Main types:
Dumbbell type
Dumbbell type water stops, with flat web section, are ideal for construction and partial contraction joints with little or no movements.
Center bulb type
Center bulb type waterstop, as its name implies, features its center bulb which makes it ideal for contraction and expansion joints including high lateral, transverse and shear movements. Meanwhile, it is perfect for withstanding the subsidence of the joints.
As your request, other types including ribbed type, splitting type, base type or capping type can be made to your order.

PVC waterstop, 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.
The 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 as shown follow.
Installation:
In general, the right way of waterstop installation determines the performance in preventing waters and other waterborne chemicals. Any deflection and misalignment should be avoided - that means the best way of installation is to fix the PVC waterstop to the surrounding steel. So for easy installation, three economical methods are provided by our company as shown in the picture:
- Punched flanges
- Grommets
- Hog rings or clamps

What Types Of Waterstop Can We Supply?
Our company can supply two main ranges of watertight products - that are waterstop series and strip waterstop series as shown in the pictures. Waterstops series includes PVC, HDPE, TPV, rubber, steel-edge, stainless steel as well as reinforced waterstops. While, the PZ, bentonite, butyl rubber and mastic waterstops are the main compositions of strip waterstop series.
PVC waterstop, as the most common watertight type, features high tensile strength, elongation capability and high resistance to acids, ozone, alkalis, diesel oil, chlorinated water and other chemical liquids. Meanwhile, they will not discolor the concrete or support even produce electrolytic action with surrounding reinforcing steels.
HDPE waterstop 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.
TPV & TPER waterstop 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.
Rubber waterstop 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.
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.
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.
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, thePZ waterstops come with excellent liquid resistance, stronger structure without elastic fatigue.
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.
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.
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.
We'll offer best products and service, good price to our clients forever!
