CETCO bentonite products are used to contain contaminated groundwater, dewater excavations and stabilize dams, levees, and other similar structures. Bentonite slurry has a slightly higher specific gravity than water, creating a positive hydrostatic head that stabilizes the sides of the trench to hold soil particles together and prevent collapse. The backfill material, some of which may contain soil, bentonite and cement, provides an impervious barrier and over time will set to final form.
