Re:	U.S. Concrete, Inc. Registration Statement on Form S-4 (File No. 333-186493)

Ladies and Gentlemen:

We have acted as counsel to U.S. Concrete, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing by the Company with the Securities and Exchange Commission of a Registration Statement on Form S-4, as amended (File No. 333‑186493)(the “Registration Statement”), under the Securities Act of 1933, as amended (the “Act”). The Registration Statement relates to (i) up to $69,300,000 aggregate principal amount of 9.5% Senior Secured Notes Due 2015 (the “New Securities”) of the Company to be issued pursuant to an Indenture (the “New Indenture”) to be entered into by the Company, the subsidiaries of the Company set forth in Schedule I (each a “Guarantor” and collectively, the “Guarantors”) and U.S. Bank National Association, as trustee (the “Trustee”), pursuant to the exchange offer (the “Exchange Offer”) described in the Registration Statement and (ii) the guarantees by the Guarantors of the New Securities pursuant to the New Indenture (the “New Guarantees”). The Company has previously issued $55,000,000 aggregate principal amount of 9.5% Convertible Secured Notes due 2015 under the Indenture, dated August 31, 2010, by and among the Company, the Guarantors, and the Trustee, as trustee, as amended by the First Supplemental Indenture, dated as of October 30, 2012, by and among Bode Gravel Co. and Bode Concrete LLC, as new guarantors, and the Trustee, as trustee (the Old Convertible Indenture and Old Convertible Securities, as so amended, the “Old Convertible Indenture” and the “Old Convertible Securities”). If any of the Old Convertible Securities are not exchanged for New Securities in the Exchange Offer, the remaining Old Convertible Securities and the Old Convertible Indenture will be amended by the Second Supplemental Indenture (the “Supplemental Indenture”) to be entered into by and among the Company, the Guarantors and the Trustee, as trustee (the Old Convertible Indenture and Old Convertible Securities, as so amended, the “Amended Convertible Indenture” and the “Amended Convertible Securities”). The Registration Statement also relates to (i) the Amended Convertible Securities, if any, and (ii) the guarantees by the Guarantors of the Amended Convertible Securities pursuant to the Amended Convertible Indenture (the “Amended Convertible Guarantees”). We refer to the Amended Convertible Indenture and the New Indenture collectively as the “Indentures,” the Amended Convertible Securities and the New Securities collectively as the “Securities,” and the Indentures, the Securities and the Supplemental Indenture collectively as the “Opinion Documents.” This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act.

2.	When the Supplemental Indenture has been duly executed and delivered by the Company, the Guarantors and the Trustee, (i) the Amended Convertible Securities will be valid and binding obligations of the Company and (ii) the Amended Convertible Guarantees will be valid and binding obligations of the Guarantors.
