Control and seal cracks, increasing the productivity of the castings

BREAK is a self-sealing watertight box element designed to control and seal any spontaneous cracks that develop in the reinforced concrete. They seal automatically when water passes through, thanks to the hydro-expansive action of the bentonite joint installed inside.

Where to use it

    To determine and guide contraction phenomena in reinforced concrete walls, constructed continuously, such as:
  • Retaining walls in general
  • Tanks
  • Waste water treatment plants
  • Supporting walls, etc


  • Perfect hydraulic water-tightness
  • Maximum control of shrinkage of reinforced concrete
  • Possibility of preparing continuous concrete castings without joints
  • Considerable savings in terms of time and money
  • Allows the reinforcement bars to be laid without interruptions
