The dampness from capillary rise occurs with efflorescence of saltpetre (white streaks) and occurs primarily in masonry or full brick walls in contact with the ground.

The structure in direct and constant contact with the ground picks up water in the soil through the foundation structures.

Because of the phenomenon of capillary rise, water penetrates constantly into the elevation structures with a path that proceeds from the bottom upwards.

Restoration of damp walls should always be faced in respect of the physics of construction.

Therefore the restoration operation faces the problem at three levels:

1. reduction of the quantity of water enticed by foundations or underground walls;

2. elimination or reduction of the water flow that rises into the wall;

3. increase of water evaporation from the walls towards outside.

The injection techniques by absorption or by DRYsec/DRYflex fogging, combined with restoration plasters WTA with thermal insulation are the most effective.
