Bentonite Cetco Hydraul-EZ®
HYDRAUL-EZ is a high-yield, 200 mesh sodium Wyoming bentonite blended with a special dry polymer additives making it ideal for HDD boring. HYDRAUL-EZ is certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.
When drilling with bentonite, a protective “filter cake” is formed on the borehole wall reducing the level of soil permeability and increasing stability. The circulating bentonite slurry removes the drilled cuttings bringing them to the surface. The bentonite mixture also exerts hydraulic pressure preventing any collapse of the walls even when the excavation is below the water table. Bentonite slurry also acts as a lubricant for drilling tools.
