Rubber waterstop strips are waterproof sealing materials made from rubber base material, featuring the characteristic of expansion when in contact with water. They are widely used in concrete construction joints and expansion joints for projects such as civil defense, subway, tunnels, and wastewater treatment [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 function, adapting to joint deformation; the product type is pressure-resistant and corrosion-resistant, commonly used in shield joints and building deformation joints; and the self-adhesive strips achieve direct bonding with concrete through butyl rubber.
