Rain penetration into masonry (penetrating damp) can occur in buildings of all ages. At its most obvious, it penetrates right through the wall and is visible as a damp patch on the internal wall – often causing discolouration and peeling / flaking of paintwork or wallpaper. However, rainwater penetration can be damaging to a property, even if it does not penetrate all the way through a wall. For example, moss growth, increased heat loss, and frost damage can be caused by rain penetration into masonry.
Rain penetration is not a problem that is restricted to single-skin walls. Poorly installed wall-ties or cavity wall insulation can provide a pathway for rain penetration to track through cavity walls.
Before any form of dampness in walls can be treated, the source of the damp problem must be correctly identified. In order to find out which type of dampness is affecting masonry, a full examination of the property should be undertaken.
