Description of rubber water stop

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 water stops 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.

When as

users'requirements to check mildew test

according to the circumstances, the

mildew proof property must be equal to

or over Grade 2.

Features of rubber water stop

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 of rubber water stop

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.

Types of rubber water stop

1 - Common Rubber Waterstop

2 - Swellable Rubber Waterstops/Hydrophilic Rubber Waterstop belt

3 - Rubber Waterstop with Steel Side

Shapes of rubber water stop

1 - Rubber water stop - dumbbell type

Dumbbell type water stops, with flat web section, are ideal for construction and

partial contraction joints with little or no movements.

2 - Rubber water stop - center bulb type

Center bulb type water stop, 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.

Installation of rubber water stop

Most popular way of the placement of the water stop seal is tied to the steel

frame works or small eyelet by means of small wires, certain metal clamps

made to grip the water stop seal to keep it in proper position.

Our water stops

are profiles based on specially formulated plasticized PVC compound, which

are designed to meet specific requirement of building industry.

It is essential

that a device is used against potential risk of discomfiture that tends to be

caused in concrete structure following climatic, geo-disturbances and frictional

impasse which result in expansion or contraction in concrete structure.

And the

expansion or contraction results in leakage/seepage of water exposing the

structure to bring the risk of cracks or dismemberment

In 2010, the total output of rubber stops in China was 342 million square meters, a year-on-year increase of 15.23%, according to the shanpu consulting industry analysts.

In 2011, the total output of rubber stops was 408 million square meters, a year-on-year increase of 19.30%.

In 2012, the total output of rubber stops was 456 million square meters, an increase of 11.76 percent year-on-year.

In 2013, the total output of rubber stops was 562 million square meters, an increase of 23.24 percent year on year.
