Bentonite-Geotextil is a proven waterproofing membrane ideal for vertical and horizontal foundation surfaces. It incorporates the high-swelling and self-sealing properties of sodium bentonite to form a monolithic, low permeable membrane to protect the structure from water ingress. Bentonite-Geotextil contains zero VOCs and can be installed on green concrete in almost any weather condition. Bentonite-Geotextile combines the proven waterproofing technology of a bentonite geotextile composite with a high-strength polymer liner. It is designed for projects that require additional chemical resistance and low water vapor permeability.
