Solutions To Water Containment Needs - Bentonite Waterstops
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.
