Water-Swellable Strip, Adjustable Expansion Ratio, for Various Conditions

The water-swellable waterstop strip gradually expands in volume upon contact with water, filling gaps in concrete construction 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 after expansion and is suitable for regular and flat construction joints. The PN(BW) Type (black) is a soft, sticky material that can conform to irregular surfaces and is suitable for pipe joints, complex joints, and other applications.

Upon receiving clear and complete inquiry information (such as drawings, specifications, and quantities), we typically provide an initial quotation or proposal within 24 hours. For complex projects, we will communicate the required time with you promptly.

As a comprehensive solution provider, our product line also includes: waterstops (PVC waterstops, rubber waterstops, etc.), laminated rubber bearings for bridges, rubber pads, pot bearings, spherical bearings, seismic isolation bearings, bridge expansion joints, as well as sealants (polyurethane, polysulfide) and flexible pipes for building isolation. We are committed to providing various key components for civil engineering.
