VOLCLAY^® BENTONITE SOIL SEALANTS

VOLCLAY soil sealants are granular sodium bentonite products manufactured by CETCO that provide economical, low permeability soil liners for a wide variety of containment applications.

Function

When VOLCLAY bentonite soil sealants are mixed with soil and hydrated, it expands to fifteen times its volume, forming a mechanical bond with surrounding soils and filling the voids between the soil particles. This creates a barrier that effectively stops further seepage through the soil, and decreases the permeability of soil by several orders of magnitude. Bentonite can withstand dessication, hydration and freeze-thaw cycling without losing its sealing ability.

Applications

VOLCLAY bentonite soil sealants can be utilized for a number of different applications including reservoirs, secondary containment, agricultural waste containment, ponds, slurry trenching, or wastewater treatment lagoons, just to name a few. Where there is erosion potential from run-off, inlet flow, aerators or other factors, the soil mixture should be protected by a cover layer .

Features and Benefits

• Because of the high swelling capacity of VOLCLAY bentonite soil sealants, only a small amount is needed to reduce the hydraulic conductivity of the onsite soils.

• VOLCLAY bentonite soil sealants are offered in a a variety of formations, allowing for use in a wider variety of applications.

• With access to the largest bentonite reserves in the world, CETCO is able to provide the most consistent and highest quality soil sealants available.

• By offering three processing locations across the United States, shipping costs can be substantially reduced.
