Product Information

Back-mounted rubber waterproof belt is also called back-mounted waterproof belt or external waterproof belt. It is a kind of waterproof structure which is set on the outside of concrete deformation joint and settlement joint wall board (water-front surface) of underground structure. It has the ability to adapt to concrete expansion deformation by the material elasticity and structural form of water-proof belt. Back-mounted rubber water stop is mainly made of natural rubber and various synthetic rubber as the main raw materials, mixed with various auxiliaries and fillers, after plastic refining, mixing, pressing molding, its variety specifications are more, there are bridge type, mountain type, P type, U type, Z type, B, T type, H type, E type, Q type and so on. The back-mounted rubber water-stop belt can be classified into the middle-buried rubber water-stop belt and the back-mounted rubber water-stop belt according to the service conditions.

Back-mounted rubber waterproof belt is the use of rubber high elasticity, elastic deformation under a variety of loads, thus playing a solid seal, effectively prevent leakage of building structures, water seepage and play a role in shock absorption and cushioning. In the design of many engineering buildings, there are certain expansion and contraction requirements between civil engineering and water and soil structures, and there are some problems such as waterproof and earthquake proof. Therefore, the use and installation of rubber water-proof belt is an effective means to solve the above problems.

Product Uses

It is mainly used for the foundation engineering, underground facilities, tunnel culverts, water conveyance aqueducts, water retaining dams, etc. which are set in the construction joints and deformation joints when the concrete is cast in place and become an integral part of the concrete structure to ensure the service life of the project construction.
