Product Description

Expanding swelling rubber water stop strip
Description
Expanding swelling hydrophilic bentonite rubber water stop strip is an absorbent strip used to seal and waterproof concrete joints. Water swelling strip is commonly made of natural sodium bentonite clay and synthetic rubber. Both the modifiedsynthetic rubber and the bentonite expand in the joint when exposed to moisture. 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 approximately150%-600 % of its original dry volume, the expansive clay mass will seal the cracks and small voids in the joint.
