Rubber waterstop belts and rubber waterstop sheets are primarily made from natural rubber and various synthetic rubbers, mixed with various additives and fillers. They undergo plasticizing, blending, and molding processes. There are many types and specifications, including bridge type, mountain type, P-type, U-type, Z-type, Y-type, T-type, H-type, E-type, and Q-type. They are produced by blending natural rubber or various synthetic rubbers with multiple additives and fillers, followed by plasticization, blending, calendering, and vulcanization processes. They can also be categorized as buried rubber waterstop belts and back-taped rubber waterstop belts based on their application. These waterstop materials offer good elasticity, wear resistance, aging resistance, and tear resistance, are highly adaptable to deformation, and possess excellent waterproofing properties. Their temperature range for use is -45℃ to +60℃. Rubber waterstop belts should not be used when the temperature exceeds 70℃, or when they are subjected to strong oxidation or erosion by oils and other organic solvents. They are commonly used during the construction of underground exterior walls and backfill strips.
