IdroStop PVC BI/BE
Compare variants


  • Waterstops are used to make water-tight structural joints in underground reinforced concrete constructions to avoid ingress from the water table and in reinforced concrete structures used to contain water, such as swimming pools, water tanks and dams.
  • Used within concrete structures exposed to temperatures from -30 to + 70°C.


A highly flexible waterstop made from high-quality thermo-plastic vinyl resins, which form a product with good resistance to mechanical stresses, the aggressive action of chemical products in alkaline environments, sea-water and acids.

Features and benefits:

  • Highly resistant to perishing caused by sunlight, ozone and other aggressive agents present in the atmosphere and water table.

The dimensions and type of Idrostop PVC used for each application generally depends on the following parameters:

  • Type of structure (for both types of Idrostop PVC).
  • Amount and type of movement predicted (no movement, axial movement, a combination of axial and transversal movements etc).
  • Thickness of the cast concrete (only valid for Idrostop PVC BI).
