U.S. Concrete Wins GreenSite Award for California Academy of Sciences

HOUSTON, Nov. 12 /PRNewswire-FirstCall/ -- U.S. Concrete, Inc., (Nasdaq: RMIX)
announced today that it has won the 2009 GreenSite Award in the Institutional
category for outstanding sustainability practices in concrete construction, an
award bestowed by The Concrete Producer, a Hanley Wood Business Media Company.
The award was for the production of environmentally-friendly concrete in the
construction of The California Academy of Sciences building in San Francisco,
California.

Environmentally-friendly technologies and sustainability are becoming crucial
building practices in the competitive world of concrete construction. To
recognize innovative contributions to green building, Concrete Construction
Magazine and The Concrete Producer Magazine created a new award: GreenSite
Project of the Year.

The California Academy of Sciences is one of the largest and most renowned
institutions of natural history, science and culture in the world.
Sustainability and conservation have long been a part of the Academy's
history, and this innovative new building serves as a tangible example of
environmentally-superior construction at the forefront of sustainability
design, receiving Platinum certification under the U.S. Green Building
Council's LEED program. Environmentally-friendly concrete formed an integral
part of the building's construction and on-going sustainable system. San
Francisco-based Central Concrete Supply Co., Inc., a subsidiary of U.S.
Concrete, Inc., provided approximately 35,000 cubic yards of concrete,
utilizing its environmentally-friendly technology (EF Technology(TM)) concrete
mixes.

All of the GreenSite Award winners will be featured in the October/November
issues of The Concrete Producer and Concrete Construction Magazines. The
California Academy of Sciences project slideshow will also be showcased on
their Web sites, www.theconcreteproducer.com and www.concreteconstruction.net,
and GreenSite Award projects will also be displayed at World of Concrete
Tradeshow, February 2-5, 2010.

EF Technology mixes utilize supplementary cementitious materials, such as fly
ash and slag, which are reclaimed by-products from iron mills and coal-fired
power plants which may have ultimately ended up in landfills. U.S. Concrete
estimates that their concrete mix designs prevented one million pounds of
greenhouse gas emissions (CO2) from entering the environment over the past
three years.
