If you wish to exchange issued and outstanding 8.500% Senior Secured Notes due 2018 (the “Initial Notes”) for an equal principal amount of 8.500% Senior Secured Notes due 2018 (the “Exchange Notes”) that have been registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to the exchange offer, you must validly tender (and not validly withdraw) the Initial Notes to U.S. Bank National Association (the “Exchange Agent”) prior to the Expiration Date.

The undersigned hereby acknowledges receipt and review of the Prospectus, dated June [    ], 2014 (the “Prospectus”), of U.S. Concrete, Inc. (the “Issuer”), and this Letter of Transmittal (the “Letter of Transmittal”), which together describe the Issuer’s offer (the “Exchange Offer”) to exchange their issued and outstanding Initial Notes for an equal principal amount of Exchange Notes. Capitalized terms used but not defined herein have the respective meaning given to them in the Prospectus.

The Issuer reserves the right, at any time or from time to time, to extend the Exchange Offer at its discretion. The Issuer shall notify the Exchange Agent and each registered holder of the Initial Notes of any extension by oral or written notice prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

This Letter of Transmittal is to be used by holders of the Initial Notes. Tender of Initial Notes is to be made according to the Automated Tender Offer Program (“ATOP”) of The Depository Trust Company (“DTC”) pursuant to the procedures set forth in the Prospectus under the caption “The Exchange Offer—Procedures for Tendering Initial Notes.” DTC participants that are accepting the Exchange Offer must transmit their acceptance to DTC, which will verify the acceptance and execute a book-entry delivery to the Exchange Agent’s DTC account. DTC will then send a computer-generated message known as an “agent’s message” to the Exchange Agent for its acceptance. For you to validly tender your Initial Notes in the Exchange Offer, the Exchange Agent must receive, prior to the Expiration Date, an agent’s message under the ATOP procedures that confirms that:

• DTC has received your instructions to tender your Initial Notes; and

• you agree to be bound by the terms of this Letter of Transmittal.
