Product & Usage
Concrete Joints Rubber Hydrophilic Swellable Bentonite Waterstop
Concrete Joints Rubber Hydrophilic Swellable Bentonite Waterstop is an absorbent strip used to seal and waterproof concrete joints.

It is a new type of waterproof material, water stop, waterproof effect is more reliable than ordinary rubber. In contact with water the waterstop strip will swell approximately 150%-600 % of its original dry volume, the expansive clay mass will seal the cracks and small voids in the joint.
