Bentonite waterstop is a kind of hydrophilic water sealing product coming with incomparable durability and higher water absorption no less than 300%. Unlike traditional clay based waterstops, this one utilizes rubber as base material to form a controlled, moisture active sealant - that means the bentonite waterstop will not expand to point losing much of integrity even being washed away by water during continually expansion.
- 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.
