Basements and cellars are particularly affected by moisture, as these rooms are located below the (damp) ground. The walls draw the groundwater upwards from below. The water is pulled upwards against the force of gravity in the walls of the house, this is the so-called capillary action.
High humidity, i.e. relative humidity of over 60 percent, inevitably leads to musty odors and mold growth. The high humidity is the breeding ground of the mold. Conversely, if the relative humidity remains below 60 percent, the mold has no chance to spread and perishes.
Excessive moisture (above 60 percent relative humidity) will result in the following moisture damage:

To know whether the basement is too damp or not, the relative humidity must be measured using a hygrometer (moisture meter). If the relative humidity is above 60%, quick action should be taken to minimize moisture damage.
Analog (synthetic hair) hygrometers are more accurate and reliable than digital hygrometers. We recommend the Croco hygrometer with precise humidity and temperature display.
In the following video you will learn what to look for in a damp basement:

The ecodry dehumidifiers are in daily use in thousands of Swiss cellars. They protect inventory such as furniture, clothes and equipment from moisture damage. They also prevent musty odors and mold growth on walls. In this way, ecodry actively contributes to the preservation of the building fabric and thus to the maintenance of the property.
