Hydrophilic waterstop bar 150%-600% expansion rate waterstop strip

Product Description Hydrophilic 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.
