Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION
	The accompanying unaudited condensed consolidated financial statements include the accounts of U.S. Concrete, Inc. and its subsidiaries (collectively, "we," "us," "our," "U.S. Concrete," or the "Company") and have been prepared by us pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") for reporting interim financial information. Some information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP") have been condensed or omitted pursuant to the SEC’s rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes in our Annual Report on Form 10-K for the year ended December 31, 2014 (the "2014 Form 10-K").  In the opinion of our management, all adjustments necessary to state fairly the information in our unaudited consolidated financial statements and to make such financial statements not misleading have been included. All adjustments are of a normal or recurring nature.  Operating results for the three months ended March 31, 2015 are not necessarily indicative of our results expected for the year ending December 31, 2015, or for any future period.
	The preparation of financial statements and accompanying notes in conformity with U.S. GAAP requires management to make estimates and assumptions 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 revenue and expenses during the reporting period.  Actual results could differ from those estimates. Estimates and assumptions that we consider critical and that involve complex judgments in the preparation of our financial statements include those related to our goodwill, accruals for self-insurance, income taxes, the valuation of long-lived assets, and the valuation of derivative instruments.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS AND SIGNIFICANT ACCOUNTING POLICIES	RECENT ACCOUNTING PRONOUNCEMENTS AND SIGNIFICANT ACCOUNTING POLICIES
	In April 2014, the Financial Accounting Standards Board (the "FASB") issued an amendment on reporting discontinued operations and disclosures of disposals of components of an entity. Specifically, the amendment revises the definition of a discontinued operation, expands disclosure requirements for transactions that meet the definition of a discontinued operation and requires entities to disclose additional information about individually significant components that are disposed of or held for sale and do not qualify as discontinued operations. Additionally, entities will be required to reclassify assets and liabilities of a discontinued operation for all comparative periods presented in the statement of financial position and to separately present certain information related to the operating and investing cash flows of the discontinued operation, for all comparative periods, in the statement of cash flows. The amendment is effective for annual and interim periods beginning after December 15, 2014 and is to be adopted on a prospective basis for all disposals (except disposals classified as held for sale prior to the adoption date) or components initially classified as held for sale in periods beginning on or after the adoption date. We adopted this guidance effective January 1, 2015, and there was no material impact on our consolidated financial statements or results of operations.
	For a description of our significant accounting policies, see Note 1 of the condensed consolidated financial statements in our 2014 Form 10-K.

ACQUISITIONS AND DISPOSITIONS	ACQUISITIONS AND DISPOSITIONS
	2015 Acquisition
	On February 24, 2015, we acquired the equity of Right Away Redy Mix, Inc. ("Right Away"), in Oakland, California. The purchase price was $18.0 million in cash, plus closing adjustments of $0.9 million, plus potential future earn-out payments of up to $6.0 million based on the achievement of certain defined annual volume thresholds over a six-year period (the "Right Away Earn-out"). The acquisition included four ready-mixed concrete facilities, 49 mixer trucks and a fleet of transfer trucks used to transport cement and aggregates. The purchase of these assets expanded our business in our existing northern California market. The fair value of the assets acquired and liabilities assumed in the Right Away acquisition is preliminary and remains subject to adjustments, including, but not limited to, adjustments related to working capital, the fair value of the Right Away Earn-out, identifiable intangible assets, and property, plant and equipment.
	The following table presents the consideration paid for Right Away and the allocation of these amounts to the net tangible and intangible assets acquired and liabilities assumed based on the estimated fair values as of the respective acquisition date (in thousands).
		Right Away
	Cash	$	928
	Accounts receivable	1,832
	Inventory	348
	Other current assets	275
	Property, plant and equipment	10,464
	Total assets acquired	$	13,847
	Current liabilities	1,471
	Long-term liabilities	7
	Total liabilities assumed	$	1,478
	Goodwill	6,493
	Net assets acquired for cash consideration	$	18,862
	These allocations require the significant use of estimates and are based on information that was available to management at the time these condensed consolidated financial statements were prepared. We utilized recognized valuation techniques, including the income approach, sales approach, and cost approach, to value the net assets acquired. Any changes to the purchase price allocations will be made as soon as practical, but no later than one year from the acquisition date.
	The fair value of the acquired receivables is $1.8 million, with a gross contractual amount of $2.2 million. We do not expect to collect $0.4 million of the acquired receivables.
	The goodwill ascribed to the Right Away acquisition is related to the synergies we expect to achieve with expansion in the East San Francisco Bay area of the northern California market in which we already operate. We do not expect the goodwill to be deductible for tax purposes. The goodwill relates to our ready-mixed concrete reportable segment. See Note 12 for additional information regarding income taxes.
	2014 Acquisitions
	On October 20, 2014, we acquired the assets of Custom-Crete ("Custom-Crete"), with operations in Dallas / Fort Worth, Houston, San Antonio, and Austin, Texas from Oldcastle Architectural, Inc., a wholly owned subsidiary of CRH plc ("Oldcastle Architectural") for $37.4 million in cash, less final working capital adjustments of $1.6 million. The fair value of the assets acquired and liabilities assumed in the Custom-Crete acquisition is preliminary and remains subject to potential adjustments, including, but not limited to, adjustments related to an expected subsequent payment to Oldcastle Architectural for land that is pending the division of certain shared properties.
	On December 5, 2014, we acquired the assets of Mobile-Crete of South Texas, LLC and Scofield Construction Services, LLC (collectively, "Mobile-Crete") with operations in San Antonio, Austin, and south Texas for $21.5 million in cash, plus potential earn-out payments of up to $3.0 million in cash (the "Mobile-Crete Earn-out"). The earn-out payments of up to $1.5 million in each of the next two years are tied to the applicable year's average daily closing price of West Texas Intermediate Crude Oil reaching certain predetermined levels. The fair value of the assets acquired and liabilities assumed in the Mobile-Crete acquisition is preliminary and remains subject to adjustments, including, but not limited to, adjustments related to working capital, the fair value of the Mobile-Crete Earn-out, identifiable intangible assets, and property, plant and equipment.
	The Custom-Crete and Mobile-Crete acquisitions included 16 volumetric ready-mixed concrete facilities and 109 volumetric ready-mixed concrete trucks. The addition of these operations expanded our presence into all of the major metropolitan markets in Texas and provided us with the capability to deliver ready-mixed concrete to our customers via on-site batching and mixing to customer specifications.
	On October 20, 2014, we acquired the equity of New York Sand and Stone, LLC ("NYSS") for $15.2 million in cash. The NYSS acquisition included leases to operate two aggregate distribution terminals in New York. These terminals allow us to deliver raw materials more efficiently to our New Jersey / New York market. The fair value of the assets acquired and liabilities assumed in the NYSS acquisition is preliminary and remains subject to potential adjustments, including, but not limited to, working capital adjustments.
	During the year ended December 31, 2014, we also completed six other acquisitions comprised of seven ready-mixed concrete plants and related assets in our New York and west Texas markets. The aggregate consideration paid consisted of $15.5 million in cash and $1.1 million in promissory notes. The acquisition of these assets expanded our business in our existing markets. The fair values of the assets acquired and liabilities assumed in these six ready-mixed concrete acquisitions are final.
	We have made changes to the preliminary purchase price allocations for the 2014 acquisitions during the first quarter of 2015 primarily related to fair value estimates of assets acquired and liabilities assumed for Mobile-Crete, working capital adjustments for Custom-Crete and NYSS, and changes in the valuation of intangible assets for three of the six acquisitions included in "All Other" in the table below. The following table presents the allocation of the consideration paid for the 2014 acquisitions to the net tangible and intangible assets acquired and liabilities assumed based on the estimated fair values as of the respective acquisition dates (in thousands).

	-4	Consideration paid for all other acquisitions includes $1.1 million of notes payable to previous owners.
	-5	The fair value of the acquired receivables approximates the gross contractual amounts as of the respective acquisition dates.
	These allocations require the significant use of estimates and are based on information that was available to management at the time these consolidated financial statements were prepared. We utilized recognized valuation techniques, including the income approach, sales approach, and cost approach, to value the net assets acquired. Any changes to the purchase price allocations will be made as soon as practical, but no later than one year from the respective acquisition dates.
	Acquired intangible assets in 2014 of $19.4 million consisted of customer relationships, trade names, non-compete agreements, and leasehold interests. The amortization period of these intangible assets ranges from two years to 11.67 years. These intangible assets exclude identifiable intangible assets from the Mobile-Crete and Right Away acquisitions as management has not yet completed the valuations. The major classes of intangible assets acquired in the 2014 acquisitions were as follows (in thousands):
		Weighted Average Amortization Period (In Years)		Intangible Assets Acquired In 2014 Acquisitions
	Customer relationships	8.82		$	8,655
	Trade name	10		2,900
	Non-compete agreements	4.81		4,427
	Leasehold interests	9.79		3,382
	Total			$	19,364
	We recorded $0.7 million of amortization expense related to these intangible assets during the three months ended March 31, 2015. The estimated future aggregate amortization expense of intangible assets from the 2014 acquisitions as of March 31, 2015 is set forth below (in thousands):
		Year Ending December 31,
	2015 (remainder of the year)	$	1,993
	2016	2,652
	2017	2,565
	2018	2,538
	2019	2,138
	Thereafter	6,234
	Total	$	18,120
	The goodwill ascribed to each of these acquisitions is related to the synergies we expect to achieve with expansion in the markets in which we already operate as well as entry into new metropolitan areas of our existing geographic markets. We expect the goodwill to be deductible for tax purposes. The goodwill relates to our ready-mixed concrete reportable segment, with the exception of the NYSS acquisition, which relates to our other non-reportable segments. See Note 12 for additional information regarding income taxes.
	Actual and Pro Forma Impact of Acquisitions
	We recorded approximately $21.8 million of revenue and less than $0.1 million of income from operations in our condensed consolidated statements of operations for the quarter ended March 31, 2015 related to the Right Away acquisition and the 2014 acquisitions following their respective acquisition dates. We recorded approximately $0.2 million of revenue and less than $0.1 million of loss from operations in our condensed consolidated statement of operations for the quarter ended March 31, 2014 related to the 2014 acquisitions following their respective acquisition dates.
The unaudited pro forma information presented below reflects the combined financial results for all of the acquisitions completed during 2014 and the first quarter of 2015, excluding three of the six acquisitions that are included in the caption "All Other" in the table captioned "2014 Acquisitions" above, as historical financial results for these operations were impractical to obtain from the former owners. We estimate that revenue and income from operations for these three acquisitions in total would have been approximately $0.9 million and less than $0.1 million, respectively, for the three months ended March 31, 2014. All other acquisitions have been included and represent our estimate of the results for the three months ended March 31, 2015 and 2014 as if the 2014 acquisitions had been completed on January 1, 2013 and the Right Away acquisition had been completed on January 1, 2014 (in thousands, except per share information):
	For The Three Months Ended March 31,
	(unaudited)
	2015				2014
Revenue from continuing operations	$	174,066			$	172,507
Net loss	$	(9,961	)		$	(223	)
Loss per share, basic and diluted	$	(0.73	)		$	(0.02	)
The above pro forma results are unaudited and were prepared based on the historical GAAP results of the Company and the historical results of the seven acquired companies for which financial information was available, based on data provided by the former owners. These results are not necessarily indicative of what the Company's actual results would have been had the 2014 acquisitions occurred on January 1, 2013 and the Right Away acquisition occurred on January 1, 2014.
The unaudited pro forma net loss and net loss per share amounts above reflect the following adjustments: (1) inclusion of an additional $0.6 million in amortization of intangibles for the quarter ended March 31, 2014 and (2) exclusion of $0.4 million of legal and professional fees incurred by the Company during the three months ended March 31, 2015 related to the acquisitions. As the purchase price allocation for Mobile-Crete and Right Away are still preliminary and fair values for the related intangible assets have not been determined, no amortization on these intangible assets is included in the pro forma results. We applied the same effective tax rate to calculate our pro forma net loss as the effective rate we applied to calculate our reported net loss for each of the three months ended March 31, 2015 and 2014 (see Note 17 to our 2014 Form 10-K regarding our effective tax rate). 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.
Sale of Pennsylvania Precast Operations
On January 30, 2014, our Board of Directors (the "Board") approved the sale of our one remaining precast concrete operation in Pennsylvania, as this business no longer fits our goal of becoming the preeminent supplier of ready-mixed concrete in the United States. As such, the related assets and liabilities have been classified as held for sale effective with the first quarter of 2014. During the first quarter of 2014, we engaged a broker to actively pursue potential buyers. We continue to evaluate proposals from buyers for this operation and expect any transaction would close during the first half of 2015. The results of operations for this business have been included in discontinued operations for the periods presented. Listed below are the major classes of assets and liabilities expected to be sold as part of any transaction that are included in held for sale captions on the accompanying condensed consolidated balance sheets as of March 31, 2015 (in thousands):
		31-Mar-15
Assets held for sale:
Trade accounts receivable, net		$	2,276
Inventories		608
Other current assets		788
Property, plant and equipment, net		851
Total assets held for sale		$	4,523
Liabilities held for sale:
Accounts payable		$	551
Accrued liabilities		719
Total liabilities held for sale		$	1,270
Purchase of Bode Gravel and Bode Concrete Equity Interests
In accordance with the terms of the 2012 Bode Gravel Co. and Bode Concrete LLC purchase agreement, we are required to make earn-out payments (the "Bode Earn-out"), which are contingent upon reaching negotiated volume hurdles and had an aggregate present value of up to $7.0 million, as of October 30, 2012, the acquisition date. The Bode Earn-out is payable in cash over a six-year period. To date, we have made two Bode Earn-out payments of $2.3 million each in the first quarters of 2014 and 2015.
Sale of California Precast Operations
In March 2014, we completed the sale of our remaining owned assets related to our California precast operations. We sold land and a building for net proceeds of $1.5 million in cash and recorded a gain on the transaction of $0.6 million. The gain is included in discontinued operations in the accompanying condensed consolidated statements of operations for the three months ended March 31, 2014.

	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 (the "2018 Notes"). We used a portion of the net proceeds from the 2018 Notes to repay all of our outstanding borrowings under the Revolving Facility (as defined below) and to redeem all $61.1 million of our outstanding 9.5% senior secured notes due 2015 that were issued in 2013 (the "2013 Notes").
	The 2018 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, which commenced 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 pro forma 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 direct and indirect wholly owned subsidiaries. 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 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 expiring 2018
	On October 29, 2013, we entered into a First Amended and Restated Loan and Security Agreement, as subsequently amended, (the "2013 Loan Agreement") with certain financial institutions named therein, as lenders (the "Lenders"), and Bank of America, N.A., as agent and sole lead arranger (the "Administrative Agent"), which amended and restated our existing credit agreement and provides us with an asset-based revolving credit facility (the "Revolving Facility"). Under the terms of the 2013 Loan Agreement, the maximum credit availability under our Revolving Facility is $175.0 million, subject to a borrowing base calculation as described below. The 2013 Loan Agreement expires on October 2, 2018. As of March 31, 2015, we had no outstanding borrowings and $11.3 million of undrawn standby letters of credit under the 2013 Loan Agreement.
	Our maximum credit availability under the 2013 Loan Agreement varies from time to time and is determined by calculating a borrowing base, which is based on 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 2013 Loan Agreement at March 31, 2015 decreased to $105.7 million from $109.8 million at December 31, 2014. The 2013 Loan Agreement also contains a provision for discretionary over-advances and involuntary protective advances by the 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-day 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 letters of credit, and customary charges associated with the issuance and administration of letters of credit.  Among other fees, we pay 0.25% or 0.375% per annum (due monthly) on the aggregate unused revolving commitments under the Revolving Facility. 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 lessor of the Revolving Facility minus the LC Reserve, the Senior Notes Availability Reserve, and the Tax Reserve, all 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) $40.0 million 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; repurchase stock; 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 12 calendar months, as determined in accordance with the 2013 Loan Agreement.  For the trailing 12-month period ended March 31, 2015, our fixed charge coverage ratio was 2.24 to 1.0. As of March 31, 2015, the Company was 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, a change of control of the Company, 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 the 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 on a first-priority basis.
	Convertible Notes due 2015
	On August 31, 2010, we issued $55.0 million aggregate principal amount of 9.5% Convertible Notes due on August 31, 2015 (the "Convertible Notes"). During 2013, we exchanged $48.5 million of Convertible Notes for $61.1 million aggregate principal amount of 2013 Notes and $6.4 million of Convertible Notes for 0.6 million shares of common stock. The remaining Convertible Notes no longer include a conversion feature or accrue interest. As of March 31, 2015, $0.1 million of aggregate principal amount of Convertible Notes remain outstanding.
	Capital Leases and Other Financing
	In 2013, we entered into master leasing agreements with GE Capital Commercial, Inc. and Capital One Equipment Finance Corporation to provide up to $10.0 million in total lease commitments for mixer trucks and other machinery and equipment. As of March 31, 2015, we have utilized $7.1 million of these lease commitments. Interest on these lease commitments accrues at fixed annual rates ranging from 4.15% to 4.80%, and payments are due monthly for a term of five years. The lease terms include one dollar buyout options at the end of the lease terms. Accordingly, these financings have been classified as capital leases.
	From 2013 through the first quarter of 2015, we signed a series of promissory notes with Daimler Truck Financial for the purchase of mixer trucks totaling $14.3 million aggregate principal, with fixed annual interest rates ranging from 2.99% to 3.18%, payable monthly for a term of five years. Also, from 2014 through the first quarter of 2015, we entered into five lease agreements with SunTrust Equipment Finance and Leasing Corporation for a total commitment of $1.9 million, with fixed annual interest rates ranging from 3.49% to 3.75%, payable monthly for terms ranging from four to five years. The lease terms include one dollar buyout options at the end of the lease terms. Accordingly, these financings have been classified as capital leases.
	The current portion of capital leases included in current maturities of long-term debt was $1.7 million as of March 31, 2015 and $1.6 million as of December 31, 2014.
	As of March 31, 2015, we had five promissory notes outstanding that were issued primarily in connection with acquisitions completed between October 2010 and August 2014 in an aggregate principal amount of $4.0 million. These promissory notes are payable either monthly or annually over two to nine years, with annual effective interest rates ranging from 3.49% to 5.00%. In January 2015, we entered into an 11 month financing agreement for an aggregate principal amount of $1.5 million for certain of our third-party insurance policies, which is payable monthly with a fixed annual interest rate of 4.09%.
	The weighted average interest rate of our capital leases and other financings was 3.49% as of March 31, 2015 and December 31, 2014. We made cash principal payments associated with our capital leases and other financings totaling $1.6 million and $1.0 million during the three months ended March 31, 2015 and 2014, respectively.

	On August 31, 2010, we issued warrants to acquire common stock (the “Warrants”) 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.  The Warrants were issued to holders of our predecessor common stock pro rata based on a holder’s stock ownership. The fair value of these Warrants have been included in derivative liabilities on the accompanying condensed consolidated balance sheets (see Note 10) and are recorded at their fair value (see Note 11). The Warrants are classified as a current liability on the accompanying condensed consolidated balance sheets as they can be exercised by the holders at any time.

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 assets and liabilities within the fair value hierarchy.
	The following tables present our fair value hierarchy for liabilities measured at fair value on a recurring basis (in thousands):
		March 31, 2015

	-1	Represents the fair value of the Warrants (see Note 9).
	-2	Represents the fair value of the Bode Earn-out (see Note 3). 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 were capped at a fair value of $3.5 million and $5.3 million as of March 31, 2015 and December 31, 2014.
	-3	The fair values of the Right Away Earn-out and the Mobile-Crete Earn-out are pending valuation, which will be completed as soon as practical, but no later than one year from the respective acquisition dates.
	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, we modeled inputs based upon similar observable inputs. The key inputs in determining our derivative liabilities include our stock price, stock price volatility, and risk free interest rates.
	A reconciliation of the changes in Level 3 fair value measurements from December 31, 2014 to March 31, 2015 is provided below (in thousands):
		Warrants		Bode Earn-Out

	Payment on Bode Earn-out	—		(1,864		)
	Balance at March 31, 2015	$	36,745	$	3,480
	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 fair value of our 2018 Notes, estimated based on broker/dealer quoted market prices, was $211.0 million as of March 31, 2015. The carrying value of outstanding amounts under our 2013 Loan Agreement approximates fair value due to the floating interest rate. The fair value of our remaining Convertible Notes was approximately $0.1 million at March 31, 2015 and December 31, 2014.

	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 March 31, 2015 and December 31, 2014 for other deferred tax assets because of uncertainty regarding their ultimate realization.  Our total net deferred tax liability was approximately $4.5 million as of March 31, 2015 and December 31, 2014. We made income tax payments of approximately $0.3 million and less than $0.1 million during the three months ended March 31, 2015 and 2014.
	Despite income in 2014 and projected future taxable income, as of March 31, 2015, we remain in a three year cumulative loss position and will, therefore, continue to record a valuation allowance on all U.S. deferred tax assets. The cumulative loss position is considered a significant source of negative evidence and limits our ability to consider other subjective evidence such as our projections for future growth when assessing the need for a deferred tax valuation allowance. Our cumulative loss position will continue to change as a result of historical and current earnings performance. This change, among other factors, may cause us to reduce our valuation allowance on deferred tax assets in the future. Any adjustment to our valuation allowance would impact our income tax expense in the period that our evaluation changes.
	In accordance with U.S. GAAP, intra-period tax allocation provisions require allocation of a tax expense to continuing operations due to current income from discontinued operations. We recorded a tax benefit of $0.1 million and tax expense of less than $0.1 million in loss from continuing operations for the three months ended March 31, 2015 and 2014. We recorded a tax expense of less than $0.1 million and $0.2 million allocated to discontinued operations for the three months ended March 31, 2015 and 2014. The intra-period tax allocation between the results from continuing operations and discontinued operations in the three months ended March 31, 2015 and 2014 nets to $0.
	We underwent a change in ownership for purposes of Section 382 of the Internal Revenue Code of 1986, as amended, as a result of the consummation of our plan of reorganization on August 31, 2010.  As a result, the amount of our pre-change net operating losses (“NOLs”) 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 of reorganization.  The ownership change and the resulting annual limitation on the use of NOLs 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 NOLs available to offset taxable income in a specific year may result in the payment of income taxes before all NOLs have been utilized.  Additionally, a subsequent ownership change may result in further limitations on our ability to utilize existing NOLs and other tax attributes.

	Common Stock and Preferred Stock
	The following table presents information regarding our common stock (in thousands):
		March 31, 2015	December 31, 2014
	Shares authorized	100,000	100,000
	Shares outstanding at end of period	13,970	13,978
	Shares held in treasury	709	697
	Under our amended and restated certificate of incorporation, we are authorized to issue 100.0 million shares of common stock, par value $0.001 per share, and 10.0 million shares of preferred stock, par value $0.001 per share. The preferred stock may be issued from time to time in one or more series upon authorization by the Board. The Board, without further approval of the stockholders, is authorized to fix the dividend rights and terms, conversion rights, voting rights, redemption rights and terms, liquidation preferences, and any other rights, preferences and restrictions applicable to each series of the preferred stock.  The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, adversely affect the voting power of the holders of the common stock and, under certain circumstances, make it more difficult for a third party to gain control of us, discourage bids for our common stock at a premium or otherwise affect the market price of our common stock. There was no preferred stock issued or outstanding as of March 31, 2015 or December 31, 2014.
	Share Repurchase Program
	In May 2014, our Board authorized a program to repurchase up to $50.0 million of our outstanding common stock (the "Share Repurchase Program") until the earlier of March 31, 2017, or a determination by the Board to discontinue the Share Repurchase Program. We made no repurchases of our common stock during the three months ended March 31, 2015 under the Share Repurchase Program.
	Treasury Stock
	Employees may elect to satisfy their tax obligations on the vesting of their restricted stock by having the required tax payments withheld based on a number of vested shares having an aggregate value on the date of vesting equal to the tax obligation.  As a result of such employee elections, we withheld approximately 13,000 shares with a total value of $0.4 million during the three months ended March 31, 2015. We withheld approximately 1,200 shares with a total value of less than $0.1 million during the three months ended March 31, 2014. We accounted for the withholding of these shares as treasury stock.

NET EARNINGS (LOSS) PER SHARE	NET EARNINGS (LOSS) PER SHARE
	Basic earnings (loss) per share is computed by dividing net earnings (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is computed by dividing net earnings (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.
	For the three months ended March 31, 2015 and 2014, our potentially dilutive shares include the shares underlying our restricted stock, restricted stock units, stock options, and Warrants. The following table shows the type and number (in thousands) of potentially dilutive shares excluded from the diluted earnings (loss) per share calculations for the periods presented as their effect would have been anti-dilutive or they have not met their performance target:

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	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 from 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 contributing employers in the plans has an effect on each of the other contributing employers, 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 31, 2015, 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 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 claims in our business, we cannot estimate the amount of any future loss that may be attributable to product defect claims related to ready-mixed concrete we have delivered prior to March 31, 2015.
	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 March 31, 2015.
	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.
	Insurance Programs
	We maintain third-party insurance coverage against certain risks in amounts we believe are reasonable.  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.  We determine the 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 claims reporting patterns, claims settlement patterns, judicial decisions, legislation and economic conditions.  Although we believe the estimated losses we have recorded are reasonable, significant differences related to the items we have noted above could materially affect our insurance obligations and future expense. The amount accrued for estimated losses was $9.6 million as of March 31, 2015, compared to $9.5 million as of December 31, 2014, which are classified in accrued liabilities in our condensed consolidated balance sheets.
	Performance Bonds
	In the normal course of business, we are contingently liable for performance under $8.3 million in performance bonds that various contractors, states and municipalities have required as of March 31, 2015. The bonds principally relate to construction contracts, reclamation obligations and licensing and permitting.  We have indemnified the underwriting insurance company against any exposure under the performance bonds. No material claims have been made against these bonds as of March 31, 2015.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION
	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, northern California, New Jersey, New York, Washington, D.C. and Oklahoma. With the acquisition of the volumetric ready-mixed concrete businesses during the fourth quarter of 2014 (see Note 3), we have further expanded our presence in Texas into all of its major metropolitan markets. 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 an aggregate distribution operation. The financial results of the acquisitions completed in the 2015 first quarter and 2014 have been included in their respective reportable segment or in other products as of their respective acquisition dates.
	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 and
	•	corporate officer severance expense.
	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, operating 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.
	The following tables set forth certain financial information relating to our continuing operations by reportable segment (in thousands):

SUBSEQUENT EVENTS	SUBSEQUENT EVENT
	On April 2, 2015, we announced that we completed the acquisition of all of the issued and outstanding equity interests of Ferrara Bros. Building Materials Corp. ("Ferrara Bros."), in New York, New York. We acquired the equity of Ferrara Bros. for $45.0 million in cash, 0.4 million shares of our common stock, calculated in accordance with the terms of the share purchase agreement ("SPA") dated April 1, 2015, and valued at approximately $15.1 million on the date of issuance, plus potential incentive awards in the form of equity of up to $35.0 million based on the achievement of certain EBITDA thresholds, as defined in the SPA, over a four-year period beginning in 2017. We funded the purchase through a combination of cash on hand and borrowings on our Revolving Credit Facility. Ferrara Bros. operates six ready-mixed concrete plants at its four facilities in New York and New Jersey and a fleet of 89 mixer trucks. The acquisition expands our presence in the New York metropolitan market and will allow us to more effectively serve construction projects in Manhattan. We will prepare the preliminary purchase price allocation for this acquisition as soon as practical, but no later than one year from the acquisition date.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements include the accounts of U.S. Concrete, Inc. and its subsidiaries (collectively, "we," "us," "our," "U.S. Concrete," or the "Company") and have been prepared by us pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") for reporting interim financial information. Some information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP") have been condensed or omitted pursuant to the SEC’s rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes in our Annual Report on Form 10-K for the year ended December 31, 2014 (the "2014 Form 10-K").  In the opinion of our management, all adjustments necessary to state fairly the information in our unaudited consolidated financial statements and to make such financial statements not misleading have been included. All adjustments are of a normal or recurring nature.  Operating results for the three months ended March 31, 2015 are not necessarily indicative of our results expected for the year ending December 31, 2015, or for any future period.
Use of Estimates	The preparation of financial statements and accompanying notes in conformity with U.S. GAAP requires management to make estimates and assumptions 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 revenue and expenses during the reporting period.  Actual results could differ from those estimates. Estimates and assumptions that we consider critical and that involve complex judgments in the preparation of our financial statements include those related to our goodwill, accruals for self-insurance, income taxes, the valuation of long-lived assets, and the valuation of derivative instruments.
Recent Accounting Pronouncements and Significant Accounting Policies	In April 2014, the Financial Accounting Standards Board (the "FASB") issued an amendment on reporting discontinued operations and disclosures of disposals of components of an entity. Specifically, the amendment revises the definition of a discontinued operation, expands disclosure requirements for transactions that meet the definition of a discontinued operation and requires entities to disclose additional information about individually significant components that are disposed of or held for sale and do not qualify as discontinued operations. Additionally, entities will be required to reclassify assets and liabilities of a discontinued operation for all comparative periods presented in the statement of financial position and to separately present certain information related to the operating and investing cash flows of the discontinued operation, for all comparative periods, in the statement of cash flows. The amendment is effective for annual and interim periods beginning after December 15, 2014 and is to be adopted on a prospective basis for all disposals (except disposals classified as held for sale prior to the adoption date) or components initially classified as held for sale in periods beginning on or after the adoption date. We adopted this guidance effective January 1, 2015, and there was no material impact on our consolidated financial statements or results of operations.
