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.

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.

9 - Adhesion of rubber to metal With contact section in elastomer

10 - Notes (1) Adhesion of rubber to metalis used

to the rubber water stop with steel edge.

(2) If there are other special requirements, it could add inspection items properly

after making deal by both sides.

When as

users'requirements to check mildew test

according to the circumstances, the

mildew proof property must be equal to

or over Grade

On-site inspection: 1 - The position of the embedded rubber stop water belt and the pressure of stubble force.

Due to the limitation of site construction conditions, a ship people speaking joint parts of the waterproof power is less than normal parts, so this check the hose connector, should try to avoid the drainage area, the slope is small and easy to form wall water best stay in hong line up and down.

Second check up and down pressure of the joint direction, the direction should be the right direction for irfpa catchment is smooth, the water, the upper water stop close to the surrounding rock and the bottom water stop near the tunnel lining "2 - Buried in rubber water-stop joint strength.

Site construction tend to ignore the flush of joint surface and matting and low welding or bonding strength through joint is close-grained, water proofing property is poor: check the apricot.

With handle gently tore joint, joint strength and surface order situation, MAO is not qualified to adhesive.
