Rubber waterstop is manufactured from natural rubber and synthetic rubbers with many additives and fillers by the processes of plastication, mixing and compression molding. It can be used in various concrete joints to prevent water leakage and permeation. It has excellent elasticity and it is highly resistant to abrasion, corrosion, aging and tearing. It can adapt to deformation very well and it is resistant to water. It is suitable for the temperature range of -45 °C to +60 °C. Rubber waterstop cannot be used when the temperature exceeds +70 °C and in the conditions where rubber waterstop is oxidized or corroded seriously by organic solvents.

Rubber waterstops, also called rubber water stops, can be divided into many kinds according to materials, such as natural rubber waterstop, neoprene waterstop, nitrile rubber waterstop and EPDM waterstop. Rubber waterstops of different materials are suitable for different conditions. And we can manufacture rubber waterstops according to customers' requirements. They are widely used for various concrete structures, such as bridges, dams, tunnels, culverts, storage tanks and waste water treatment plants.

We can manufacture rubber waterstops in many shapes, such as ribbed with center bulb, dumbbell with center bulb, ribbed, dumbbell, base seal, tear web, split dumbbell and split ribbed. And we can also manufacture other types rubber waterstops according to customers' requirements.
