Damp walls undermine your home and your quality of life


The problem and the consequences


Older homes are often damp because they lack proper repellent barriers that keep humidity from seeping into the walls. As well as causing damage to your home, this will affect the well-being of you and your family.

How do walls get damp?
The main process by which humidity saturates the walls is known, in physics, as capillary draw. Water molecules found in the capillaries of building material normally have a positive charge whereas solids, such as walls, are negatively charged. The difference between these two charges, as well as the absorbent capacity of the building material and certain chemical processes cause the water to rise in the capillaries and infiltrate the material.


The consequences of damp walls:


  • Your home loses value year by year
  • High levels of humidity put a strain on your home environment
  • Rot, moulds and fungi hazardous to your health develop
  • Mouldy odours become noticeable
  • Heating costs rise substantially
  • The water in the capillaries carries mineral salts. These are deposited and crystallize with explosive pressure that can seriously damage the wall. Plasterwork, wallpaper and paintwork burst and peel.
