Product Description

Product Description

Bentonite waterstop is a kind of hydrophilic water stop 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 water stop will not expand to point losing much of integrity even being washed away by water during continually expansion.
