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, 2018 (the " 2018 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. Certain computations may be impacted by the effect of rounding in this report. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. Certain reclassifications have been made to prior year amounts to conform with the current year presentation. 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, income taxes, the valuation of inventory and the valuation and useful lives of property, plant and equipment.

RECENT ACCOUNTING PRONOUNCEMENT

Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS AND SIGNIFICANT ACCOUNTING POLICIES	RECENT ACCOUNTING PRONOUNCEMENTS AND SIGNIFICANT ACCOUNTING POLICIES Recently Adopted - Lease Accounting. In February 2016, the Financial Accounting Standards Board ("FASB") issued a new lease accounting standard intended to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, lessees are required to recognize a right-of-use asset and a lease liability, measured on a discounted basis, at the commencement date for all leases, excluding mineral interest leases, with terms greater than twelve months. Additionally, this guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. We adopted the guidance as of January 1, 2019, using the transition approach that permitted application of the new standard at the adoption date instead of the earliest comparative period presented in the financial statements. We implemented processes and information technology tools to assist in our ongoing lease data collection and analysis and in updating internal controls that were impacted by the new guidance. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification. We also elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements. We elected to exclude leases with an initial term of 12 months or less from the balance sheet. We made an accounting policy election to combine lease and non-lease components when calculating the lease liability under the new standard. Non-lease components, which may include taxes, maintenance, insurance and certain other expenses applicable to the leased property, are primarily considered variable costs. We did not elect the hindsight practical expedient to determine the lease term for existing leases. As a result of adopting the new standard, we recorded additional lease assets and lease liabilities of approximately $76.9 million and $79.2 million , respectively, on the balance sheet as of January 1, 2019. The additional lease assets equal the lease liabilities, excluding the impact of deferred rent, which was previously recorded in accrued liabilities. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. Not Yet Adopted - Credit Losses. In June 2016, the FASB issued an update on the measurement of credit losses on financial instruments, which requires entities to use a forward-looking approach based on expected losses rather than the current model of incurred losses to estimate credit losses on certain types of financial instruments, including trade accounts receivable. Application of the new model may result in the earlier recognition of allowances for losses. The guidance becomes effective for us on January 1, 2020, with early adoption permitted. We are in the process of assessing the impact of this new standard on our consolidated financial statements. For our other significant accounting policies, see Note 1 to the consolidated financial statements in our 2018 10-K.

Leases [Abstract]
LEASES	LEASES We are the lessee in a lease contract when we obtain the right to control the asset. We lease certain land, office space, equipment and vehicles. Most leases include one or more options to renew, with renewal terms that can extend the lease term from one to 20 years or more. The exercise of lease renewal options is primarily at our discretion. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Certain of our lease agreements include rental payments based on a percentage of volume sold over contractual levels and others include rental payments adjusted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Where observable, we use the implicit interest rate in determining the present value of future payments. Where the implicit interest rate is not observable, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. We give consideration to our outstanding debt as well as publicly available data for instruments with similar characteristics when calculating our incremental borrowing rates.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS We completed five acquisitions during 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, aggregate products and other non-reportable operations in West Texas. The aggregate fair value consideration for these acquisitions, which were all accounted for as business combinations, was $70.8 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, and Texas Sand & Gravel Co., Inc. (collectively " Golden Spread ") located in Amarillo, Texas on March 2, 2018 ; • Leon River Aggregate Materials, LLC ("Leon River") located in Proctor, Texas on August 29, 2018 ; and • Two individually immaterial ready-mixed concrete operations in our Atlantic Region and West Texas Region on March 5, 2018 and September 14, 2018 , respectively. The aggregate fair value consideration for these five acquisitions included $69.9 million in cash and fair value contingent consideration of $1.1 million and was net of a working capital receivable of $0.2 million . We funded the cash portion through a combination of cash on hand and borrowings under our Revolving Facility (as defined in Note 7 ). The combined assets acquired through these acquisitions included 149 mixer trucks, 20 concrete plant facilities and two aggregate facilities. To effect these transactions, during the three and nine months ended September 30, 2018 , we incurred $0.3 million and $0.9 million of transaction costs, respectively, which were included in selling and general administrative expenses in our condensed consolidated statements of operations. See Note 6 for a description of our measurement period adjustments. The following table presents the total consideration for the 2018 acquisitions and the amounts related to the assets acquired and liabilities assumed based on the estimated fair values as of their respective acquisition dates: ($ in millions) 2018 Acquisitions Inventory $ 1.1 Other current assets 0.1 Property, plant and equipment 37.4 Definite-lived intangible assets 19.8 Total assets acquired 58.4 Current liabilities 0.1 Other long-term liabilities 1.1 Total liabilities assumed 1.2 Goodwill 13.6 Total consideration (fair value) (1) $ 70.8 (1) Included $1.1 million of contingent consideration. Acquired Intangible Assets and Goodwill A summary of the intangible assets acquired in 2018 and their estimated useful lives is as follows: ($ in millions) Weighted Average Amortization Period (In Years) Fair Value At Acquisition Date Customer relationships 5.5 $ 18.5 Non-compete agreements 5.0 1.3 Total $ 19.8 As of September 30, 2019 , the estimated future aggregate amortization expense of definite-lived intangible assets from the 2018 acquisitions was as follows (in millions): 2019 (remainder of the year) $ 0.9 2020 3.6 2021 2.8 2022 2.6 2023 1.6 Thereafter 1.8 Total $ 13.3 During the three and nine months ended September 30, 2019 , we recorded $1.1 million and $3.6 million of amortization expense related to these intangible assets, respectively. For the three months ended September 30, 2019 , there were no measurement period adjustments related to these intangible assets. For the nine months ended September 30, 2019 , there were measurement period adjustments of $0.5 million related to these intangible assets. During the three and nine months ended September 30, 2018 , we recorded $1.1 million and $1.9 million of amortization expense related to these intangible assets, respectively. For the three and nine months ended September 30, 2018 , there were measurement period adjustments of $0.2 million and $0.3 million related to these intangible assets, respectively. The goodwill ascribed to the 2018 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 other non-reportable segments in the amounts of $12.8 million and $0.8 million , respectively. We generally expect all $13.6 million of goodwill from the 2018 acquisitions to be deductible for tax purposes. See Note 10 for additional information regarding income taxes. Impact of Acquisitions During the three months ended September 30, 2018 , we recorded $12.0 million of revenue and $1.4 million of operating loss in our condensed consolidated statements of operations related to the 2018 acquisitions following their respective dates of acquisition. During the nine months ended September 30, 2018 , we recorded approximately $33.6 million of revenue and $2.3 million of operating income in our condensed consolidated statements of operations related to the 2018 acquisitions following their respective dates of acquisition. The information presented below reflects the unaudited pro forma combined financial results for the 2018 acquisitions, excluding the individually immaterial acquisitions 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 2018 results of operations as if the 2018 acquisitions had been completed on January 1, 2017. The impact to the 2019 results of operations if the 2018 acquisitions had been completed on January 1, 2017 was not materially different from our reported results.

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 September 30, 2019 was $236.1 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 September 30, 2019

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	9 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. There were no transfers of assets or liabilities between the fair value measurement levels for the three and nine months ended September 30, 2019 or the year ended December 31, 2018 . We estimate the fair value of acquisition-related contingent consideration arrangements using a Monte Carlo simulation model, an income approach or a discounted cash flow technique, as appropriate. The fair value of the contingent consideration arrangements is sensitive to changes in the forecasts of earnings and/or the relevant operating metrics and changes in discount rates. The fair value of the contingent consideration is reassessed quarterly based on assumptions used in our latest projections and input provided by practice leaders and management. Any change in the fair value estimate is recorded in our consolidated statement of operations for that period. The current portion of contingent consideration is included in accrued liabilities while the long-term portion is included in other long-term obligations and deferred credits, both of which are in our condensed consolidated balance sheets. The use of different estimates and assumptions could increase or decrease the estimated fair value of our contingent consideration liability, which would result in different impacts to our consolidated balance sheets and consolidated statements of operations. These fair value measurements are based on significant inputs not observable in the market, and thus represent Level 3 inputs. Our recurring Level 3 fair value liability, contingent consideration, including the current portion, was $26.0 million as of September 30, 2019 and $60.7 million as of December 31, 2018 . The following tables present the inputs for the models used to value our acquisition-related contingent consideration: September 30, 2019 Valuation Inputs Monte Carlo Simulation Income Approach Fair value (in millions) $ 23.6 $ 2.4 Discount rate 11.00 % 3.70% - 10.75% Payment cap (in millions) $ 26.3 $ 2.5 Expected payment period remaining (in years) 2.6 0 - 4 Management projections of the payout criteria EBITDA Volumes December 31, 2018 Valuation Inputs Monte Carlo Simulation Income Approach Discounted Cash Flow Technique Fair value (in millions) $ 33.2 $ 26.5 $ 1.0 Discount rate 10.75% - 12.25% 3.70% - 5.00% 6.03% - 15.75% Payment cap (in millions) $ 37.3 $ 27.3 $ 1.1 Expected payment period remaining (in years) 1-3 1 1-4 Management projections of the payout criteria EBITDA/Volumes Permitted reserves/Volumes Volumes The following table provides a reconciliation of the changes in Level 3 fair value measurements from December 31, 2018 to September 30, 2019 : ($ in millions) Contingent Consideration Balance at December 31, 2018 $ 60.7 Change in valuation 1.6 Payments of contingent consideration (36.3 ) Balance at September 30, 2019 $ 26.0 Other Financial Instruments 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 $615.7 million as of September 30, 2019 . The carrying value of the outstanding amounts under our Revolving Facility approximates fair value due to the floating interest rate. Other Assets and Liabilities Measured on a Non-Recurring Basis In connection with our acquisitions described in Note 4 , the assets acquired and liabilities assumed were recorded at their fair value on a non-recurring basis as of their respective acquisition dates. We generally use a third-party valuation firm to assist us with developing our estimates of fair value. The fair value of property, plant and equipment was based primarily on a market valuation approach. Additionally, we may use a cost valuation approach to value long-lived assets when a market valuation approach is unavailable. In determining the fair value of intangible assets, we utilized the cost approach (primarily through the cost-to-recreate method), the market approach and the income approach. The income approach may incorporate the use of a discounted cash flow method. In applying the discounted cash flow method, the estimated future cash flows and residual values for each intangible asset are discounted to a present value using a discount rate based on an estimated weighted average cost of capital for the building materials industry. These cash flow projections were based on management’s estimates of economic and market conditions including revenue growth rates, operating margins, capital expenditures and working capital requirements. The valuations were prepared using Level 3 inputs.

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION	9 Months Ended

Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION Effective February 13, 2019, we amended the U.S. Concrete, Inc. Long Term Incentive Plan (the "Amendment") to reserve an additional 0.9 million shares of common stock for future issuance as equity-based awards to management and employees. On March 1, 2019, the Compensation Committee of the Board of Directors approved grants of 0.3 million restricted stock units (the "2019 RSU Grant"), conditioned upon obtaining stockholder approval of the Amendment. The Amendment was approved by the Company's stockholders at the Company's annual meeting in May 2019, and the stockholder approval condition related to the 2019 RSU Grant was satisfied. We recognized stock-based compensation expense of $5.3 million and $16.4 million during the three and nine months ended September 30, 2019 , respectively, and $2.9 million and $8.1 million during the three and nine months ended September 30, 2018, respectively. Stock-based compensation expense is reflected in selling, general and administrative expenses in our consolidated statements of operations. The 2019 RSU Grant consisted of a 60% time-vested component that vests annually over a three -year period and a 40% stock performance hurdle component. The stock performance hurdle component triggers vesting upon our stock price reaching certain thresholds and may vest up to 200% of the target number of performance stock units granted. The fair value of the 2019 RSU Grant subject only to time-based vesting restrictions was determined based upon the closing price of our common stock on the effective date of the grant. The fair value of the 2019 RSU Grant subject to market performance hurdles was determined utilizing a Monte Carlo financial valuation model. Compensation expense determined utilizing the Monte Carlo simulation is recognized regardless of whether the common stock reaches the defined thresholds, provided that each grantee remains an employee at the end of the expected term. The assumptions used to estimate the fair value of performance-based restricted stock units granted in 2019 were as follows: Expected term (years) 0 to 0.5 Expected volatility 41.1% Risk-free interest rate 2.1% Vesting price (1) $45.90 - $58.60 Grant date fair value per share $39.60 - $48.75 (1) The vesting price is the average of the daily volume-weighted average share price of U.S. Concrete's common stock over any period of 20 consecutive trading days within the three -year period beginning on the date of grant. These hurdles were established on March 1, 2019.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES We recorded income tax expense of $8.3 million for both the three and nine months ended September 30, 2019. For both periods ended September 30, 2019, our effective tax rate was negatively impacted by (i) losses generated by certain of our Canadian subsidiaries for which no income tax benefit was recognized due to a related full valuation allowance, (ii) our estimated annual interest expense limitation in accordance with the Tax Cuts and Jobs Act (the "Tax Act") and related proposed regulations for which a full valuation allowance is anticipated, (iii) our estimated global intangible low-taxed income ("GILTI") inclusion for U.S. tax purposes, (iv) anticipated Section 162(m) limitations on executive compensation and (v) net unfavorable discrete items, including a net tax shortfall recognized for share-based compensation. These unfavorable discrete items were partially offset by certain additional federal and state income tax benefits. For the three and nine months ended September 30, 2018 , we recorded income tax expense of $8.6 million and $14.5 million , respectively. For both periods ended September 30, 2018, our effective tax rate differed from the federal statutory rate primarily due to (i) losses generated by certain of our Canadian subsidiaries for which no income tax benefit was recognized due to a related full valuation allowance, (ii) adjustments related to the tax rate change enacted as part of the Tax Act and (iii) state income taxes. 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 maintained valuation allowances as of September 30, 2019 and December 31, 2018 for certain deferred tax assets because of uncertainty regarding their ultimate realization. Our total net deferred tax liability was $40.0 million as of September 30, 2019 and $38.0 million as of December 31, 2018 , of which $44.9 million and $43.1 million , respectively, were recorded as non-current liabilities. Deferred tax assets for certain state and foreign taxing jurisdictions, which were recorded as non-current assets, were $4.9 million as of September 30, 2019 and $5.1 million as of December 31, 2018 . We record changes in our unrecognized tax benefits based on anticipated federal and state tax filing positions on a quarterly basis. For the three and nine months ended September 30, 2019 , we recognized a net of $0.5 million and $0.1 million , respectively, for previously unrecognized tax benefits. For the three and nine months ended September 30, 2018, we recorded unrecognized tax benefits of $0.1 million and $0.3 million , respectively.

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 other contributing employers in the plans has an effect on each of the other contributing employers, and the development of a rehabilitation plan by the trustees and subsequent submittal to and approval by the Internal Revenue Service is not predictable. Further, the allocation of fund assets and return assumptions by trustees are variable, as are actual investment returns relative to the plan assumptions. As of November 8, 2019 , there were 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 such unasserted product defect claims related to ready-mixed concrete we have delivered prior to September 30, 2019 . We believe that the resolution of any 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 potential liability of these indemnification agreements is minimal. Accordingly, we have not recorded any liabilities for these agreements as of September 30, 2019 . 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. As of November 8, 2019 , there were no material pending claims related to such indemnification. Royalty Assessment In 2014, Eagle Rock Materials Ltd. (“ERM”), a subsidiary of our Canadian aggregates operation, Polaris Materials ("Polaris"), 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. While the Company had previously disputed the claim, ERM settled the claim in May 2019 for CAD $4 million and entered into a repayment agreement that extended the payment terms, as defined. Eminent Domain Matter In 2018, we incurred $0.7 million of expenses to dismantle and move a ready-mixed concrete plant and office to another location, because the District of Columbia exercised its power of eminent domain over the former site. We incurred certain additional expenditures that were capitalized for the new facilities. In June 2019, we received $5.3 million , net of attorney's fees, from the District of Columbia as reimbursement for our costs, which is reported in other income, net, in our consolidated statement of operations. We expect to file an additional request for reimbursement of certain other expenses not included in the initial submission, but have not recognized a receivable for such reimbursement pending approval by a third-party right-of-way agent and the District of Columbia Department of Transportation. Insurance Programs We maintain third-party insurance coverage against certain workers’ compensation, automobile and general liability risks. Under certain components of our insurance program, we share the risk of loss with our insurance underwriters by maintaining high deductibles subject to aggregate annual loss limitations. Generally, our insurance program deductible retentions per occurrence are $1.0 million to $2.0 million for workers’ compensation and general liability and $2.0 million to $10.0 million for automobile, although certain of our operations are self-insured for workers’ compensation. We have deductibles and record an expense for expected losses under the programs. The expected losses are determined using a combination of our historical loss experience and subjective assessments of our future loss exposure. The estimated losses are subject to uncertainty, including changes in claims reporting patterns, claims settlement patterns, judicial decisions, legislation and economic conditions. Although we believe that the estimated losses we have recorded are reasonable, significant differences related to the items noted above could materially affect our insurance obligations and future expense. The amount accrued for self-insurance claims, which was recorded in accrued liabilities and other long-term obligations, was $19.4 million as of September 30, 2019 and $20.4 million as of December 31, 2018 . Performance Bonds In the normal course of business, we and our subsidiaries were contingently liable under $18.4 million in performance bonds that various contractors, states and municipalities have required as of September 30, 2019 . 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.

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, California, New York, New Jersey, Washington, D.C., Pennsylvania, Oklahoma and the U.S. Virgin Islands. Our aggregate products segment produces crushed stone, sand and gravel and serves the markets in which our ready-mixed concrete segment operates as well as the West Coast and Hawaii. Other operations and products not associated with a reportable segment include our aggregates distribution operations, building materials stores, hauling operations, ARIDUS ® Rapid Drying Concrete technology, brokered product sales and recycled aggregates. Other operations and products also previously included lime slurry operations until they were sold on September 5, 2018. 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 our net income (loss), excluding the impact of income tax expense (benefit), depreciation, depletion and amortization, net interest expense and certain other non-cash, non-recurring and/or unusual, non-operating items including, but not limited to: non-cash stock compensation expense, non-cash change in value of contingent consideration, impairment of assets, acquisition-related costs, officer transition expenses, quarry dredge costs for specific event, and hurricane-related losses, net of recoveries. Acquisition-related costs consist of fees and expenses for accountants, lawyers and other professionals incurred during the negotiation and closing of strategic acquisitions and certain acquired entities' management severance costs. Acquisition-related costs do not include fees or expenses associated with post-closing integration of strategic acquisitions. Many of the impacts excluded to derive Adjusted EBITDA are similar to those excluded in calculating our compliance with our 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. Corporate includes executive, administrative, financial, legal, human resources, business development and risk management activities that are not allocated to reportable segments and are excluded from segment Adjusted EBITDA. Eliminations include transactions to account for intercompany activity.

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, 2018 (the " 2018 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. Certain computations may be impacted by the effect of rounding in this report. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. Certain reclassifications have been made to prior year amounts to conform with the current year presentation.
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, income taxes, the valuation of inventory and the valuation and useful lives of property, plant and equipment.
Recent Accounting Pronouncements	Recently Adopted - Lease Accounting. In February 2016, the Financial Accounting Standards Board ("FASB") issued a new lease accounting standard intended to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, lessees are required to recognize a right-of-use asset and a lease liability, measured on a discounted basis, at the commencement date for all leases, excluding mineral interest leases, with terms greater than twelve months. Additionally, this guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. We adopted the guidance as of January 1, 2019, using the transition approach that permitted application of the new standard at the adoption date instead of the earliest comparative period presented in the financial statements. We implemented processes and information technology tools to assist in our ongoing lease data collection and analysis and in updating internal controls that were impacted by the new guidance. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification. We also elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements. We elected to exclude leases with an initial term of 12 months or less from the balance sheet. We made an accounting policy election to combine lease and non-lease components when calculating the lease liability under the new standard. Non-lease components, which may include taxes, maintenance, insurance and certain other expenses applicable to the leased property, are primarily considered variable costs. We did not elect the hindsight practical expedient to determine the lease term for existing leases. As a result of adopting the new standard, we recorded additional lease assets and lease liabilities of approximately $76.9 million and $79.2 million , respectively, on the balance sheet as of January 1, 2019. The additional lease assets equal the lease liabilities, excluding the impact of deferred rent, which was previously recorded in accrued liabilities. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. Not Yet Adopted - Credit Losses. In June 2016, the FASB issued an update on the measurement of credit losses on financial instruments, which requires entities to use a forward-looking approach based on expected losses rather than the current model of incurred losses to estimate credit losses on certain types of financial instruments, including trade accounts receivable. Application of the new model may result in the earlier recognition of allowances for losses. The guidance becomes effective for us on January 1, 2020, with early adoption permitted. We are in the process of assessing the impact of this new standard on our consolidated financial statements.
