In mid-July 2011 the Colorado Department of Transportation began the $32.1 million I-25/Santa Fe Drive Interchange project near downtown Denver. Hamon Contractors was awarded the job and Slaton Bros, working with The Reinforced Earth Company (RECo) and Pacheco CPI, was hired to provide the permanent and temporary retaining walls on the project.
The most common application of Reinforced Earth® is for earth retention of road and highway structures. A Reinforced Earth® retaining wall is a gravity structure consisting of alternating layers of granular backfill and reinforcing strips with a modular pre-cast concrete facing. Using a crew of five and standard construction equipment, contractors can install 750-1,000 square feet of wall face per shift, using a simple, repetitive construction procedure. This procedure repeats until the design height is reached.
