The middle buried rubber waterstop belt, which is mainly used to stop the water -stop product set inside the concrete such as concrete deformation joints and telescopic joints. It has the ability to adapt to the elasticity of rubber material and structure to adapt to concrete telescopic deformation. This product uses the high elasticity and compression deformation of rubber to generate elastic deformation under various loads, thereby tightening and sealing and effectively preventing the water leakage, water seepage, and shock absorption and buffering, which can ensure engineering construction Life life of things.
