Rubber water-stop belt, uses rubber's characters such as flexible and elastic distortion under pressure, which can prevent to leak water and have the action of damping effectively.
The products are widely used in various types of concrete structures.
For example: dam, reservoir, culverts and tunnels underground works, which can't cast continuously, or because of the deformation of the foundation, or for the reason that temperature changes cause the thermal expansion and contraction of the components of the concrete and other reasons. In the proce s of casting, it often has the Cracks of distortion, the cracks of construction, and the prevention of seepage of these cracks should resort the means which casts the rubber water-stop into the place of the cracks of distortion, it can also prevent the groundwater (or external water) from infiltrating the building structure, and prevent the water of the construction from penetrating into the outside.
Rubber water stop belt utilizes high elasticity and compressibility of rubber to deform its elastomer body under various kinds of loads to fasten and seal, prevent building's leakage and seepage effectively. And it can act as buffer to absorb shock. Because of discontinuous construction and foundation distortion, there have to be some construction gap, subsidence gap and distortion gap etc in many project constructions. Therefore the water stop belt must be applied in these gaps against water leakage problems.
Rubber water stop belt is built in construction gap, subsidence gap and distortion gap during concrete construction of canals, tunnel mouths, dams, cistern and basements.
