Double ball rubber water stop

Rubber waterstops are divided into two-ball and three-ball types, subdivided into width and thickness (reinforced type)
Material: natural or synthetic rubber


The rubber waterstop is made of natural rubber as the main raw material, mixed with various additives and fillers, and is formed by plasticization, mixing, and pressing. It is mainly used to be set in construction joints or expansion joints during concrete pouring, so that the concrete poured in the previous and next stages can be integrated. Reliable fixing measures must be taken for the rubber waterstop. When tying steel bars and supporting formwork, it is necessary to prevent displacement during concrete pouring and ensure the correct position of the waterstop in the concrete.


  • The rubber water stop is manufactured based on the "in" size as the production unit, and the "mm" in the table is an auxiliary indication.
  • If the demand is for non-standard products, the size standard can be provided and can be customized separately.
