Penetrating damp, sometimes known as moisture ingress, penetrates horizontally through the wall fabric, and is an issue that can affect all buildings with absorbent walls. When it rains, moisture soaks into solid brick/stone walls, but does not usually reach the inner surface due to natural evaporation. However, where an abnormal amount of additional moisture has accumulated and building fabric is absorbent, or defects are present, the evaporation rate will be insufficient to prevent water penetrating right through to the inner surface. This results in penetrating damp.
Penetrating damp can be damaging to a property even if it does not penetrate all the way through a wall. It can lead to other damp issues such as wet and dry rot, damp plasterwork, increased heat loss, damp musty smells, frost damage to masonry and unsightly water damage on both the outside and inside of a property.
