PVC Water Stopper
PVC Water Stopper are flexible Plastic strips which provide a physical barrier to Water at concrete joints, mostly in basements, Water retaining structures like Water tanks, Swimming pools, structural foundations & other below ground level constructions. Water stopper are also termed as Water Bars, seals construction joints. A typical PVC water stopper have two identical half on both sides of a central bulb. These additional extensions are provided with the aim of increasing path length for water entering behind the edge of water Stopper.
Compounding of PVC Water Stopper:
PVC Water Stopper are manufactured at Dessawala Rubber Industries from Anti-Ageing customized plastic compound with PVC as a base polymer and exhibiting required properties like High Elasticity & Tensile Strength, Immune to Corrosion, Excellent weather resistant, Unaffected by acids, alkalis, metals salts and other chemicals, Lower water absorption, Withstand high Hydrostatic pressure, Can bear shocks of heavy turbines, Earthquakes, Floods.
Application in Construction Industry:
PVC Water Stopper act as a sealant at RCC Masonry concrete joints & prevent any seepage of water in or out through joints. PVC Water Stopper withstand expansion or contraction movement at joints and take care of any deflection or displacement arising due to change in temperature, differential settlement of foundation, Geo disturbances causing Seismic forces like earth quack, thus eliminating danger of cracks.

PVC Water Stopper jointing procedure
• Water Stopper can be joint on site with a simple electrical heater blade.
• Water Bars of same width & design should be sharply levelled at edges using a knife.
• Turn on the Electric Heater Blade and wait will it become hot.
• Place the water stoppres on both sides of heater blade & press it until it melts but without burning.
• Remove the heater blade upward.
• Joint the molten end quickly & hold them together firmly for approximately 20-30 seconds.
