Description of pvc waterstop belt :
pvc waterstop belt being embedded 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.
Features of pvc waterstop belt:
1.High tensile strength.
2.Superior elongation capability.
3.Excellent inherent elasticity and impermeability
4.High resistance to acids, ozone, seawater even diesel oil.
5.Extremely alkalis, chlorinated water and other waterborne chemicals resistant.
6.Not susceptible to fatigue deterioration as with metal or rubber.
7.High quality meet even exceed the industrials standard.
8.Never discolor concrete.
9.No electrolytic action with surrounding metals.
10.Capable to withstand hydrostatic pressure.
11.Heat weldable in conjunction with electric splicing irons.
12.Withstand the expansion and contraction movement of the joints.
13.Capable to taking care of any deflection or displacement arising caused by temperature changing or differential settlement of foundation.
14.Supplied in coils for easy handling with high flexibility.
15.Easy to install by tethering the outer flanges of the PVC waterstop to adjacent a reinforcing bars.
Different types of pvc waterstop belt: Customized sizes, types and colors.

We exported to Kenya 5400m blue concrete joint pvc waterstop belt:
There are also some general pvc waterstop belt types from Vietnam, blue and yellow colors. Welcome your inquiry.
Main waterstops for your reference:
1.HDPE waterstop belt is also a kind of extruded plastic watertight seal similar to PVC waterstop, however, this one comes with harder and stronger structure, higher abrasion ability as well as can withstand elevate and low temperatures. Additionally, high resistance to hydrocarbon, acids, oils and fuels makes it ideal for applications in fuel and hydrocarbon areas.
2.TPV & TPER waterstop belt is manufactured from recycled thermoplastic elastomeric rubber and plastic materials. Comparing with traditional PVC waterstop, this one has the characteristics of high resistance against temperature, weather as well as chemical liquids such as ketones, esters, glycols, alcohol, ozone, oils, solvents, hydrocarbon, etc.
3.Rubber waterstop belt is a hydrophobic water sealing products capable to withstand high water pressure and absorb high movements of concrete joints. Generally, SBR, neoprene rubber and natural rubber are the main materials for manufacture of rubber waterstops, but as your request, other materials are also available such as EPDM and silicone, etc.
4.Steel-edge waterstop is composed of central rubber part and steel plate rings which are inserted into the rubber. This special design allows the waterstop enable to subject to shear joint movements, structure sedimentation, concrete shrinkage and creeps, etc.
Stainless steel waterstop, coming with excellent corrosion resistance, prevents any passage of corrosive and aggressive fluids. Meanwhile, this waterstop is extremely resistant to fire, high temperature and ozone, so if you need waterstops for ozone contractor structures or chemical industries, this one is your best choice.
5.Reinforced waterstop is designed to meet specific needs of strength or water-proofing properties. As your requirements, waterstops can be reinforced with internal steel plates, external steel bars and expansible strips.
6.PZ waterstop is mainly composed of high quality vulcanizate rubber which makes it has physical properties of rubber in addition to expansible ability. With smaller size, the PZ waterstops come with excellent liquid resistance, stronger structure without elastic fatigue.
7.Bentonite waterstop, adds expansible bentonite to rubber base material to form a hydrophilic watertight products with water absorption no less than 300%. Meanwhile, it has great expansion control ability to avoid losing the integrity of strip waterstops.
8.Butyl rubber waterstop, as its name implies, is mainly composed of butyl rubber materials as well as other additives such as mastic or expanded clay. Also as a kind of hydrophilic waterstop, it will expand when exposed to water and other water solutions and form a permanent compression seal in non-moving joints.
9.Mastic waterstop, different from all above strip waterstops, is a hydrophobic self-component, self-sealing product that can withstand all types of weather and harsh temperatures.
