When moisture from the outside, it is more expensive
Penetrates the moisture from the outside into the basement is often a more serious underlying problem. If, for example layers of water in the area of the basement collects, it can - in different permeable layers of soil - are the so-called trough effect. The water collects in such a "tub" and pushes from below or from the side in the basement.
In case of missing or overburdened drainage or high groundwater levels water can also have the shafts of light penetrate the basement windows. This can for instance be the case if the slope of land or seepage collects the drains can not cope with particularly intense rainfall. Experts from TÜV Süd recommend waiting drains every ten years by a specialist and rinse to leave, so they make permanent their services optimally.
