Bentonite Waterstop Swellable for Tunnel and Culvert Joints

The water -swellable waterstop strip gradually expands in volume upon contact with water, flling gaps in concreteconstruction joints, pipe joints, and other locations, forming a physical water barrier to achieve water sealing.

The PZ(BF) Type (red) is a preformed material with certain hardness and elasticity. Its shape remains stable afterexpansion and is suitable for regular and flat construction joints. The PN(Bw) Type (black) is a soft, sticky material thatcan conform to irregular surfaces and is suitable for pipe joints, complex joints, and other applications
