What are the most common causes of damp problems in walls?

Rising damp

Rising damp is normally identified when there are high damp readings, or water marks, on the bottom of the walls at ground level. Raising damp is categorised as groundwater that makes its way up through the foundation, the basement, crawl space or the underside of porous outer walls. The damp pulls up through the wall, making your internal walls wet. If you have a good damp proof course in the wall of your home, rising damp will ultimately be stopped, however, older homes may not have a damp proof course and therefore suffer from rising damp.

Penetrating damp

Penetrating damp can be a cause of damp in your walls. This mainly concerns affected exterior facades that rainwater seeps into. Damaged outer walls can allow damp through, and this, in turn, will also penetrate the inner walls. Penetrating damp tends to cause the same symptoms as rising damp. A solution for this type of damp problem is repairing the outside wall and having it waterproofed, however the damp in your interior walls will still be wet, this can be remedied by the SmartDry DryBrick System. Not only will the DryBricks solve the damp issues, but it will also prevent a damp inner wall in the future.


Condensation becomes a problem if the humidity in the house is too high and the moisture does not get a chance to leave the home. Living moisture in the house is completely normal. This already occurs when people are present in the house through breathing. There is also showering and cooking in the house. This can temporarily cause a high humidity in the house. In many cases it helps to open a window. But this does not always help. In cases where a home is very well insulated or if good ventilation is lacking, the home cannot moisture out and no fresh air will enter the home. Condensation will then form. This can often be recognized by the misted windows. But condensation can also settle on the walls. If the humidity in the home is constantly too high, this will affect the walls.

Cold bridges

A cold bridge is normally the result of an insulation issue, whereas the insulation shell of the home is interrupted in one or more places. This can be the case, for example, if cavity wall insulation has subsided. Building rubble can also be the underlying cause of a cold bridge. A cold bridge occurs when a space in the wall forms a cold section between the inner and outer walls-these then become cold spots in the wall. Because damp attracts to the coldest place, cold bridges always pose a risk of damp.
