Basement moisture is a widespread phenomenon. The underground location does not always make the transition between cool and humid. In the normal range, the cellar moisture is easily regulated by simple means. The air is the best helper.
Ventilation and air exchange cause completely different effects in the cellar than in above-ground living rooms. A central point is the humidity, which changes its behavior by the cooling effect of the soil.
Warm air is able to absorb and bind much more moisture than cold air. If there is high humidity in summer hot air and it cools down, excess moisture settles on walls and floors. The resulting condensation can be produced in large quantities.
Use air temperature properties
When warm air flows into the basement, it cools down relatively quickly and condenses. This leads to cellar moisture, which settles next to walls and floor on everything that is stored in the basement. Textiles become clammy and water-sensitive packaging for example of food softens.
Permanent ventilation is not recommended in the basement at any time of the year. In summer, the condensation is created by cooling. In winter, the cellar dries up, but plumbing can not stand the cold. To use the normal humidity difference to dry the basement, a well-thought-out approach.
- Close doors, windows and other air supply and heat the basement room vigorously. If there is no radiator, a fan heater will help.
- If the air is warmed up so that it exceeds the outside temperature, use the moisture transport of the air. Open all windows, doors and air outlets to the outside.
- After the heated air has leaked, close the basement rooms again. Repeat the process.
- After three to five passes, you have reduced the cellar humidity to a minimum.
