Our expert on VTM: this is how we tackle rising damp

Nice news! Recently, our moisture expert Jeffrey Cleners was featured in the VTM programme Can I also. In the episode, he talked about rising damp, a common problem. This problem can not only cause damage to your home, but also has adverse effects on your health. That is why it is important to intervene.

In the broadcast, we explain our approach step by step.

How do you recognise rising damp?

Before tackling the moisture problem, it is essential to be sure it is about rising damp goes. Indeed, each type of moisture problem requires its own specific moisture solution.

Damp rising damp manifests itself in most cases just above ground level and occurs only on the ground floor or in the basement. You will see the moisture spots thus mainly found low to the floor.

The most common signals are:

  • White spots or salt circles on the wall
  • Discoloured or flaking plaster and peeling paint or wallpaper
  • Mould on the wall
  • A musty smell in the room

Rising damp is a problem that occurs in both winter and summer. In winter, frozen moisture expands, which can lead to broken joints in exterior walls.

You let the diagnosis best performed by an experienced field engineer. Who has the right knowledge and measuring equipment to correctly identify the problem and avoid confusion with other moisture problems.

Get rid of rising damp permanently with wall injections

Once a field engineer has determined that the moisture problem is indeed rising damp, he or she will advise to wall injections perform with a special gel. In Can I also let our moisture expert show you how we work.

  1. Preparing the wall for injections. First, the wall is prepared for injections. Here, plasterers repair all cracks in the damp wall.
  2. Drill holes. A hole is drilled into the wall every 10 cm, with a depth just a little less than the thickness of the wall. It is important to do this in the joint.
  3. Inject: Using a syringe, a thick gel is injected under pressure into the wall. This gel then evaporates slowly, forming a new water barrier that prevents moisture from migrating further upwards.
  4. Applying salt membrane. In some cases, it is necessary to install a special membrane that prevents salts from rising to the surface again. This is glued to the treated wall.
  5. New plastering: Once the treatment is completed and the wall is sufficiently dry, new plastering can be applied.

Wall injections are effective against rising damp, provided the wall is in good condition. Severe damage or deeply penetrated salts may require additional measures, such as installing a additional flood defence or replacing parts of the wall.

Treating rising damp permanently

The example presented by AquaConsult in Can I Do It Too? demonstrates that rising damp can be a major problem for homes, but that with the right approach, it can be easily remedied. The method of injecting with gel offers a relatively simple and effective solution, but is best carried out by professionals. By combining this technique with a salt membrane and new plastering, the wall can be restored to its optimum condition.
