But especially with regard to the health of the inhabitants, damp walls are very risky, because they are the ideal breeding ground for mold and fungi.
The damage caused by damp walls is so massive, because it is usually only very late recognized that there is even moisture in the masonry.
In addition, moisture is often underestimated and mistreated. If moisture damage is not properly treated in the walls, the existing insulation becomes damp and loses its function. The result is rising heating costs.
Experts use a variety of methods to permanently dry damp walls. The method to be used always depends on the cause of the damp walls. This requires that in the suspicion of damp walls first a cause research must be operated. For the layman it is not easy to recognize wet walls at first.
It is even more difficult for the layman to find out the causes responsible for the damp walls. Therefore, it is highly recommended to commission an expert with the assessment of the suspicion of damp walls. There are independent surveyors you can contact,
which can be e.g. at the TÜV finds.
Repairs of damp walls are not for the home improvement. Even if he is still so versed and can handle so well with different tools. Without a proper execution of the repair of damp walls, the work is quickly ineffective. Therefore you should dry the damp walls

So you can dry and renovate damp walls
A specialist takes several steps to find the causes of damp walls and eliminate them. As a rule, the craftsman first analyzes the overall situation. That He looks at the building very closely and makes different measurements.
If it is an old building, the causes of damp walls are usually quickly identified. Often, a seal is missing, which is now required by law in new buildings. If it is a new construction, it is most of a defective or incorrectly processed waterproofing that is responsible for damp walls. By analyzing the existing damage, the expert can create a suitable sealing concept.
One of the most commonly used humid wall drainage systems is the installation of a retroactive horizontal barrier. One cause of damp walls may be rising damp. The walls absorb the moisture from the floor and pass it through the entire masonry to below the roof.
This can be counteracted by barrier layers, which are installed horizontally in the masonry. If this is a new building, water-impermeable films are used. In old buildings can be created by a so-called. Injection a moisture barrier.
Here, a special paste is subsequently introduced into the masonry. This prevents moisture from continuing to creep through the walls.
Although this prevents the moisture from rising, the actual cause has not yet been eliminated. Moisture creeps into the masonry due to missing or defective sealing of earth-contacting components.
Thus, a subsequent external sealing of the basement or ground floor must be created. This means that the basement wall must be sealed from the outside. For this purpose, a shaft is excavated around the building and the masonry is re-insulated from the outside. For this purpose, a variety of methods are also available.
