PVC Water Bars & associated Products for Construction Industry
Water Stops 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. A typical water stop have two identical half’s on both side of a central bulb. These additional extensions are provided with the aim of increasing path length for water entering behind the edge of water stop.
Compounding of Water Stops:
Waterstops are manufactured 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 Hydro static pressure, Can bear shocks of heavy turbines, Earth quakes, Floods.
Application in construction Industry
PVC Waterstops acts as sealants at RCC Masonry concrete joints & prevent any seepage of water in or out though joints.
Water stoppers 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.
Selection of appropriate Waterstop:
Waterstop installation procedure:
Water Stopper is tied to steel frame works or small eyelet by means of small wires (same being depicted in the adjacent figure), certain metal clamps meant to grip the water stop seal and keep it in proper position.
Firstly one half of the waterstop is embedded in the concrete leaving the second half extended. Second half is also embedded leaving the center bulb free for expansion and contraction movements.
Area of Application:
Precautions taken during water stop installation
