Back-attached rubber waterstop, also known as external-attached waterstop or external waterstop, is a water-stop structure installed on the outside (facing surface) of the concrete deformation joints and settlement joints of underground buildings. It has the ability to adapt to the expansion and contraction deformation of concrete through the material elasticity and structural form of the waterstop.
The high elasticity of rubber is used to produce elastic deformation under various loads, thereby forming a strong seal, effectively preventing leakage and water seepage in the building structure and acting as a shock absorber. In many engineering and building designs, there are certain expansion and contraction requirements between civil engineering and water and soil structures, and there are problems such as waterproofing and earthquake resistance. Therefore, the use and installation of rubber waterstops is an effective way to solve the above problems.
This product is mainly used in foundation projects, underground facilities, tunnel culverts, water aqueducts, retaining dams, etc. that are installed in construction joints and deformation joints when concrete is cast in place and integrated with the concrete structure to ensure the service life of the project construction. When installing the rubber waterstop, if it is found that part or all of the concrete is buried in the concrete during the pouring process, and there are many sharp stones and sharp steel heads in the concrete, the tear strength of plastic and rubber is lower than the tensile strength. 3-5 times. Once the waterstop is punctured or torn, the crack will expand without a lot of external force. Therefore, during the positioning of the waterstop and the pouring of concrete, attention should be paid to the positioning method and pouring pressure to avoid The waterstop was punctured.
