Dampness recovery system

Dampness recovery and energetic efficiency upgrading of old buildings.


  • Plaster
  • Cement
  • Brick
  • Stone


  • Thermal insulation
  • Acoustic insulation
  • Energetic renovation
  • Dampness recovery

This system provides the dehumidification and the restoration of walls affected by rising dampness through the use of WATstop, an anti-salt barrier; Diathonite Evolution, macro-porous thermal and acoustic plaster; Argacem HP, finishing breathable smoother; D20, water based primer; Plasterpaint Colored, breathable and water repellent colored finishing.

WATstop salt barrier will stop the emission of salts present in the dampness, which will remain down in the brickwork lower part. On the countrary, dampness will be absorbed by Diathonite layer, that will release it externally in form of water vapour, thanks to its high features of breathability and dehumidification.

This is the only system able to combine in just one intervention dehumidifying and recovering features, high thermal insulation capacities and excellent sound absorbing characteristics, realising a real system of building recovery and thermal insulation. Consequently, the system ensures consistency and continuity of thermal insulation feature, because the dampness will be continuously released externally, and the insulating layer keeps to be always dry.

The system can be also used on the internal side of the perimetral walls, in this case it must be applied the smoother Argacem Neutro in spite of Argacem HP, this because it produces a thinner finishing. On Argacem Neutro layer it is then possible to apply a water-based paint for interiors, tiles or some kind of decorative coating .

Key benefits

  • A wall both thermal and dehumidifying: the systems cuts down costs because it is able to solve, in just one work, any problem related to dampness and thermal insulation.
  • High dehumidifying and hygrometric features: the system is able to absorb and release up to 1,0 l/m² of water, and thanks to its high breathability, it allows to re-balance the humidity equilibrum inside the rooms.
  • It does not need high levels of thickness: the system adapt itself perfectly to the surface to be treated, even if unleveled or irregular, avoiding the formation of air spaces and thus reducing the thickness required.
  • System both for inside and outside: the system can be also appied ininternal areas
