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," the "Company," or "U.S. Concrete") and have been prepared 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, 2017 (the " 2017 Form 10-K"). In the opinion of our management, all material adjustments necessary to state fairly the information in our unaudited condensed consolidated financial statements have been included. All adjustments are of a normal or recurring nature. All amounts are presented in United States dollars, unless otherwise noted. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. The preparation of financial statements and accompanying notes in conformity with 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 revenue 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, business combinations, goodwill, intangibles, valuation of contingent consideration, accruals for self-insurance programs, income taxes, the valuation of inventory and the valuation and useful lives of property, plant and equipment.

Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS AND SIGNIFICANT ACCOUNTING POLICIES	RECENT ACCOUNTING PRONOUNCEMENTS AND SIGNIFICANT ACCOUNTING POLICIES Standards/Updates Adopted This Quarter Revenue Recognition. In May 2014, the FASB issued guidance that outlines a single comprehensive model for accounting for revenue arising from contracts with customers, which supersedes most of the existing revenue recognition guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and also requires certain additional disclosures. We adopted this guidance and related amendments as of January 1, 2018, applying the modified retrospective transition approach to all contracts. Adoption of the new guidance did not result in changes in the amount of revenue recognized or the timing of when such revenue is recognized. Clarification of the Definition of a Business in Business Combinations. In January 2017, the FASB issued an update under business combinations in an effort to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or as business combinations. The amendments in this update provide a screen to determine when a set of assets is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. The adoption of this standard did not have a material impact on our financial condition and results of operations. Classification of Certain Cash Receipts and Cash Payments. In August 2016, the FASB issued guidance to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. Adoption of this standard did not result in any material changes to our statements of cash flows. Standards/Updates Not Yet Adopted Lease Accounting. In February 2016, the FASB issued an amendment related to leases intended to increase transparency and comparability among organizations by reorganizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, lessees will be required to recognize a right-of-use asset and a lease liability, measured on a discounted basis, at the commencement date for all leases with terms greater than twelve months. Additionally, this guidance will require disclosures to help investors and other financial statement users to better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. We expect to adopt the guidance using a modified retrospective transition approach. This guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual periods. We are currently evaluating the potential impact on our financial position and results of operations upon adoption of this guidance. This guidance will result in our existing operating leases, for certain real estate and equipment, to be recognized on our balance sheet. We will further analyze our lease arrangements as we complete our assessment and implementation of this new guidance. The evaluation process will include reviewing all forms of leases, performing a completeness assessment over the lease population, analyzing the practical expedients and assessing the need to make any changes to our lease accounting technology system in order to determine the best implementation strategy. For a description of our significant accounting policies, see Note 1 of the consolidated financial statements in our 2017 Form 10-K.

REVENUE

REVENUE	3 Months Ended
	Mar. 31, 2018
Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE We derive substantially all of our revenue from the production and delivery of ready-mixed concrete, aggregates and related building materials. Revenue from the sale of these products is recognized when there is persuasive evidence of an arrangement and control passes to the customer, which generally occurs at the point in time when products are delivered. We do not deliver product unless we have an order or other documentation authorizing delivery to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. Sales and other taxes we collect concurrently with revenue-producing activities are excluded from revenue. Incidental items, such as mix formulation and testing services that are immaterial in the context of the revenue contract and completed in close proximity to the revenue-producing activities, are recorded within cost of goods sold as incurred. We generally do not provide post-delivery services, such as paving or finishing. Customer dispute costs are recorded as a reduction of revenue at the end of each period and are estimated by using a combination of historical customer experience and a customer-by-customer analysis. Amounts billed to customers for delivery costs are classified as a component of total revenue. Our payment terms vary by the type and location of our customer and the products offered. The term between invoicing and when payment is due is not significant. As permitted under U.S. GAAP, we have elected not to assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment by the customer and the transfer of the promised goods to the customer will be one year or less. See Note 12 for disaggregation of revenue by segment and product as we believe that best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. We do not have any customer contracts that meet the definition of unsatisfied performance obligations in accordance with U.S. GAAP.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS The accounting for business combinations requires the significant use of estimates and is based on information that was available to management at the time these condensed consolidated financial statements were prepared. The estimates used for determining the fair value of certain liabilities related to acquisitions are considered Level 3 inputs (as defined in Note 8 ). We utilized recognized valuation techniques, including the income approach, sales approach, and cost approach to value the net assets acquired. See Note 8 for additional information related to contingent consideration obligations, including maximum payout amounts and how the fair value was estimated. Any changes to the provisional business combination accounting will be made as soon as practical, but no later than one year from the respective acquisition dates. 2018 Acquisitions We completed three acquisitions during the three months ended March 31, 2018 that expanded our ready-mixed concrete operations in the Atlantic Region (which we define to include New York, New Jersey, Washington D.C. and Pennsylvania), and expanded our ready-mixed concrete and aggregate products operations in West Texas. The aggregate fair value consideration for these acquisitions, which were all accounted for as business combinations, was $60.8 million . The acquisitions included the assets and certain liabilities of the following: • On Time Ready Mix, Inc. (" On Time ") located in Flushing, New York on January 10, 2018 ; • Cutrell Trucking, LLC., Dumas Concrete, LLC., Pampa Concrete Co., Inc., Panhandle Concrete, LLC., Texas Sand & Gravel Co., Inc. (collectively " Golden Spread ") located in Amarillo, Texas on March 2, 2018 ; and • One individually immaterial ready-mixed concrete operation in our Atlantic Region on March 5, 2018. The aggregate fair value consideration for these three acquisitions, included $ 59.9 million in cash and fair value contingent consideration of $ 0.9 million . We funded the cash portion of the 2018 acquisitions through a combination of cash on hand and borrowings under our Revolving Facility (as defined in Note 7 ). The combined assets acquired through these 2018 acquisitions included 140 mixer trucks, 19 ready-mix concrete plants and one aggregates facility. During the three months ended March 31, 2018 , we incurred $0.5 million of transaction costs to effect the 2018 acquisitions, which are included in selling and general administrative expenses in our condensed consolidated statements of operations. Our accounting for the 2018 business combinations is preliminary. We expect to record adjustments as we accumulate information needed to estimate the fair value of assets acquired and liabilities assumed, including working capital balances, estimated fair value of identifiable intangible assets, property, plant and equipment, total consideration and goodwill. The following table presents the total consideration for the 2018 acquisitions and the preliminary amounts related to the assets acquired and liabilities assumed based on the estimated fair values as of the respective acquisition dates (in thousands): 2018 Acquisitions Inventory $ 674 Other current assets 77 Property, plant and equipment 30,287 Definite-lived intangible assets 13,125 Total assets acquired 44,163 Total liabilities assumed 153 Goodwill 16,830 Total consideration (fair value) (1) $ 60,840 (1) Included $0.9 million of contingent consideration. 2017 Acquisitions We completed eight acquisitions during 2017 that expanded our ready-mixed concrete and aggregate products operations in our Atlantic Region, expanded our ready-mixed concrete operations in Northern California and facilitated vertical integration on the West Coast. The aggregate fair value consideration for these acquisitions, which were all accounted for as business combinations, was $327.9 million . The acquisitions included the assets and certain liabilities of the following: • Corbett Aggregate Companies, LLC. (" Corbett ") located in Quinton, New Jersey on April 7, 2017 ; • Harbor Ready-Mix (" Harbor ") located in Redwood City, California on September 29, 2017 ; • A-1 Materials, Inc. (" A-1 ”) and L.C. Frey Company, Inc. ("Frey") (collectively “A-1/Frey”) located in San Carlos, California on September 29, 2017 ; • Action Supply Co., Inc. (" Action Supply ") located in Philadelphia, Pennsylvania on September 29, 2017 ; • Polaris Materials Corporation (" Polaris ") located in British Columbia, Canada on November 17, 2017 ; and • Three individually immaterial acquisitions in December 2017 consisting of two ready-mixed concrete operations and a software company. The aggregate fair value consideration for these eight acquisitions, included $298.4 million in cash, $5.5 million in payments deferred over a four -year period, and fair value contingent consideration of $24.0 million . The combined assets acquired through these 2017 acquisitions included 409 acres of land, two aggregate facilities with approximately 130 million tons of proven aggregates reserves, 51 mixer trucks, seven ready-mix concrete plants and four aggregates distribution terminals. We funded the cash portion of the acquisitions through a combination of cash on hand and borrowings under our Revolving Facility (as defined in Note 7 ). Prior to the completion of the Polaris acquisition, we received two promissory notes from Polaris aggregating $18.1 million Canadian dollars, which were subsequently reclassified as intercompany loans upon completion of the acquisition and have been eliminated from our consolidated balance sheet. During the three months ended March 31, 2017 , we incurred $0.2 million of transaction costs to effect the 2017 acquisitions, which are included in selling and general administrative expenses in our condensed consolidated statements of operations. Our accounting for the 2017 business combinations is preliminary except for the Corbett acquisition. We expect to record adjustments as we accumulate information needed to estimate the fair value of assets acquired and liabilities assumed, including working capital balances, estimated fair value of identifiable intangible assets, property, plant and equipment, adjustments related to determination of the conclusion of tax attributes as of the acquisition date, total consideration and goodwill. The following table presents the total consideration for the 2017 acquisitions and the preliminary amounts related to the assets acquired and liabilities assumed based on the estimated fair values as of the respective acquisition dates (in thousands): Polaris 2017 Acquisitions (Excluding Polaris) Cash $ 20,678 $ — Accounts receivable (1) 4,661 1,110 Inventory 6,022 695 Other current assets 1,522 48 Property, plant and equipment 198,703 63,145 Other long-term assets 896 — Definite-lived intangible assets — 8,378 Total assets acquired 232,482 73,376 Current liabilities (2) 26,465 1,057 Other long-term liabilities 2,999 62 Total liabilities assumed 29,464 1,119 Non-controlling interest 21,442 — Goodwill 61,192 12,842 Total consideration (fair value) (3) $ 242,768 $ 85,099 (1) Except for Polaris, the aggregate fair value of the 2017 acquisitions' acquired accounts receivable approximated the aggregate gross contractual amount. The fair value of Polaris's acquired accounts receivable was $4.7 million , which represented an aggregate gross contractual amount of $5.0 million , less estimated amounts not expected to be collected. (2) Current liabilities for Polaris included $14.2 million payable to the Company, which was eliminated in consolidation. (3) Included $29.5 million of deferred and contingent consideration for acquisitions other than Polaris. Acquired Intangibles and Goodwill A summary of the intangible assets acquired in 2018 and 2017 and their estimated useful lives is as follows (in thousands): Weighted Average Amortization Period (In Years) Fair Value At Acquisition Date Customer relationships 7.20 $ 19,325 Non-compete agreements 5.00 1,794 Favorable Contract 3.67 384 Total $ 21,503 As of March 31, 2018 , the estimated future aggregate amortization expense of definite-lived intangible assets from the 2018 and 2017 acquisitions was as follows (in thousands): Year Ending December 31, 2018 (remainder of the year) $ 2,499 2019 3,332 2020 3,315 2021 3,194 2022 3,165 Thereafter 5,387 Total $ 20,892 During the three months ended March 31, 2018 , we recorded $0.3 million of amortization expense related to these intangible assets. During the three months ended March 31, 2017 , there was no amortization expense related to these intangible assets, as they were all subsequently acquired. The goodwill ascribed to our 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. The goodwill relates to our ready-mixed concrete and aggregate products segments. See Note 6 for the allocation of goodwill to our segments. We expect the goodwill to be deductible for tax purposes. See Note 9 for additional information regarding income taxes. Actual Impact of Acquisitions During the three months ended March 31, 2018 , we recorded approximately $30.3 million of revenue and $0.1 million of operating loss in our condensed consolidated statements of operations related to the 2017 and 2018 acquisitions following their respective dates of acquisition. During the three months ended March 31, 2017 , there were no acquisitions. Unaudited Pro Forma Impact of Acquisitions The information presented below reflects the unaudited pro forma combined financial results for the acquisitions completed during 2018 and 2017 , excluding the individually immaterial acquisitions in 2018 and 2017 as described above, as historical financial results for these operations were not material and were impractical to obtain from the former owners. All other acquisitions have been included and represent our estimate of the results of operations for the three months ended March 31, 2018 and 2017 , as if the 2018 acquisitions had been completed on January 1, 2017 and the 2017 acquisitions had been completed on January 1, 2016 (in thousands, except per share information): Three Months Ended 2018 2017 Revenue from continuing operations $ 342,525 $ 342,017 Net income attributable to U.S. Concrete $ (2,731 ) $ 7,620 Net income per share attributable to U.S. Concrete - basic $ (0.17 ) $ 0.49 Net income per share attributable to U.S. Concrete - diluted $ (0.17 ) $ 0.46 The above pro forma results are unaudited and were prepared based on the historical U.S. GAAP results of the Company and the historical results of the 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 2018 acquisitions occurred on January 1, 2017, and the 2017 acquisitions occurred on January 1, 2016. The unaudited pro forma net income attributable to U.S. Concrete and per share amounts above reflect the following adjustments (in thousands): Three Months Ended 2018 2017 Increase in intangible amortization expense $ (479 ) $ (766 ) Increase in depreciation expense — (1,175 ) Exclusion of buyer transaction costs 499 231 Exclusion of seller transaction costs — 3,224 Increase in expenses related to conversions from IFRS (1) to U.S. GAAP — (69 ) Decrease in income tax expense 426 359 Increase in non-controlling loss — 137 (1) IFRS is defined as International Financial Reporting Standards as issued by the International Accounting Standards Board. 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.

These unfavorable lease intangibles have a weighted average remaining life of 4.77 years as of March 31, 2018 . We recorded $5.4 million and $5.2 million of amortization expense on our definite-lived intangible assets and unfavorable lease intangibles for the three months ended March 31, 2018 and 2017 , respectively. This amortization expense is included in the accompanying condensed consolidated statements of operations.

Senior Secured Credit Facility As of March 31, 2018 , we had $17.5 million of undrawn standby letters of credit under our senior secured credit facility ("Revolving Facility"). The weighted average interest rate for the facility was 2.95% as of March 31, 2018 . Our actual maximum credit availability under the Revolving Facility varies from time to time and is determined by calculating the value of our eligible accounts receivable, inventory, mixer trucks and machinery, minus reserves imposed by the lenders and certain other adjustments. Our availability under the Revolving Facility at March 31, 2018 was $137.7 million . We are required, upon the occurrence of certain events, to maintain a fixed charge coverage ratio of at least 1.0 to 1.0 for each period of 12 calendar months. As of March 31, 2018 , we were in compliance with all covenants under the loan agreement that governs the Revolving Facility.

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	3 Months Ended

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 independent sources. 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 as of March 31, 2018 and December 31, 2017 (in thousands): March 31, 2018 Total Level 1 Level 2 Level 3 Contingent consideration, including current portion (1) $ 60,997 $ — $ — $ 60,997 $ 60,997 $ — $ — $ 60,997 December 31, 2017 Total Level 1 Level 2 Level 3 Contingent consideration, including current portion (1) $ 61,817 $ — $ — $ 61,817 $ 61,817 $ — $ — $ 61,817 (1) The current portion of contingent consideration is included in accrued liabilities in our condensed consolidated balance sheets. The long-term portion of contingent consideration is included in other long-term obligations and deferred credits in our condensed consolidated balance sheets. The following tables present the valuation inputs for the fair value estimates of our contingent consideration associated with the 2015 acquisition of Ferrara Bros. Building Materials Corp. ("Ferrara Bros"), 2017 acquisition of Corbett, 2015 acquisition of Right Away Redy Mix, Inc. ("Right Away"), 2018 acquisition of On Time, 2015 acquisition of DuBrook Concrete, Inc. ("DuBrook") and two of the individually immaterial 2017 acquisitions ("Other"). As of March 31, 2018 Valuation Inputs Ferrara Bros Corbett Right Away On Time DuBrook Other Fair value (in millions) $ 33.1 $ 21.0 $ 2.1 $ 0.9 $ 0.5 $ 3.4 Discount rate 11.75 % 5.00 % 9.75 % 3.70 % 15.75 % 3.70 % Payment cap (in millions) $ 35.0 $ 23.0 $ 2.2 $ 1.0 $ 0.5 $ 3.9 Expected payment period remaining (in years) 4 5 2 1 1 5 Management projections of the payout criteria EBITDA Permitted reserves Volumes Volumes Volumes Certain other criteria As of December 31, 2017 Valuation Inputs Ferrara Bros Corbett Right Away DuBrook Other Fair value (in millions) $ 33.0 $ 20.9 $ 4.1 $ 0.5 $ 3.3 Discount rate 11.75 % 5.00 % 9.75 % 15.75 % 3.70 % Payment cap (in millions) $ 35.0 $ 23.0 $ 4.3 $ 0.5 $ 3.9 Minimum payment period from the acquisition date (in years) 4 2 4 2 5 Management projections of the payout criteria EBITDA Permitted reserves Volumes Volumes Certain other criteria The following table provides a reconciliation of the changes in Level 3 fair value measurements from December 31, 2017 to March 31, 2018 (in thousands): Contingent Consideration Balance at December 31, 2017 $ 61,817 Acquisitions (1) 893 Increases in contingent consideration valuation 368 Payments of contingent consideration (2,081 ) Balance at March 31, 2018 $ 60,997 (1) Represents the fair value of the contingent consideration associated with the On Time acquisition as of the acquisition date. The liabilities for the Right Away earn-out and the Ferrara Bros contingent consideration were valued using Monte Carlo simulations, which incorporated probability-weighted assumptions related to the achievement of specific milestones mentioned above. The liabilities for the Corbett and the On Time contingent consideration were valued using the income approach, which incorporated probability-weighted assumptions related to the achievement of specific milestones mentioned above. The liability for the DuBrook earn-out was valued using a discounted cash flow technique. Inputs into the models were based upon observable market data where possible. Where observable market data did not exist, we modeled inputs based upon similar observable inputs. Our other financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, and long-term debt. We consider the carrying values of cash and cash equivalents, accounts receivable, and accounts payable to be representative of their respective fair values because of their short-term maturities or expected settlement dates. The fair value of our 6.375% senior unsecured notes due 2024 ("2024 Notes"), which was estimated based on quoted market prices (i.e., Level 2 inputs), was $623.2 million as of March 31, 2018 . The carrying value of the outstanding amounts under our Revolving Facility approximates fair value due to the floating interest rate.

INCOME TAXES

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES We recorded income tax expense allocated to continuing operations of $1.7 million and $6.7 million for the three months ended March 31, 2018 and 2017 , respectively. For the three months ended March 31, 2018 , our effective tax rate differed from the federal statutory rate primarily due to the fact that our Canadian operations had a net pre-tax loss for which no income tax benefit is recorded because of a related full valuation allowance. Our other entities had net pre-tax income and recorded corresponding net income tax expense, which included cumulative adjustments related to deferred income taxes in the amount of $1.3 million . For the three months ended March 31, 2017 , our effective tax rate was higher than the federal statutory tax rate primarily due to adjustments related to certain state net operating loss carryforwards that will not be utilized prior to expiration and other cumulative adjustments to deferred income taxes, which resulted in additional income tax expense. In addition, both periods were impacted by certain state income taxes that were calculated on a basis other than pre-tax income (loss). In accordance with U.S. GAAP, we reduce the value of deferred tax assets 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 generating 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, 2018 and December 31, 2017 for other deferred tax assets because of uncertainty regarding their ultimate realization. Our total net deferred tax liability was approximately $3.1 million as of March 31, 2018 and $4.8 million as of December 31, 2017 . We record changes in our unrecognized tax benefits based on anticipated federal and state tax filing positions on a quarterly basis. For the three months ended March 31, 2018 and 2017 , we recorded unrecognized tax benefits of $0.1 million and $0.6 million , respectively. On December 22, 2017, the President signed into law “H.R.1” for U.S. tax reform legislation (the “Tax Act”). Among other items, the Tax Act lowered the corporate federal statutory tax rate from 35% to 21%. We estimate a decrease to our 2018 tax expense primarily due to the lower blended effective U.S. federal tax rate. The Tax Act also contains certain provisions that could impact our taxable income beginning in tax year 2018, including, but not limited to (1) a Base Erosion Anti-abuse Tax ("BEAT"), which is a new minimum tax; (2) general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (3) a mechanism to tax currently global intangible low taxed income ("GILTI"), which allows for the possibility of utilizing foreign tax credits and a deduction equal to 50% to offset the income tax liability (subject to some limitations); (4) allowing us to elect treatment of the GILTI as a period cost or in deferred taxes; (5) a limit on the amount of deductible interest expense; (6) the repeal of the domestic production activity deduction; (7) limitations on the deductibility of certain executive compensation; and (8) limitations on the utilization of foreign tax credits to reduce the U.S. income tax liability. Shortly after the Tax Act was enacted, the Securities and Exchange Commission ("SEC") staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the Tax Act’s impact. This guidance provides a measurement period, which in no case should extend beyond one year from the Tax Act enactment date. For the period ended December 31, 2017, we recorded provisional amounts related to the remeasurement of our deferred income tax assets and liabilities based on the income tax rates that are expected to be in effect at the time the tax deduction or taxable item will be reported in our income tax returns, as well as assessed our ability to realize deferred income tax assets in the future under the new rules of the Tax Act. Additionally, we assessed the impacts of the new provisions associated with the deductibility of executive compensation under Internal Revenue Code Section 162(m), and the associated “grandfathering” rules within the Tax Act to provide taxpayers transition relief when applying the change in law. At March 31, 2018, we have not completed our accounting for the income tax effects of the Tax Act; however, in certain cases, we have made a reasonable estimate of the effects on our existing deferred income tax balances. We will monitor future guidance set forth by the U.S. Department of Treasury with regard to the new provisions under the Tax Act, and true up provisional amounts as appropriate within the one-year measurement period required under SAB 118.

Earnings Per Share [Abstract]
NET EARNINGS (LOSS) PER SHARE	NET EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share is computed by dividing net earnings (loss) attributable to U.S. Concrete by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is computed by dividing net earnings (loss) attributable to U.S. Concrete by the weighted average number of common shares outstanding during the period after giving effect to all potentially dilutive securities outstanding during the period. The following is a reconciliation of the components of the basic and diluted earnings (loss) per share calculations for the three months ended March 31, 2018 and 2017 (in thousands): Three Months Ended 2018 (1) 2017 Numerator for basic and diluted earnings per share: Income (loss) from continuing operations attributable to U.S. Concrete $ (3,858 ) $ 7,002 Loss from discontinued operations, net of taxes — (122 ) Net income (loss) attributable to U.S. Concrete $ (3,858 ) $ 6,880 Denominator for diluted earnings per share: Basic weighted average common shares outstanding 16,423 15,498 Restricted stock and restricted stock units — 117 Warrants — 851 Stock options — 17 Diluted weighted average common shares outstanding 16,423 16,483 (1) We reported a loss from continuing operations attributable to U.S. Concrete for the three months ended March 31, 2018; therefore, the share count used in the basic and diluted earnings per share calculation is the same.

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 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 contributing employers in the plans has an effect on each of the 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 31, 2018 , 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. 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 product defect claims related to ready-mixed concrete we have delivered prior to March 31, 2018 . 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, 2018 . 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. Royalty Assessment In 2014, Eagle Rock Materials Ltd. (“ERM”), a Polaris subsidiary, was notified by the British Columbia Ministry of Forests, Lands and Natural Resource Operations that royalties were due for 2012 and 2013, based on the tenure date, in respect of Polaris’s quarrying lease for the Eagle Rock Quarry project. In 2016, ERM was notified that further royalties were due for 2014, 2015 and 2016 (up to October) based on the tenure date, and in 2017, ERM was notified of interest charges of $0.4 million . The total royalties and interest claimed to date are approximately $2.2 million , which the Company, through its Polaris subsidiary, is disputing. Polaris’s position is that royalties are only payable based on actual production, in accordance with a written undertaking from the responsible government agency prior to commencement of the lease, and as the project has not been developed, no royalties are currently due. Accordingly, the Company has currently not recorded a provision for the royalty assessment. Insurance Programs We maintain third-party insurance coverage against certain workers' compensation, automobile and general liability 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, 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 recorded in accrued liabilities and other long-term obligations in our condensed consolidated balance sheet for estimated losses was $19.7 million as of March 31, 2018 and $19.2 million as of December 31, 2017 . Performance Bonds In the normal course of business, we are contingently liable for performance under $34.5 million in performance bonds that various contractors, states and municipalities have required as of March 31, 2018 . The bonds principally relate to construction contracts, reclamation obligations, 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 as of March 31, 2018 . Employment Agreements We have employment agreements with executive officers and certain key members of management under which severance payments would become payable in the event of specified terminations without cause or after a change of control.

SEGMENT INFORMATION

SEGMENT INFORMATION	3 Months Ended

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 markets: Texas, Northern California, New York, New Jersey, Pennsylvania, Washington, D.C., Oklahoma and the U.S. Virgin Islands. Our aggregate products segment includes crushed stone, sand and gravel products and serves the markets in which our ready-mixed concrete segment operates as well as the West Coast and Hawaii. Other products not associated with a reportable segment include our aggregates distribution operations, building materials stores, hauling operations, lime slurry, ARIDUS ® Rapid Drying Concrete technology, brokered product sales, recycled aggregates operation and an industrial waterfront marine terminal and sales yard. The financial results of the acquisitions have been included in their respective reportable segment or in other products, as applicable, 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 is 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 income (loss) from continuing operations excluding the impact of income tax expense (benefit), depreciation, depletion and amortization, net interest expense, loss on extinguishment of debt, derivative income (loss), the non-cash change in value of contingent consideration, impairment of goodwill and other assets, hurricane-related losses, quarry dredge costs for a specific event, purchase accounting adjustments for inventory and foreign currency losses resulting from the Polaris acquisition. Other impacts excluded from our Adjusted EBITDA are non-cash stock compensation expense, acquisition-related costs and officer transition expenses. Many of the impacts excluded to derive Adjusted EBITDA are similar to those excluded for use in calculating our compliance with debt covenants. 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 (1) internally measure our operating performance and (2) 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 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, and may not be comparable to similarly titled measures used in the agreements governing our debt. We generally account for inter-segment sales at market prices.

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," the "Company," or "U.S. Concrete") and have been prepared 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, 2017 (the " 2017 Form 10-K"). In the opinion of our management, all material adjustments necessary to state fairly the information in our unaudited condensed consolidated financial statements have been included. All adjustments are of a normal or recurring nature. All amounts are presented in United States dollars, unless otherwise noted. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.
Use of Estimates	The preparation of financial statements and accompanying notes in conformity with 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 revenue 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, business combinations, goodwill, intangibles, valuation of contingent consideration, accruals for self-insurance programs, income taxes, the valuation of inventory and the valuation and useful lives of property, plant and equipment.
Recent Accounting Pronouncements	Standards/Updates Adopted This Quarter Revenue Recognition. In May 2014, the FASB issued guidance that outlines a single comprehensive model for accounting for revenue arising from contracts with customers, which supersedes most of the existing revenue recognition guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and also requires certain additional disclosures. We adopted this guidance and related amendments as of January 1, 2018, applying the modified retrospective transition approach to all contracts. Adoption of the new guidance did not result in changes in the amount of revenue recognized or the timing of when such revenue is recognized. Clarification of the Definition of a Business in Business Combinations. In January 2017, the FASB issued an update under business combinations in an effort to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or as business combinations. The amendments in this update provide a screen to determine when a set of assets is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. The adoption of this standard did not have a material impact on our financial condition and results of operations. Classification of Certain Cash Receipts and Cash Payments. In August 2016, the FASB issued guidance to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. Adoption of this standard did not result in any material changes to our statements of cash flows. Standards/Updates Not Yet Adopted Lease Accounting. In February 2016, the FASB issued an amendment related to leases intended to increase transparency and comparability among organizations by reorganizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, lessees will be required to recognize a right-of-use asset and a lease liability, measured on a discounted basis, at the commencement date for all leases with terms greater than twelve months. Additionally, this guidance will require disclosures to help investors and other financial statement users to better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. We expect to adopt the guidance using a modified retrospective transition approach. This guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual periods. We are currently evaluating the potential impact on our financial position and results of operations upon adoption of this guidance. This guidance will result in our existing operating leases, for certain real estate and equipment, to be recognized on our balance sheet. We will further analyze our lease arrangements as we complete our assessment and implementation of this new guidance. The evaluation process will include reviewing all forms of leases, performing a completeness assessment over the lease population, analyzing the practical expedients and assessing the need to make any changes to our lease accounting technology system in order to determine the best implementation strategy.
