Introduction to the rubber water stop:
Rubber water stop belt uses main raw material of natural rubber and various synthetic rubber , adding various additives and filler, formed by the plastication, mixing, pressing.
The necessity of installing water stop:
In many countries in the design of large scale engineering construction, civil engineering, water and soil structure has a certain scale, and there is waterproof and shockproof requirements, so use and install rubber waterstop is effectively solve various problems encountered in the above.
What kinds of the rubber water stop can be divided into?
It can be divided into four types. They are general rubber water stop, pvc water stop,   water  swelling  rubber water stop and rubber water stop with steel edge.
the scope of application:
Generally used in basement wall and the construction of the late poured band , rubber water stop belt is mainly used for one of the basic engineering cast-in-place concrete when in construction joints and deformation joints and concrete structure , such as underground facilities, tunnels, aqueducts, dams, liquid storage structures and so on.
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.

Can you describe about the application of the rubber water stop?
It is mainly used for underground structures, dams, storage pools, swimming pools, roof and other buildings and structures of the construction joints and deformation joints waterproof.
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.
