Product Description
Rubber Waterstops - SBR, Neoprene Or Natural Rubber
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.
Material: NBR,CR,SBR,EPDM,HNBR,ACM,IIR,NR,EP,Silicone etc.
Usage:Waterproof stoppers are used for construction joints in subway, all kinds of pools, sewage treatment plant, tunnel, culvert, etc.
Features & benefits:
- Expansible strip can expand when it is in touch with water.
- Adapt the deformation of concrete.
- High elasticity and tensile strength.
- Can arise compression deformation under various loads.
- Resistant to wear, aging, rust.
- Good waterproof performance.
- Easy to install.
Waterstop 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.
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.
