Product Description


Bentonite is a swellable clay waterproofing compound that is glued or nailed in strips into construction joints. Known as a hydrophilic waterstop system, bentonite expands up to sixteen times its dry volume when it comes into contact with water, forming a compression seal in concrete joints. Bentonite's ability to swell enables it to fill small cracks and voids in concrete, preventing the ingress of water around joints. And since clay is a natural material, bentonite is a popular waterstop choice for potable water applications.

Advantage Rubber swellable waterstops:

1.High tensile strength, high tear resistance.

2.High break elongation rate, Less compression set.

3.Low fragility Temp, anti-aging ,anti-corrosion.

4.Easy installation, supply with various joints.

5.Can be Customized according to construction and projects design.
