It is a small box generating low frequency magnetic pulses and it is connected to the 220 volt circuit. The magnetic pulses disorder the structure of the watermolecule, the angle between the hydrogen and the oxygen atoms changes, which changes the dipolarity of the watermolecule and now the water is drawn by the negative loaded earth. After 12 to 18 months the walls and foundation are dry and while the system keeps on working it prevents damp from starting to rise again.

Cappillarity as well as other natural processes cause water in masonry to rise up to considerable height. With the water, salt und pollutans permeating the walls. Now the Drymat® System comes into operation, mainly fighting against damp and saltpeter.
