proPERLA® DPC (Damp Proof Course) stops the disintegration of plaster and paint, the dissolving of wallpaper or the deterioration of the interior paints due to salt efflorescence.

The treated surface can be re-plastered . After a curing period of 7 days, the damp proof course will have its full performance. The water absorption is reduced by more than 95%.proPERLA® DPC successfully passed various analyzes and fulfills the requirements of WTA and CSTC. It has been classified as a treatment with an excellent performance for masonry works.

Damp walls cause growth of mold

A wet core insulation loses its effective insulating properties and is no longer able to keep walls dry. This can cause considerable risks to human health and pets.


The treated surface remains breathable. Moisture and air pass easily through the walls from inside to the outside. This results in a significant improvement of its insulating properties. 

Damp walls reduce the building's capacity to retain heat.

A damp wall is not able to stay dry and loses its insulating properties. Just 5% moisture in a wall reduces the thermal resistance by up to 50%.
