Transit Mix Soil-Bentonite Slurry Cutoff Wall

Project Location: Pueblo, Colorado

Project Description:

Hall-Irwin was hired as the design-build contractor to construct a soil-bentonite cutoff wall (slurry wall) utilizing soil-bentonite backfill. The project team dug down to bedrock keying into it up to 9 FT. This 9 FT key was required where “fractured” bedrock was encountered. Digging below the fractured bedrock ensured the success of the wall, which allowed the successful sealing off ground water. Hall-Irwin Corporation field personal worked with the onsite engineer to assure that the depth into bedrock was such that we successfully keyed deep enough into bedrock to seal the wall without going so deep into bedrock that the cost to the owner would be cost prohibitive.
