The middle buried rubber waterstop takes advantage of the rubber's high elasticity and compression deformability to produce elastic deformation under various loads, so as to play a firm seal, prevent water leakage, water seepage and shock absorption and buffering effect of the building structure. In the architectural design of general large projects, construction joints, settlement joints and deformation joints need to be reserved due to the failure of continuous casting, the deformation of foundation or the thermal expansion and contraction of concrete components caused by temperature change. Water stop belt must be installed at these joints to prevent water leakage, which can prevent groundwater (or external water) from leaking into the building structure and prevent it from leaking Stop water leakage from the building to the outside.////
