Description of rubber waterstop belt:
Rubber waterstop belt 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 andother water retaining or excluding applications with high movements or water pressure.
Materials properties of rubber waterstop belt:
SBR and neoprene rubber, as the most common materials for rubber waterstop belt manufacturing, are used extensively in United States and the worlds. The SBR water stop is preferred for water containment, while neoprene rubber waterstops belt are recommend for applications of sewage disposal or chemical industries. As your request, natural rubber, EPDM, Nitrile and Silicone waterstops are also available.

Applications of rubber waterstop belt:
1.Ideal for high movements joints.
2.Water containments.
3.Water excluding.
4.Tunnels and civil engineering structures.
5.Water and waste treatments.
6.Dams, reservoirs, and spillway.
7.Chemical areas.
8.Irrigation canals, sea walls and culverts.
Main types:
1.Dumb bell type rubber waterstop belt, with flat web section, are ideal for construction and partial contraction joints with little or no movements.
2.Center bulb type waterstop belt, 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.
Installation:
All the rubber waterstops belt are designed to cast in the concrete as an integral joint sealing system. Pre-fabricated waterstops are also supplied to reduce site jointing.
