What is Rising Damp?
What Causes Rising Damp?
This most commonly occurs as a result of ground water entering into walls through pores in brickwork or stonework. Buildings with a damaged damp proof membrane are most likely to be affected.
Typical signs of a rising damp problem include:
- Discoloured or crumbling walls
- Peeling paint or wallpaper
- Decay of timber floors
- Damp musty odour
Contrary to popular belief, rising damp is not as common as contractors would have you believe. This problem typically occurs in foundations that extend beneath the ground water table. Water can rise up through the structure via a process that is referred to as ‘Capillarity’. The factors that effect the amount of moisture absorbed and the height that is impacted can be categorised into three groups.
