Rubber Water Stoppe

Four different types of rubber waterstopper: three center bulb type and one dumbbell type.
Rubber waterstoppers are most widely used type for concrete constructions.Rubber waterstopper, 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 waterstopper 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.
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 waterstopper, 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.
