Waterman Excavating is an excavation contractor based out of Adams. They provide wet soil mixing and dewatering as well as other services.
The excavator digs down to design depth, or bedrock, for the first cut. The excavator is then lifted and moved along the trench guide walls to continue the trench with successive cuts as needed. The trench is kept filled with slurry (usually a mixture of bentonite and water) at all times to prevent collapse. Once a particular length is reached, a reinforcing cage is lowered into the slurry-filled pit and the pit is filled with concrete from the bottom up using tremie pipes.
