Decora PVC Waterstopper provides a durable and watertight solution for sealing construction and expansion joints in concrete structures. Manufactured from premium-grade PVC compound, it prevents water seepage through joints exposed to hydrostatic pressure—ensuring complete waterproofing and structural integrity.
Our PVC waterstopper is suitable for horizontal and vertical joints in all types of water-retaining and water-excluding structures, such as basements, retaining walls, dams, bridges, tunnels, and water tanks. With outstanding flexibility, chemical resistance, and tensile strength, Decora’s waterstoppers maintain performance even under extreme conditions.
Available in multiple profiles—Center Bulb, Dumbbell, Ribbed, and Flat Rib—the product accommodates structural movements while maintaining a secure bond with concrete.
Each profile is precision-engineered for easy on-site installation, and factory-fabricated junctions can be supplied upon request for complex designs.
