WATERSTOP® XP is the next generation of waterstop that expands upon contact with water to form a positive seal to stop water ingress through cast-in-place concrete construction joints and around pipe penetrations. Through the use of the patented XP technology, WATERSTOP® XP is proven effective in a wide range of contamination environments, including high-saline conditions. Its flexible design also makes it effective for both horizontal and vertical joints.

WATERSTOP® XP is manufactured in lightweight, flexible coils and designed to replace passive PVC/rubber dumbbell waterstops — eliminating the requirement of special pieces, split forming and seam welding.
