Damp Proof Course

The ultimate protection against rising damp

Ultimate damp proof course for the permanent renovation of walls with rising damp problems. The optimal solution for all properties with deficient or non-existent horizontal barriers. The installation of a damp proof course with proPERLA® DPC eliminates long-term moisture problems due to rising damp. The system penetrates deep into mineral building materials. After the treatment, the wall is impermeable to water but remains fully breathable. Expensive mortars are no longer required. Improve the aspect and performance of your walls.

Stop rising damp with a damp proof course

proPERLA® DPC 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%.

• Improves thermal efficiency of masonry by keeping it dry
• Maintains thermal properties of cavity wall insulation
• Reduces heat loss
• Offers a self-cleaning surface
• Maintains the original masonry finish
• Slow ageing or breakdown of the surface
• Will allow the building to breathe
• Clear insulation barrier for +20 years

Proven performance

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.

Breathable

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. A content of only 5% moisture in wall insulation or other building materials reduces the thermal resistance by up to 50%.
