Water Stopper A Grade

Description

A "Water Stopper A Grade" typically refers to premium-grade, flexible polyvinyl chloride (PVC) strips (also known as waterstops) used in construction. Cast directly into concrete, they create a watertight physical barrier across joints to stop water seepage and leaks. Why "A Grade"? "A Grade" signifies that the material is extruded using 100% pure PVC compounds rather than low-cost recycled plastics. This distinction is critical for durability: High Elasticity: It can stretch and absorb structural settling or expansion without snapping. Chemical Resistance: It withstands underground salts, chlorides, and mild acids without degrading. Longevity: It remains highly flexible across extreme temperatures, preventing the strip from becoming brittle over time Uses: These barriers are primarily embedded at the intersections of two concrete pours where water is most likely to penetrate. Common applications include: Underground basements and retaining walls Water tanks, swimming pools, and dams Elevator pits and underground garages Expansion and construction joints Key Features: Good resistance of water seepage. Several sizes (6” to 12”) are available. Perfect to use in water retention buildings.
