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. Four different types of rubber waterstops: three center bulb type and one dumbbell type. RW-01: Rubber waterstops are most widely used type for concrete constructions. 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. 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. 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. A piece of center bulb type rubber waterstop on gray background. RW-02: Center bulb type rubber waterstop.

RW-04: Rubber waterstop - dumbbell type. Plan drawing of four center bulb types of rubber waterstops in different length RW-05: Rubber waterstop – center bulb type. 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.
