expandable swelling waterproof rubber water stop strip
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.
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.
