Below Ground Penetrating Dampness/Water
What is below ground penetration dampness/water?
Below ground penetration is where the external ground level is higher than an external floor, a risk of penetration occurs. Most soils are porous which result in the absorption and migration of water. When in contact with an absorbent structure, water from such soils can permeate. The result can be a damp or wet wall.
What are the signs of below penetrating dampness/water?
- A damp wall frequently appears darker than other wall sections, salt formations may develop on the surface.
- Wallpaper and paint may start to blister and peel off.
- There could be a “musty” smell.
- Black mould growth occurs where wall surfaces are damp and cold, and ventilation and/or heating are inadequate.
- A wet wall may exhibit some or all the above but will feel colder and wet. A hand wiped across the wall surface will become wet, a thin, moving film of water will be observed flowing over the whiped area.
Is below ground penetrating dampness/ water a problem?
Below ground penetrating dampness/ water are both hazardous to health and detrimental to building structure.
