If walls of the basement are not directly arrivible there a chance to seal the wall from the inside. By this way the rooms and walls can be saved for moisture, but not the core of the wall.

To stop the capillary rise it is necessary to use a horizontal barrier.

By this internal waterproofing I remove old pflaster and colour, then I apply sealing compounds in several layers. After this I do a salt treatment, bond and key coat and finally a breathable pflaster.

Restoration plasters are very important; they enable the wall to dry out.
