Jingtong Rubber Water Stop with Center Bulb Buried Waterstop

Product Description

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.

Features & benefits

*High elasticity. 

*High elongation.

*Excellent high movement accommodation.

*Capable to withstand high hydrostatic head.

*Adjust for subsidence and seismic movements.

*Hot vulcanized site joints.

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.

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.
