What is rising damp, how do you recognize it? And what can you do about it? Aquaconsult answers all your questions.


What is rising damp?

One of the causes of moisture in the wall is rising damp. At the same time, it is also the most common moisture problem. Rising damp only occurs on the ground floor.

With rising damp, groundwater is the major culprit. Groundwater is absorbed by the walls because there is no water barrier at ground level. The worst moisture spots may be near the ground, but it can always spread further into the wall.

Rising damp is most common in older homes, but new construction houses can also suffer from it. Usually it is because a mistake happened in the construction.


What are the consequences of rising damp?

Rising damp is first and foremost very unhealthy for your home and your walls. It reduces the strength of walls, causing structural damage. The damage is most visible on interior walls: mold, moisture spots, loose plaster, a musty smell.

Structural damage occurs mostly on exterior walls. In freezing weather, the moisture in the wall can freeze, causing cracks in the wall.

In addition, rising moisture creates high humidity, which causes you to need more energy to warm the same room. The more humid the air, the more energy you need. In the worst cases, your energy bill can cost up to 10% more.

Also, rising moisture - like other moisture problems - can cause health problems. High humidity causes frequent colds and, in some cases, can also cause rashes.

In addition to high humidity, mold is also a problem. Mold often causes respiratory and lung problems. Especially in children, the elderly, or people who already have underlying respiratory problems (such as asthma).


What can I do about rising damp?

First and foremost in important to have a specialist in moisture control make the right diagnosis. Because every moisture problem requires a different approach.

With rising damp, that approach is primarily wall injection. In this process, experts drill holes in the damp wall and inject those holes with moisture-resistant gel. That gel then spreads deep into the pores of the wall and, once cured, forms a permanent horizontal barrier.

AquaConsult uses REWAHGEL Inject 3A+ as a moisture resistant gel. This is the highest qualification you can find; therefore, we use only the best quality to help you. REWAHGEL Inject 3A+ is solvent-free, odorless and non-caustic. We can use it without health hazard in inhabited areas and it is non-flammable. This injection gel has been used for many years and has proven its effectiveness several times through tests. It is therefore a result of thorough research.

How do I recognize rising damp?

As mentioned earlier, rising damp only occurs on the ground floor or in the basement. On interior walls, you can recognize rising damp first and foremost by height: do the moisture spots occur mostly close to the ground? Then it is most likely groundwater rising to the top of the walls.

On interior walls, you can recognize rising damp by the following symptoms: discolored plaster, crumbling plaster, white salt circles or stains, wallpaper coming loose, wall finish coming loose or mold. You can also often detect a musty smell if you are in a room with damp walls.

In winter, the moisture in the walls freezes causing the moisture to expand. Thus, in the exterior walls, you can also sometimes notice broken joints. In many cases, the basement is also affected by rising damp. This is because a basement is surrounded by groundwater. But rising damp does not only occur in winter. You can also suffer from rising damp in the summer.

We as experts can use a moisture meter to determine the moisture level at a certain height in the wall. If the moisture is only close to the ground on the ground floor, we are clearly talking about rising damp.


How does AquaConsult proceed?

First of all, one of our field engineers will visit you to make a proper diagnosis. This is very important so we can help you in the best way.

Has rising damp been identified?

Then professionals will come to you to treat the wall. First of all, the affected plaster layers are removed so that we can prepare the wall for the injection of the damp-proofing gel. Once the walls are injected with the gel and the plaster layers are reapplied, you have to count on an 8-12 week drying process before you can decorate the wall again.
