Rising damp is an issue that has the potential to affect any building. It is a particular problem in older houses where the original rising damp treatment (or damp proof course) has become damaged or where the ground level around a property has been raised with the addition of a new path or drive way.
Over time, water from the ground works its ways through the brick work, stone work or through the softer mortar that holds the brick work together. This ground water often contains soluble salts which are deposited on the surfaces of the walls as they dry out. In turn, these salts draw moisture from the atmosphere giving a permanent damp feeling to the wall and producing one of the key indicators to help identify rising damp.
Practically all buildings are surrounded by natural moisture that is trying to get into the dry structure of the building. Materials such as stone and brick are naturally porous and will soak up moisture like a sponge without the aid of a damp proof membrane. When a building is constructed, a preventative course of rising damp treatment is generally installed in the form of a damp proof course into the walls to prevent rising damp appearing however, when this treatment does not exist or becomes damaged the most common result is rising damp.
Typical signs of rising damp rather than other damp problems are a 'tide line' of yellowish or brownish staining or blown plaster in the lower area of your wall above your skirting board. You also might have damp or rotting skirting boards or flooring. You may see white, fluffy deposits in your plaster - these are 'salts' which the damp has washed out of your bricks and into your plaster. Black spots of mold may also appear on the damp areas of your wall.
This can be done in a number of ways, for example opening windows, turning on extractor fans, using dehumidifiers, drying clothes outside and covering pots and pans whilst cooking. Air conditioning or ventilation systems can be installed that help remove moisture from the air, and move air throughout a building. The amount of water vapors that can be stored in the air can be increased simply by increasing the temperature.
Interstructure condensation may be caused by thermal bridges, insufficient or lacking insulation, damp proofing or insulated glazing.
