SANDHYAFLEX PVC Water Stopper is a high-performance sealing strip used in construction to prevent water leakage through concrete joints. It acts as a watertight barrier in structures exposed to water pressure like tanks, dams, and basements. (sandhyaflexrubber.com)
It is a flexible PVC (Polyvinyl Chloride) strip embedded inside concrete joints to stop water seepage.
Also known as Water Bar
Installed during concreting stage
Creates a continuous waterproof seal across joints (sandhyaflexrubber.com)

Application : Main Uses of PVC Water Stoppers Sealing Construction Joints Water stoppers are embedded at the point where two concrete sections meet (construction joints) to block water from passing through those joints. Waterproofing Basements & Foundations In belowground structures like basement walls and foundation slabs, they help keep groundwater out, ensuring dry interiors. Water Tanks & Reservoirs Used in water retaining structures, they prevent leaks so stored water doesn t escape from joints in the concrete. Swimming Pools and Tanks They keep the pool structure watertight by sealing the joints in the concrete shell, preventing leaks. Expansion and Movement Joints PVC water stoppers can flex and adjust with concrete movement (from temperature changes or settling), maintaining the seal even if the structure shifts slightly. Tunnels, Bridges, Dams & Retaining Walls In large civil projects like tunnels, bridges, dams and retaining walls, they stop water penetration under pressure critical for structural durability and safety. Industrial & Utility Structures Used in industrial buildings, sewage plants, power stations, etc., where joint leakage must be controlled. How It Works A PVC water stopper is placed in the formwork before concrete is poured. Half is captured in one concrete pour
