Product Description
PVC Water Stopper

PVC Water Stopper provides water barrier across all joints in concrete structures by placing Water Stops into edges of adjacent concrete components. Water Stops are essential for use in all water retaining and water excluding structures, being capable of withstanding water pressure from either internal or external face. PVC Water Stopper profiles are made of extruded Polyvinyl Chloride (PVC) conforming to IS:12200 and IS:15058. Material for Water stops is clean, homogenous and free from porosity and other imperfections.
Water Stoppers are/have
• corrosion resistant
• excellent weather resistant, suitable for tropical climate.
• good mechanical strength
• high elasticity
• ability to withstand high hydrostatic pressure

Water stoppers work as Watertight seal, allow safe passage of seepage water & can bear shock of heavy turbulence, flood or earthquake. The wings of Water stop are provided with corrugations/bulbs to achieve good bond. In expansion joints, they are provided with hollow center bulb.
