What is Rising Damp?
Rising damp or salt damp is a common type of dampness that you can see in buildings. As such, damp issues cause severe damage to a property, you should treat the damp immediately to protect your building from further damage. Rising damp occurs when water from the ground rises up through the brick and mortar of a building through a process widely known as “capillarity.” The water rises up the wall of a building in the same way oil rises up through the wick of a lamp. The height to which the water will rise depends upon different factors such as poor structure of the bricks and mortar, rate of evaporation, etc. Masonry has a high proportion of fine pores as compared to coarse pored material.
Ground water & Hygroscopic Salts
Ground water used to have soluble salts, including chlorides, nitrates, and sulphates. When rising damp issue occurs, these salts pass with the water up the wall and are left behind when the water evaporates. Over many years of active rising damp, large quantities accumulate within the masonry and decorative surface, and become concentrated in a general ‘salt band’ toward the maximum height of rise. Both chlorides and nitrates are generally hygroscopic, which means they can absorb moisture from the surrounding environment.
The Best Way to Deal with Rising Damp
Damp treatment largely depends on the type of damp that is affecting your home. You may find more than one kind of damp which can make the solution more complicated. In any case, you will need to consult a specialist damp company to examine the issue, and treat accordingly.

Cold spots on wall increase condensation, therefore, making sure you have better insulation. By having a cavity wall insulation or specialist insulation materials fixed to the outside of your home can prevent rising damp.
To deal with rising damp, you need to make it sure that your damp-proof coursing is working well. If you have a good damp-proof course, you can solve the issue simply by digging away the soil on the exterior side to the damp wall to below the level of the damp proof course. In case, the damp-proof course is not working well, you should replace that with new good one.
