WPA Hydrophilic Waterstop

WPA Hydrophilic Waterstop is a new generation, selfadhesive, 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.
