Product Details

Expandable swelling Rubber water stop

Application

Rubber water stop mainly used in Concrete cast-in-situ located within a construction joint and deformation joint with concrete structure

is one of the basic engineering,such as underground installation,Tunnels culvert,The water

conveyance aqueduct,Dam, liquid structures and so on.

Advantage:

1.Material:Rubber

2.Applicable for various joints during construction and use

3.Provide a wide range of product specifications

4.According to the design and construction requirements

5.Reasonable price

The main characteristic is that the Waterproof inside is made of Special rubber water

swelling.and when the rubber water stop meet the water and then swelling,the tightness of

rubber water stop and the structures will be increased,the effect of waterproof will

be better.
