GEOCHEM ENGINEERING’s Bentonite Liner is a dual layer waterproofing consisting of PE film or HDPE membrane or PVC membrane, sodium bentonite, and a non woven geotextile as protective layer. The membrane layer provides the first level of waterproofing, while the bentonite’s self-sealing capabilities ensure positive puncture protection under hydrostatic conditions. The geotextile fabric protects the cpmposite from direct installation of shotcrete or concrete walls.
it is designed for use below-grade applications and is equally effective in installations where the waterproofing is pre-applied prior to pouring of the concrete or when used for standard applications.
Bentonite liner can be used in both vertical and horizontal applications.
