting.  We and our subsidiaries have indemnified the underwriting insurance company against any exposure under the performance bonds. No material claims have been made against these bonds.

	EMPLOYEE BENEFIT PLANS AND MULTI-EMPLOYER PENSION PLANS
	Defined Contribution 401(k) Plan
	We maintain a defined contribution 401(k) profit sharing plan for employees meeting various employment requirements. Eligible employees may contribute amounts up to the lesser of 60% of their annual compensation or the maximum amount IRS regulations permit.  During 2013, we matched 50% of employee contributions up to a maximum of 6% of their compensation. During 2012, we matched 50% of employee contributions up to a maximum of 5% of their compensation.  We paid matching contributions of $1.0 million in each of 2013 and 2012.
	Multi-employer Pension Plans
	Several of our subsidiaries are parties to various collective bargaining agreements with labor unions having multi-year terms that expire on a staggered basis.  Under these agreements, our applicable subsidiaries pay specified wages to covered employees, observe designated workplace rules and make payments to multi-employer pension plans and employee benefit trusts rather than administering the funds on behalf of these employees. The risks of participating in these multi-employer pension plans are different from single-employer plans. Assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. If we choose to stop participating in some of these multi-employer plans, we may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability. We did not have to record a liability in fiscal 2013 or 2012 for full and partial withdrawals from any multi-employer pension plans. For additional information regarding our potential future obligations, see Note 23.
	The required disclosures and our participation in significant multi-employer pension plans are presented in the table below. The EIN/Pension Plan Number column provides the Employer Identification Number (“EIN”) and the three-digit plan number, if applicable. The Pension Protection Act zone status is based on information available from the plan or the plan’s public filings. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the orange or yellow zones are less than 80 percent funded, and plans in the green zone are at least 80 percent funded. The FIP/RP Status Pending/Implemented column indicates plans for which a financial improvement plan (“FIP”) or a rehabilitation plan (“RP”) is either pending or has been implemented. The last column lists the expiration date(s) of the collective-bargaining agreements to which the plans are subject. Our contributions did not represent more than 5% percent of total contributions to any of the significant plans shown below.

ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The consolidated financial statements consist of the accounts of U.S. Concrete, Inc. and its wholly owned subsidiaries. All significant intercompany account balances and transactions have been eliminated.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	We record as cash equivalents all highly liquid investments having maturities of three months or less at the date of purchase. Our cash equivalents may include money market accounts, certificates of deposit and commercial paper of highly rated corporate or government issuers. We classify our cash equivalents as held-to-maturity. Cash equivalents are stated at cost plus accrued interest, which approximates market value. The maximum amount placed in any one financial institution is limited in order to reduce risk. At times, our investments may be in excess of amounts insured by the Federal Deposit Insurance Corporation ("FDIC"). We have not experienced any losses on these accounts. Cash held as collateral or escrowed for contingent liabilities is included in other current and noncurrent assets based on the expected release date of the underlying obligation.
Inventories	'
	Inventories
	Inventories consist primarily of cement and other raw materials, aggregates at our pits and quarries, precast concrete products and building materials that we hold for sale or use in the ordinary course of business. Inventories are stated at the lower of cost or fair market value using the average cost and first-in, first-out methods. We reduce the carrying value of our inventories for estimated excess and obsolete inventories equal to the difference between the cost of inventory and its estimated realizable value based upon assumptions about future product demand and market conditions. Once the new cost basis is established, the value is not increased with any changes in circumstances that would indicate an increase after the remeasurement. If actual product demand or market conditions are less favorable than those projected by management, inventory write-downs may be required that could result in a material change to our consolidated results of operations or financial position.
Prepaid Expenses	'
	Prepaid Expenses
	Prepaid expenses primarily include amounts we have paid for insurance, licenses, taxes, rent and maintenance contracts. We expense or amortize all prepaid amounts as used or over the period of benefit, as applicable.
Property, Plant and Equipment, Net	'
	Property, Plant and Equipment, Net
	We state property, plant and equipment at cost and use the straight-line method to compute depreciation of these assets other than mineral deposits over the following estimated useful lives: buildings and land improvements, from 10 to 40 years; machinery and equipment, from 10 to 30 years; mixers, trucks and other vehicles, from one to 12 years; and other, from three to 10 years. We capitalize leasehold improvements on properties held under operating leases and amortize those costs over the lesser of their estimated useful lives or the applicable lease term.  We compute depletion of mineral deposits as such deposits are extracted utilizing the units-of-production method. We expense maintenance and repair costs when incurred and capitalize and depreciate expenditures for major renewals and betterments that extend the useful lives of our existing assets.  When we retire or dispose of property, plant or equipment, we remove the related cost and accumulated depreciation from our accounts and reflect any resulting gain or loss in our statements of operations.
	Impairment of Long-lived assets
	We evaluate the recoverability of our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets is measured by comparing the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. Such evaluations for impairment are significantly impacted by estimates of future prices for our products, capital needs, economic trends in the applicable construction sector and other factors.  If we consider such assets to be impaired, the impairment we recognize is measured by the amount by which the carrying amount of the assets exceeds their fair value.  Assets to be disposed of by sale are reflected at the lower of their carrying amounts, or fair values, less cost to sell. We test for impairment using a multi-tiered approach that incorporates an equal weighting to a multiple of earnings and an equal weighting to discounted estimated future cash flows.
Intangible Assets Including Goodwill	'
	Intangible Assets Including Goodwill
	Identifiable intangible assets with finite lives are amortized over their estimated useful lives. They are amortized using a straight-line approach based on the estimated useful life of each asset. Goodwill represents the amount by which the total purchase price we have paid for acquisitions exceeds our estimated fair value of the net tangible and identifiable intangible assets acquired.  Goodwill is not amortized, but is evaluated for impairment within the reporting unit on an annual basis. We generally test for intangible asset impairment in the fourth quarter of each year, because this period gives us the best visibility of the reporting units’ operating performances for the current year (seasonally, April through October are our highest revenue and production months), and our outlook for the upcoming year, since much of our customer base is finalizing operating and capital budgets during the fourth quarter.  The impairment test we use involves estimating the fair value of our reporting units and comparing the result to the reporting unit's carrying value. We estimate fair value using an equally weighted combination of discounted cash flows and multiples of revenue and EBITDA. The discounted cash flow model includes forecasts for revenue and cash flows discounted at our weighted average cost of capital. Multiples of revenue and EBITDA are calculated using the trailing twelve months results compared to the enterprise value of the Company, which is determined based on the combination of the market value of our capital stock and total outstanding debt. If the fair value exceeds the carrying value, the second step is not performed and no impairment is recorded. If however, the fair value is below the carrying value, a second step is performed to calculate the amount of the impairment by measuring the goodwill at an implied fair value. See Note 4 for further discussion of our goodwill and purchased intangible assets.
Debt Issue Costs	'
	Debt Issue Costs
	We amortize debt issue costs related to our $125.0 million asset-based revolving credit facility (the "2013 Loan Agreement"), our 8.5% Senior Secured Notes due 2018 (the "2018 Notes"), our 9.5% Senior Secured Notes due 2015 (the "2013 Notes"), and our 9.5% Convertible Secured Notes due 2015 (the "Convertible Notes") as interest expense over the scheduled maturity period of the debt. Unamortized debt issuance costs were $7.6 million and $4.2 million as of December 31, 2013 and 2012, respectively. We include unamortized debt issue costs in other assets. See Note 9 for additional information regarding our debt, and Note 10 regarding our extinguishment of debt during 2013 and 2012.
Allowance for Doubtful Accounts	'
	Allowance for Doubtful Accounts
	We maintain an allowance for accounts receivable we believe may not be collected in full. A provision for bad debt expense recorded to selling, general and administrative expenses increases the allowance.  Accounts receivable are written off when we determine the receivable will not be collected.  Accounts receivable that we write off our books decrease the allowance.  We determine the amount of bad debt expense we record each period and the resulting adequacy of the allowance at the end of each period by using a combination of historical loss experience, a customer-by-customer analysis of our accounts receivable balances each period and subjective assessments of our bad debt exposure.
Revenue and Expenses	'
	Revenue and Expenses
	We derive substantially all of our revenue from the production and delivery of ready-mixed concrete, aggregates, precast concrete products, and related building materials.  We recognize revenue, net of sales tax, when products are delivered, selling price is fixed or determinable, persuasive evidence of an arrangement exists, and collection is reasonably assured.  Amounts billed to customers for delivery costs are classified as a component of total revenues and the related delivery costs (excluding depreciation) are classified as a component of total cost of goods sold. Cost of goods sold consists primarily of product costs and operating expenses (excluding depreciation, depletion and amortization).  Operating expenses consist primarily of wages, benefits, insurance and other expenses attributable to plant operations, repairs and maintenance, and delivery costs.  Selling expenses consist primarily of sales commissions, salaries of sales managers, travel and entertainment expenses, and trade show expenses. General and administrative expenses consist primarily of executive and administrative compensation and benefits, office rent, utilities, communication and technology expenses, provision for doubtful accounts, and legal and professional fees.
Deferred Rent	'
	Deferred Rent
	We recognize escalating lease payments on a straight-line basis over the term of each respective lease with the difference between cash payment and rent expense recognized being recorded as deferred rent (included in accrued liabilities) in the accompanying consolidated balance sheets.
Insurance Programs	'
	Insurance Programs
	We maintain third-party insurance coverage against certain risks. Under our insurance programs, we share the risk of loss with our insurance underwriters by maintaining high deductibles subject to aggregate annual loss limitations.  In connection with these automobile, general liability and workers’ compensation insurance programs, we have entered into standby letters of credit agreements totaling $11.3 million and $12.2 million at December 31, 2013 and 2012, respectively.  We fund our deductibles and record an expense for losses we expect under the programs.  We determine expected losses using a combination of our historical loss experience and subjective assessments of our future loss exposure.  The estimated losses are subject to uncertainty from various sources, including changes in claim reporting patterns, claim settlement patterns, judicial decisions, legislation and economic conditions.
Income Taxes	'
	Income Taxes
	We use the liability method of accounting for income taxes. Under this method, we record deferred income taxes based on temporary differences between the financial reporting and tax bases of assets and liabilities and use enacted tax rates and laws that we expect will be in effect when we recover those assets or settle those liabilities, as the case may be, to measure those taxes.  We record a valuation allowance to reduce the deferred tax assets to the amount that is more likely than not to be realized.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Our financial instruments consist of cash and cash equivalents, trade receivables, trade payables, long-term debt, other long-term obligations, and derivative liabilities.  We consider the carrying values of cash and cash equivalents, trade receivables and trade payables to be representative of their respective fair values because of their short-term maturities or expected settlement dates.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  Estimates and assumptions that we consider significant in the preparation of our financial statements include those related to our allowance for doubtful accounts, goodwill, intangibles, valuation of derivatives, accruals for self-insurance, income taxes, the valuation of inventory and the valuation and useful lives of property, plant and equipment.
Stripping Costs	'
	Stripping Costs
	We include post-production stripping costs in the cost of inventory produced during the period as these costs are incurred. Post-production stripping costs represent stripping costs incurred after the first salable minerals are extracted from the mine.
Loss Per Share	'
	Loss Per Share
	Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period after giving effect to all potentially dilutive securities outstanding during the period. See Note 19 for additional information regarding our earnings (loss) per share.
Comprehensive Income	'
	Comprehensive Income
	Comprehensive income represents all changes in equity of an entity during the reporting period, except those resulting from investments by and distributions to stockholders. For the years ended December 31, 2013 and December 31, 2012, no differences existed between our consolidated net income and our consolidated comprehensive income.
Stock-based Compensation	'
	Stock-based Compensation
	Stock-based employee compensation cost is measured at the grant date based on the calculated fair value of the award. We recognize expense over the employee’s requisite service period, generally the vesting period of the award, or in the case of performance-based awards, over the life of the derived service period. The related excess tax benefit received upon exercise of stock options or vesting of restricted stock, if any, is reflected in the statement of cash flows as a financing activity rather than an operating activity. See Note 18 for additional information regarding our stock-based compensation plans.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (the "FASB") issued an amendment on the financial statement presentation for an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendment specifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward with certain exceptions. The guidance is effective for annual and interim reporting periods beginning after December 15, 2013. The Company's existing policies and procedures comply with the guidance, thus there will be no material impact on the consolidated financial statements upon the guidance becoming effective.
	In January 2013, the FASB issued an amendment to clarify the scope of a prior amendment issued in December 2011. The January 2013 amendment limits the December 2011 amendment's disclosure requirements regarding offsetting and related arrangements to specific derivative, borrowing, and lending transactions. Thus, certain master netting arrangements are no longer subject to the December 2011 amendment's requirements. Both the December 2011 and January 2013 amendments are effective for annual and interim reporting periods beginning on or after January 1, 2013. The Company adopted this guidance on January 1, 2013, and there was no material impact on the consolidated financial statements.
	In July 2012, the FASB issued an amendment to its indefinite-lived intangible assets impairment testing guidance to simplify how entities test for indefinite-lived intangible asset impairments. The objective of the amendment is to reduce cost and complexity by providing an entity with the option to make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test. The amendment also enhances the consistency of impairment testing guidance among long-lived asset categories by permitting an entity to assess qualitative factors to determine whether it is necessary to calculate the asset's fair value when testing an indefinite-lived intangible asset for impairment, which is equivalent to the impairment testing requirements for other long-lived assets. The amendment is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, although early adoption is permitted. The Company adopted this guidance on January 1, 2013, and there was no material impact on the consolidated financial statements. The Company completes annual impairment testing during the fourth quarter.
