Moist walls - find cause & dryFor many homeowners, damp walls and wet basements are a problem.
Above all, the consequences of this damage, because not only the building fabric is severely attacked, but also the health of the people who live in such a house.
There are a number of procedures that can be used to dry out damp walls. But by no means all procedures bring the desired results and not all procedures are suitable in individual cases. Typical methods for draining wet walls are e.g. the wall separation, the injection process or the electrophysical building drying.
Basically, however, the first thing is to identify the causes and then act accordingly. For this reason, always a specialist should be used, who can determine the cause of the moisture damage. Depending on how the damage occurs, special measures are required.
The pleasing thing here: not always extensive remedial measures are necessary. Moist walls can also be found in leaky pipes. It does not always have to be water from outside, which penetrates into the masonry and causes massive damage here. If leaky pipes are the reason, this problem can be solved quickly, inexpensively and nevertheless permanently.
Cause research in damp walls
Specialists, such as construction experts, building biologists or architects are able to find out exactly why there are damp walls in a house.
With special devices, they make measurements and can thus say exactly what water is wet walls.
This, in turn, sheds light on where the water enters the masonry and limits the possibilities that help against the damp walls. Such an expert should always be charged with the cause research, because even a good handyman, it will hardly be possible, the causes of damp walls
to clarify in detail. You can find such a specialist, for example, over the Internet.
Many construction experts are independent and create independent building surveys, which are aimed at the area of damp walls. Even with the TÜV, you can find such a specialist.
The advantage of this is that you not only get expertly informed about what kind of cause it is, but also get tips on possible remedial measures.
Overview of the common methods in the fight against damp walls
A proven method for the renovation of damp walls is the wall separation. Moist walls are prized with a special tool and a geomembrane is inserted. The joints are mortared and moisture no longer has a chance to penetrate the masonry. The disadvantage here is that the stability of the walls can be affected, which is why in this case in each case a specialist is to be consulted.
Another method is the so-called injection method. At small intervals in this case holes are drilled in the wall, in which an impregnating agent is introduced. However, this method is not recommended for all types of damp walls, because the moisture penetration of the wall is more than 50 percent, the pores in the masonry can not absorb anything, including impregnation.
Very controversial is the so-called electrophysical process. This is to be directed by the application of an electric field, the liquid transport in the wall in a different direction. Theoretically, this method works, but consumer centers warn again and again, because there are still many problems in practice that can not be satisfactorily resolved.
The most effective methods include remediation work, where the basement is sealed from the outside. For this purpose, a trench is dug on the masonry and the basement walls are insulated by different materials.
