We can produce various specifications of Rubber waterstop strip according to the customers requirements.

Description of Rubber waterstop strip

Rubber waterstop strip is a kind of water stop of both rubber products characteristics, and the water expansion to the function of water stop on its own. Widely used in civil air defense, such as subway, tunnel, swimming pool, sewage treatment engineering, and other concrete engineering construction joint, expansion joint, crack.

Expansion under the influence of water with the water of water stop expansion properties of water putty and meet Rubber waterstop strip. Encounter water swelling rubber is a kind of new special rubber products. It is a combination of general rubber products performance, and can meet the expansion of the water on its own performance, is a new type of waterproof material, water stop, waterproof effect is more reliable than ordinary rubber.

Specifications of Rubber waterstop strip:

1. The material is rubber
2.expansion rate is fast and water pressure resistance is strong
3.size:10*20mm, 20*30mm, 18*28mm

Application of Rubber waterstop strip:

Rubber waterstop strip is designed for sealing construction joints, cold joints and working joints in concrete, around pipe penetrations, in sewer joints, against slurry walls, sheet piling.

It can be used in combination with infiltrate stop in situation, which is deemed to be high risk.
