A solid two-family house with natural-stone masonry.

The L. family from Mulda owns a well-maintained two-family house with natural-stone walls over 50 cm thick. The plinth area in particular showed clear signs of moisture – a typical damage pattern in older, solidly built buildings without a functioning horizontal damp-proof course.

Our solution:
To dehumidify the masonry, we installed our proven Drymat system. Specially configured varistor anodes were used, which deliver a precisely defined amount of current evenly into the masonry. This so-called "active electrophysical barrier" ensures a controlled reversal of the moisture movement within the wall cross-section.

Efficient and economical:
The power consumption for drying and keeping the walls dry is under €10 per year.

A major advantage of our system:
The waterproofing level is not determined by external coincidences or the nature of the wall, but specifically by the position of the cathodes – it lies beneath the building and thus protects against capillary rising moisture.
