PVC Water Stopper

PVC Water Stopper IS 15058 Manufacturers:


DEESA FLEX 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

Selection of appropriate Water Stopper:

1.Ribbed Type– multipurpose water Stopper design, used where the differential settlement of poured concrete is expected and a firm grip in concrete is desired.

2.Dumbbell Type– Greater variation in temperature causes expansion or contraction of joints, Dumbbell type water Stopper is suggested for these sites.

3.Kicker (Surface) Type– these are externally placed and are used where embedded types cannot be used due to the interference of steel reinforcement.

Installation procedure:

Water Stopper are tied to steel framework through eyelets by means of small wires (same being depicted in the adjacent figure), certain metal clamps meant to grip the water Stopper seal and keep it in the proper position. Firstly one half of the water Stopper is embedded in the concrete leaving the second half extended. The second half is also embedded leaving the center bulb free for expansion and contraction movements.

Area of Application:

Public Utilities: Bridges, Road Embankments, Tunnels, Water Tanks, Swimming Pools, Water Filtration plants, Sewage Plants, Clarifiers, Dams, Canals, Aqueducts, Reservoirs, Irrigation Projects Cooling Towers.

Building: Basements, Foundations Slabs, Masonry Joints, Terraces, Retaining Walls, Overhead & Underground Water Tanks, Skyscraper.

Industries: Chemical Plants, Fertiliser Steel, Waste Treatment Plants, Thermal & Hydro Power Stations, Atomic Reactors, Shipyards & Docks.

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.

Our premium quality "DEESAFLEX" Brand Water Stopper is available in numerous designs/sized are exported worldwide.
We also offer Water Stopper with ISI marking & material confirming BIS Standard IS:15058-2002 & Test Report.

PVC Water stopper with Excellent Elasticity and Corrosion Resistance

PVC Water Stopper, also called PVC water stopper seal or PVC water stopper belt, is manufactured from superior grade polyvinyl chloride resin and various chemical additives by the process of mixing, granulating and extrusion. It is used to prevent leakage and permeation in construction joint by taking full advantage of polyvinyl chloride resin property of good elastic deformation. It is highly resistant to corrosion and it has excellent durability. PVC water stopper are mainly used for tunnels, bridges, storage tanks, water and waste water treatment plants, dams, culverts and other places.
