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.
Features & benefits:
- Quality sodium bentonite clay and rubber materials.
- Moisture activated.
- Strong, durable with high cost effectiveness.
- High water absorption with excellent compression seal.
- High expansion control ability for preserving its integrity.
- Controlled internal pressure in surrounding concrete to avoid spalling and cracks.
- Withstand high water pressure.
- Capable to self-healing.
- Easy and fast to transport and install.
- Easy to joining.
- Non toxic
