Bentonite Waterstop

Doron Bentonite Waterstop is a flexible strip concrete construction joint waterstop that provides a positive seal by gradually expanding when in contact with water. Bentonite Waterstop is an active bentonite based waterstop that is designed to replace conventional passive PVC dumbbell waterstop, thus eliminating the requirement of split-forming and product seam welding. The key to Doron Bentonite Waterstop effectiveness is its modified sodium bentonite content which provides superior expansion to seal and fill voids.
