Hydrophilic construction joint 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. 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.

HDPE Waterstop

Why You Need HDPE Waterstop In Fuel Areas? 

HDPE waterstop, also a kind of plastic waterstop similar to PVC waterstop, are made of quality high density polyethylene materials with high chemical resistance when exposed to hydrocarbons, acids, hot petroleum oils, solvents and diesel fuels, etc. However, the HDPE waterstop is harder, more abrasion and heat resistant than PVC waterstops.

Features & benefits:
  • Strong and durable.
  • High resistance to elevate and low temperature.
  • Excellent anti-abrasion.
  • Superior resistance to chemical liquids, hydrocarbons, acids, solvents, oils, fuels, and other non-polar fluids, etc.
  • Resistant to oxidants and reducing agents.
  • Not prone to swell and be flexible.
  • Easy to butt-weld to form a continuous diaphragm. 
Application:
  • Perfect for primary and secondary containment structure.
  • Sewage treatment facilities.
  • Fueling areas.
  • Mining and refineries facilities.
  • Chemical plants
  • Liner application
Installation:
In conjunction with brass eyelets, punched flanges or hog rings, tie wires to surrounding reinforcing bars to prevent the waterstop from displacing during the concrete pour. For changing directions, pre-fabricated waterstops are recommended.
