Rubber Hydrophilic Swellable Bentonite Waterstop
Product Description
A thick sectioned, hydro-expansive waterstop for preventing water entry through joints in concrete sub-structures.The swellable polymer/ butyl rubber waterstop strip expands in contact with water, and when fully encapsulated by poured concrete, will form a seal against concrete faces.
The seal resists hydrostatic pressure, stopping water from entering sub-structures. Developed to provide higher performance than conventional bentonite or swellable rubber waterstops.
PN Unvulcanization Waterstop
PN unvulcanization waterstop is a kind of water swelling waterstop. It is also called putty type waterstop. PN unvulcanization 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 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 products use non-toxic and pollution-free materials. It will do not harm to people and environment. In addition, our PN unvulcanization waterstop with good corrosion resistance can be used in many underground constructions without damaged.

Properties of PN Unvulcanization
PZ Waterstop
PZ waterstop is a new type hydrophilic watertight product manufactured of quality vulcanized rubber and other additives, which make it expansible with physical properties of rubber.
Features:
* High watertight properties - once exposed to water, PZ waterstop will expand one up to five times to fill all irregular surfaces, holes and spacing of surrounding concrete. Meanwhile, if the construction joints are displaced which will result in oversized gaps beyond elastic range of waterstops, traditional waterstop will lose its effect of water-proofing, but our PZ waterstop still performs great by continual swelling.
* Much stronger taking advantages of cross-linked chemical structure at the atomic level.
* Smaller size but uncompromising water swelling property.
* Eliminate elastic fatigue caused by excessive compression.
* Excellent water resistance, chemical resistance and anti-aging property.
* Easy and quick to install.
* Slow expansion type is also available as your request.
