Product Description

Product Description

Type PN Bentonite strip is a kind of water swelling waterstop. It is also called putty type waterstop.  Type PN bentonite waterstop is new type of building waterproof material that is made of polymer, inorganic water swelling materials, rubber and additives being extrusion by machine without vulcanization process. This kind bentonite waterstop will produce 2-3 times the expansion deformation after soaking. So it can fill the construction joints to prevent leakage thoroughly. And its hydrophilic swelling has not lost after repeated long-term expansion. Our bentonite waterstop use non-toxic and pollution-free materials. It will do not harm to people and environment. In addition, our bentonite waterstop with good corrosion resistance can be used in many underground constructions without damaged.
