WPA Hydrophilic Waterstop

Hydrophilic Self-Adhesive Water Stop

WPA Hydrophilic Waterstop is a new generation, self-adhesive, high performance acrylic polymer base expanding hydrophilic water-stop.

It’s designed to stop water ingress through cast in place concrete structures, and expand when in contact with water to form a positive seal against the concrete surface. WPA Hydrophilic Waterstop will shrink back to its original size when it dries and will re-expand once wet.

WPA Hydrophilic Waterstop is used for sealing low-movement and static construction joints in both horizontal and vertical applications, including cold joints, wall-to-base connections, penetrations, sealing of openings, and interface sections between existing and new concrete surfaces.
