Rubber waterstop is a rubber product, mainly used for waterproofing construction joints in engineering buildings. Rubber waterstop is a waterstop product mainly used to be set inside concrete such as concrete deformation joints and expansion joints. It has the ability to adapt to the expansion and contraction deformation of concrete through the elasticity and structural form of rubber materials. The waterstop uses the high elasticity and compression deformation of rubber to produce elastic deformation under various loads, thereby playing a role in tightening and sealing to effectively prevent water leakage and seepage of building components, and plays a role in shock absorption and buffering, which can ensure the service life of engineering buildings
