Waterstopper is a product made from virgin PVC designed for use in concrete construction joints, one side of which is subject to hydrostatic pressure. The Waterstopper is used as a barrier within the joint to prevent the passage of liquid through or across the joint. It is designed to accommodate lateral and transverse movements that cause the joints to open or close or misalign.
Waterstopper is designed to stop the ow of liquids through or across the joints in concrete construction, if properly installed. Some of the structures requiring Waterstopper include swimming pools, storage tanks, roof and or slabs, parking decks, bridge decks and abutments, foundations, basements, retaining walls, dams, locks, sewage and water treatment plants, water reservoirs, canals, tunnels, elevator pits, and all concrete structures requiring tight joints.
