Product Description

20 X 30mm Bentonite Waterstop Used for Concrete Joint Waterproofing20 X 30mm Bentonite Waterstop Used for Concrete Joint Waterproofing
Type PN Bentonite waterstop 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.

Bentonite waterstop with expanded metal

Bentonite waterstop with expanded metal is a new type water sealing product. The added expanded steel mesh (or nylon mesh as your request) effectively enhances the tensile strength of the waterstop and improves the overall construction quality.

Bentonite waterstop with grouting pipe

The perfect match of bentonite waterstops and grouting pipes extremely improve the performance of the water-proofing capability. Once the leakage of water occurs, you can plug the crack through pouring chemical grout into the pipe, instead of slotting and drilling a hole on the construction surface.
