Introduction to the rubber water stop:
rubber waterstop is of high quality natural rubber and various synthetic rubber as the main rawmaterial, adding all kinds of promoter and filling agent, mixing, sulfide, classics plasticate, moulding and made a waterstop product, it is using high elasticity of rubber, produce elastic deformation under various pressure load, thus have strong sealing, can effectively prevent the leakage of building structure, water seepage and shock absorption effect.
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's the commonly used width and thickness of the rubber water stop?
Commonly used width (mm):230,250,270,280,290,395,300,350,400 and so on. Special specifications can be customized. Common thickness (mm):6,7,8,10mm 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.
Construction and installation:
The waterstop is part or all buried in concrete pouring in pouring process of concrete pouring , concrete has many sharp stones and sharp steel head, due to the ratio of tensile strength are lower 3-5 times than tear strength of that , waterstop will be enlarged without external force gap once punctured or torn , so in the process of waterstop belt positioning and concrete pounding, attention should be paid to positioning method and pouring tamping pressure, so as not to stop punctured hose, sealing effect, with specific attention to the following items:   1 waterstop shall not be outdoor exposure for long time , to prevent rain, do not contact with the chemical substances that is strong. 2 prevent the machinery and steel bars damage the waterstop in the course of transportation and construction. 3 during the construction, water stop belt must be fixed reliable to avoid displacement occurred in the pouring of concrete , ensure the waterstop in the correct position in concrete . 4 fixed sealing strip method: using additional reinforcement fixation; special fixture fixation; the wire and template fixed, for perforation, can only choose install area at the edge of the waterstop shall not damage other parts. 5 users should be according to the engineering structure when orders, calculate the length of good products when design drawings, different-shaped structure must have drawing instructions and try to let the seal belt are connected into a whole in the factory, you can adopt the method such as the electric heating plate vulcanization adhesion or cold bonding (rubber water stop belt) or welding (of the plastic waterstop) method if need connect in site .
