Rubber waterstop strips are waterproof sealing materials made from rubber, featuring an expansion property when in contact with water, and are extensively used in concrete construction joints, expansion joints, and waterproofing treatments for projects such as civil air defense, subway, tunnels, and sewage treatment plants [1] [3]. The material is categorized into three types: putty-type, product-type, and self-adhesive strips. The putty-type combines elasticity and waterstop expansion functions, adapting to joint deformation; the product-type is pressure-resistant and corrosion-resistant, commonly used in shield tunnel joints and building expansion joints; and the self-adhesive strips achieve direct bonding with concrete through butyl rubber.
