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. Comparing with bentonite waterstop and butyl rubber waterstop, this one has following characters:

Features & benefits:

• High watertight properties - once exposed to water, PZ waterstop will expand one 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.

Applications:

• Pipe penetration.

• Water reservoirs.

• Settling pond.

• Deformation and concrete construction joints of civil engineering.

• Water conservancy and hydropower projects, etc.
