Greenseal Bentonite KP Waterstop Hydrophilic Construction Joint Waterstop 19MM x 25MM x 5M

Greenseal Bentonite KP Waterstop is a hydrophilic sealing strip formulated with high-grade sodium bentonite and elastomeric polymers. It is specifically designed for construction joints in reinforced concrete structures. Upon contact with water, the KP Waterstop swells to form a flexible, watertight barrier, preventing water leakage through cold joints and construction gaps. With strong swelling capacity, durability, and chemical resistance, it ensures reliable long-term joint protection.
