PVC Waterstop - The Best Solution to Concrete Construction
PVC waterstop, being embed in the concrete joints, acts as a continuous watertight diaphragm to prevent any seepage of liquids in constructions joints which are subject to hydrostatic pressure. It is designed for expansion or contraction joint; meanwhile, it can accommodate lateral and transverse movements which make it capable to suit the moving joints.
PVC waterstop is extruded form an elastomeric plastic material including high grade polyvinyl chloride, special resin and some chemical additives such as plasticizers and stabilizers. The high material makes PVC waterstops unsurpassed with a variety of features and benefits.
Shapesof PVC Waterstop
1. Plain web
Suitable for construction, kicke and partical contraction joints, where no shear movement is possible.
2. Centre Bulb
Suitblefor ubsidence, contraction expension joints, including high movement joints
Typical Application of PVC Waterstop
1.Agriculture:Dams, Canals, Aquaducts, Large Reservoirs, Irrigation Projects.
2。Public Utilities:Water Tanks, Swimming Pools, Tunnels, ConcreteRoads, Water Filtration Plants, Sewarage Disposal System, Neutralization Tanks, Bridges,Roads,
Embankments,Municipal Hydraulic Projects, Clarifiers.
3.Buildings:Basements & Foundations Floor Slabs,Terraces, Concrete Runways, Retaining Walls, Overhead & Underground,Water Tanks, Multistoried Buildings.
4.Industries:Fertilizer, Steel, Effluent Treatment Plants,Thermal Power Stations, Atomic Reactors, Shipyards & Docks, Cooling Towers.
