    PVC Waterstops
    PVC Waterstop is a conventional waterstop that can be used in a variety of applications. The main usage is to prevent the passage of liquids in concrete joints in many different projects such as Dams, Tunnels, Water & Wastewater Treatment Plants, and other liquid retaining structures.
    Typical Properties
    water absorption %: 15
    tear resistance psi (kg/cm2): 300 (21.1)
    specific gravity: 1.38
    tensile psi (kg/cm2): 2000 (140.61)
    elongation %: 350
    ozone resistance: no failur
    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
