What is rising or
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 big culprit. The gRound water is absorbed by the foundation and walls, so the worst dampness is near the ground, but it can always spread further into the wall. Both internal and external walls can be severely damaged as a result.

What causes rising damp?

Rising damp is most common in older houses, but it can also affect newly built houses. This is usually because a fault has happened in the building structure (and usually the foundation) . In both cases, we are usually talking about houses that have problems with the water barrier.

A dam is the waterproof protective layer that prevents groundwater from penetrating the walls. If this water barrier at ground level is missing or damaged, the walls will absorb groundwater like a sponge. The capillary action of the walls ensures that the moisture is transported upwards. This causes you to suffer from rising damp.

What are the consequences of rising damp?

Rising or rising damp is associated with numerous negative consequences. First and foremost, it is 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. Think of fungi, discolouration, damp patches, loose plaster and a musty smell.
  • Structural damage mainly occurs 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 means you need more energy to heat up 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 damp - 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, high fungi a problem. Fungi often cause respiratory and pulmonary problems. Especially in children, the elderly, or people who already have underlying respiratory problems (such as asthma).

How do I recognise rising damp?

Rising damp always expresses itself just above the surface level. As a result, rising damp only occurs on the ground floor or in the basement.

On internal walls, you can recognise rising damp first of all by height: do the moisture spots occur mainly close to the ground? Then it is most likely groundwater rising to the top of the walls.

On interior walls, you can recognise rising damp by the following symptoms:

  • Discoloured plaster,
  • Crumbling plasterwork,
  • White salt circles or spots,
  • Loose wallpaper,
  • Finishing wall coming loose,
  • Mould,
  • Or a musty smell.

In winter, the moisture in the walls freezes, causing the moisture to expand. So in the exterior walls, you may 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 this moisture problem in summer.

We, as experts, can work with a moisture meter determine the moisture level is 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.

What can I do about rising damp?

First and foremost, it is important to getting a specialist in moisture control to make the right diagnosis. Because every moisture problem requires a different approach, and only with a correct diagnosis can correct action be taken.

In the case of rising damp, the most appropriate approach is the injecting walls against moisture.

  • This involves experts drilling holes in the damp wall and injecting those holes with damp-proof gel.
  • That gel then spreads deep into the pores of the wall and forms a permanent horizontal barrier after curing.
