Steel-edge waterstop is a modification of traditional rubber waterstop with steel plate rings being inserted into the middle of vulcanized rubber. High liquid-tightness and high absorption of shear movements make the steel-edge waterstop a recommended choice for expansion, contraction joints and other construction fields with high pressure and structure variable.
Once the structure sedimentation, concrete shrinkage and creep occur, the rubber parts of steel-edge waterstops will be elongated and thin to adjust to these deformations without affecting the adhesion between steel plates and the rubber part, between steel plates and the surrounding concrete. In this way, the steel-edge waterstops are able to withstand greater tension and torsion than traditional waterstops; meanwhile, it effectively prevents concrete loosen, breaking off and the form of leaking cracks.

Pz waterstop is a new type hydrophilic watertight product manufactured of quality vulcanized rubber and other additives, which make it expansible with physical properties of rubber. Comparing with bentonite waterstop and butyl rubber waterstop, this one has following characters:
Features & benefits:
high watertight properties - once exposed to water, pz waterstop will expand one to five times to fill all irregular surfaces, holes and spacing of surrounding concrete. Meanwhile, if the construction joints are displaced which will result in oversized gaps beyond elastic range of waterstops, traditional waterstop will lose its effect of water-proofing, but our pz waterstop still performs great by continual swelling.
much stronger taking advantages of cross-linked chemical structure at the atomic level.

smaller size but uncompromising water swelling property.
eliminate elastic fatigue caused by excessive compression.
excellent water resistance, chemical resistance and anti-aging property.
easy and quick to install.
slow expansion type is also available as your request.
Applications:
pipe penetration.
water reservoirs.
settling pond.
deformation and concrete construction joints of civil engineering.
water conservancy and hydropower projects, etc.

Rubber waterstop, made of quality SBR (styrene butadiene rubber), neoprene rubber or natural rubber, is one of the widest types for concrete structure to prevent liquid leaking in or out. Generally, designed to be cast in the concrete, rubber waterstops are ideal for applications where high physical properties of rubber are required. For example, reservoirs, dams and other water retaining or excluding applications with high movements or water pressure.
Features & benefits:
Two types of rubber waterstop, the first one is centerbulb type and the second is dumbbell type

?High elasticity.
?High elongation.
?Excellent high movement accommodation.
?Capable to withstand high hydrostatic head.
?Adjust for subsidence and seismic movements.
?Hot vulcanized site joints.

Applications:
?Ideal for high movements joints.
?Water containments.
?Water excluding.
?Tunnels and civil engineering structures.
?Water and waste treatments.
?Dams, reservoirs, and spillway.
?Chemical areas.
?Irrigation canals, sea walls and culverts.

Rubber waterstop - dumbbell type
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.

Rubber waterstop – center bulb type
?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.
Installation:
All the rubber waterstops are designed to cast in the concrete as an integral joint sealing system. Pre-fabricated waterstops are also supplied to reduce site jointing.
Materials properties
SBR and neoprene rubber, as the most common materials for rubber waterstop manufacturing, are used extensively in United States and the worlds. The SBR water stop is preferred for water containment, while neoprene rubber waterstops are recommend for applications of sewage disposal or chemical industries. As your request, natural rubber, EPDM, Nitrile and Silicone waterstops are also available
