A common enquiry we get almost every week from our customers when carrying out damp proofing surveys is; ‘how come the wall is damp seeing as its not an external wall?

To start with we need to understand the principles of how rising damp affects walls within a property, rising damp can be simply explained as water (ground water) rising up slowly through lower sections of porous walls whether made from brick or stone, the water originates from the ground and rises up the wall of a building in the same way that a paper towel will soak up surrounding water, genuine rising damp can only affect walls built on to a foundation, walls within older properties tend to have solid brick/stone built internal walls (walls sectioning off different rooms) that are built onto a foundation in the ground and therefore ground water has the ability to rise up these walls if an effective damp proof course is not present.

Modern properties tend to have internal walls built from wood and plasterboard often referred to as ‘stud’ walls, these are simply walls made from wooden joists to form a frame and plaster board added to them, these walls sit on the floor of the room whether its a concrete floor or floorboards and do not have any contact with the ground underneath so do not suffer from true rising dampness.
