Rising dampness is a term that no one wants to hear about a house, whether they are a homeowner or a potential homebuyer. Even though such a form of damp is uncommon, it can be expensive to repair.
When water infiltrates a brick base and damages the walls, it is known as rising damp. This is not an issue that a homeowner should overlook—and not only because it can affect the value of the house. This can make a room feel cold, unpleasant, and unsafe, and it can cause structural or weatherproofing problems in the worst-case scenario. Fortunately, dampness can also be handled and avoided without the need for a specialist.
There are also simple signs to look for that might signify a problem, as well as simple steps you can do to prevent it from occurring. Rising damp is a rare but severe form of damp that damages building walls.
Moisture from the surface rises through the walls as a result of capillary forces. This indicates that like a collection of straws, groundwater is drawn up through small holes in the bricks.
This liquid carries salts, which can move up the wall as well. Other porous structural elements, such as plaster and the wood used in baseboards, joists, and skirtings, are found around the affected wall. These products can also readily absorb groundwater, and you can see signs of wet rot in the wood. Paint and plaster deteriorate with time, and wallpaper loosens. At the point where the surface water has hit, a noticeable stain emerges on the wall in the shape of a tide mark.
Salts can emerge on the inner wall as well. This is a common symptom of rising damp and can result in paint and plasterwork debonding. Mortar can collapse externally, leaving white salt stains on the wall. Buildings can face massive structural damage as a result of rising damp.
