Audited Supplier 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.
The capacity expansion rate of waterstop is up to 500%.
Water Stop Bentonite Waterstop will expand after soaking, and the impermeability is better.
After repeated long-term expansion, the hydrophilic expansion of Water Stop Bentonite Waterstop did not disappear.
Water Stop Bentonite Waterstop is resistant to corrosion, aging and acid and alkali.
Water Stop Bentonite Waterstop has high tensile strength and tear resistance.
Water Stop Bentonite Waterstop is non-toxic and pollution-free.
Water Stop Bentonite Waterstop has high expansion rate and strong self-healing function.
The surface of waterstop shall be clean and smooth without impurities.
Water Stop Bentonite Waterstop is easy to install and replace.
Waterstop is an economical choice with lower cost.
