Mold on floor
Mold on the wall or ceiling is not new, but quite a few homeowners complain beyond mold under screed, which is considerably more complicated. Under the floor is often floating screed, in which various elements such as the insulation or the floor heating are installed. The insulation is as a rule directly on the concrete floor, while the floor is delimited by the rim of a strip of soft foam. Thus, the sound is not transmitted to the adjacent walls when walking on the floor. Mildew Located under screed, so we need to act quickly, often the problem occurs on already during the construction phase. However, this can be significantly easier to eliminate.

Schimmel under screed - when the soil is particularly vulnerable?

Basically, there are different types of floating floor, such as bitumen, concrete or anhydrite screed. The so-called leveling floors have a very high water content, as they moved in quite a liquid form. In this case, the risk of infestation of mold under screed is particularly high. For comparison: cement screed has a rather high pH and mostly mineral components, so it is hardly susceptible to mold or other bacteria.

Still used for insulation often called polystyrene foam, for impact sound insulation contrast Mineralfassern come mostly used - basically an ideal breeding ground for mold under screed, because they possess exactly the surface texture and chemical factors that under the growth of mold screed favor. Of course, only provided over a longer period, there is enough moisture in the soil.

Schlemiel under screed can be formed even if the moisture in the soil and only lasts several days, because we know that develop mold very quickly. In floating floor is the case that in particular the thermal insulation is infested with the fungus, as they come on the edge joints with the room air in contact. 

Entering the ground, so this will be charged at different locations. This can be the spores from the mold under screed even up "pump" and literally carry through the room, making a spread very likely. Of course

(Water clean up)mold is under screed to this extent a massive risks related to exposure of our health.

The proper emergency measures to prevent mold under screed

Most water seepage is not seep into the substructure of the house, but is still in the layer above. From here it should as soon as possible to be pumped out, so that the area should be thoroughly drained. For the drying, there are various ways in which the adsorption or the condensate drying.

 However, one reduces this only the humidity in the room, and thus accelerates the natural process of drying. This variant takes under the screed, but too long, because in the meantime, back again forming mold because water that has penetrated the insulation, hardly can evaporate. It is not free and has to escape virtually no space at all of the thermal insulation to the outside(Smoke ).

Experts therefore rather prefer the ventilation with dry air cavities in the ground, what happens with the help of negative or positive pressure. Here, the infrared technique is used. When overpressure method is pumped warm air through small holes in the floor in the ground cavities. Thanks to special condenser ambient air is dehumidified effectively. If the insulation is mold, they or their spores are blown into the air, which is particularly risky to health. Therefore: If it is found that mold is under screed in the insulating layer, it works best with the vacuum method.

(Mold)When vacuum process pumping the moist soil air out with the help of vacuum turbines, which also takes place via small holes in the floor. The air is by means of a HEPA filter which filters spores dehumidified. Subsequently, the dry air passes over the edge joints is passed back into the cavities of the insulation layer. 

In this way, the area where was mold under screed, be fully dried without spread the dangerous spores in the air and people can be inhaled by us. This method is extremely effective for removing mold under screed, but also time consuming. If there are sand, slag, clay or Kalksplitt in Konsturktion the floor, you have to take into account a Zeiraum of several months for the drying.
