How to Deal With Rising Damp on Internal Walls

The presence of rising damp on internal walls is a serious problem that affects both the internal plaster and the structure of a building. The underlying cause is the moisture from groundwater. These water evaporations contain dissolved salts that are invisible to the naked eye. The resulting crust forms on the walls and absorbs the moisture from the air. The deposits are not harmful to the structure, but they can lead to the development of mould.
