Rubber waterstop is made of natural rubber (NR), chloroprene rubber (CR), nitrile rubber (NBR), etc. It features high elasticity and tensile deformation capacity, and is firmly anchored. It is suitable for concrete structures with small deformation such as construction joints and expansion joints. Among them, the embedded CP/CB type adapts to different expansion requirements through the design of holes in the middle or not; the 651/652 type is a commonly used model, with wedge-shaped protrusions to enhance sealing performance; the back-attached EB/EP type forms a closed waterproof area through the interlocking of teeth with concrete and the filling of grouting pipes. The product has excellent weather resistance, a long service life, and complies with the GB/T18173.2-2014 standard. Customized sizes and corner joints are supported, making it suitable for harsh environments such as underground projects and sewage treatment plants.
