PVC Waterstop
Product details
PVC waterstop, also termed as PVC water bar, PVC seal construction joint, is embedded in construction joints or movement joints to provide a physical barrier to water. It is made from high grade polyvinyl chloride, special resin and some chemical additives, such as plasticizers and stabilizers. The product goes through the process of mix, extrude. It has many species and specifications. The waterstop should be positioned accurately to prevent deflection or misalignment during concrete placement. It is fixed to adjacent reinforcing steel through outer flanges of the waterstop. The waterstop is used in various concrete structures, such as dam, canal, water reservoir, aqueduct, tunnel, culvert and so on.

Features
Good tensile strength, elongation capability, inherent elasticity and waterproof impermeability capability.
High resistance to acid, alkali, corrosion, ozone, seawater, natural salt, diesel oil, chlorinated water and other waterborne chemicals.
Not susceptible to fatigue deterioration as with metal or rubber.
No electrolytic action with surrounding metals.
Withstand the expansion and contraction movement of the joints, hydrostatic pressure.
Heat weldable in conjunction with electric splicing irons.
Not arise deflection or displacement caused by temperature change or different settlement of foundation.
Not affected by weather, low temperature.
Can bear shocks of heavy turbines, Earth quakes, Floods.
Supply in roll, easy to handle, transport and install.
Flexible, durability, can be bent around corners or formed in curves as required, can be welded in site.
Long life.
Application
PVC waterstop mainly used in construction joints and movement joints to prevent water leakage and seepage, such as the following
Ideal for portable water tank, water and sewage treatment facility, foundation, basement, subway.
Suitable for dam, canal, water reservoir, aqueduct, tunnel, culvert, parking deck, bridge deck, abutment, elevator pit, roof, floor slab.
Primary and secondary containment structure.
Used for swimming pool, road embankment, retaining wall, underground facility, stadium, storm drain.
Storage and package
PVC waterstop should be stored in shade and dry environment, away from sunlight, water, moisture, high temperature, acid, alkali, oil, organic solvent, heat source. The product should be placed vertically, not be pressed by heavy things. The temperature range of storage place should be -10°C to +30°C, relative humidity is in the range of 40% to 80%.
Package: 20 m/roll.
