Drying out an old sandstone villa. In February 2013, we installed our Drymat system for Prof. Dr. B. in 01189 Dresden.

The current is fed in via so-called continuous anodes. After just one year, the 60 cm thick sandstone masonry could largely be handed over dry. As a physicist, Prof. Dr. B. is well acquainted with the method. Drymat installed the negative pole (several cathodes) beneath the floor. The waterproofing plane therefore lies under the house - the floor can dry out. In the area of the old chimney, damaging salts once dissolved in the water emerge at the surface, a typical sign of drying out. The drying will continue to progress in future. The system remains in the house as an active barrier against rising damp. Just a few watts (comparable to a doorbell transformer) are enough to keep the building dry in the long term.
