WPA 2010 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. It expands up to 900% when in contact with water to form a positive seal against the concrete surface.
WPA 2010 will shrink back to its original size when it dries and will re-expand on wetting. WPA 2010 is used for the sealing of low movement and static construction joints for both horizontal and vertical applications including cold joints, wall-to-base connections, penetrations, and sealing of openings and interface sections between existing and new concrete surfaces.
