Rising Damp

What is rising damp?

Rising damp results from water being drawn up from the ground by capillary action. Due to natural evaporation from the surface of walls, rising damp rarely occurs above a height of 1.5 metres unless forced higher by being sandwiched between 2 impervious layers of render, paint or wall paper. Temporary measures like cleaning the surface, re-plastering or repainting can actually make the situation worse.

The rising damp also carries with it hydroscopic salts (nitrates, sulphates and sodium chloride) and as dampness evaporates from the wall surface the salts are deposited in the plasterwork, which build up into a concentration that can absorb moisture from the air making the situation critical.

Why does rising damp occur?

Rising damp may be caused by a lack of damp proof course in the construction, or by soil debris bridging the existing damp proof course. Other effects such as garden beds draining under the house or concrete paths directly against the wall, can often enhance the problem.

Chemical Injection

Pressure injection is carried out along the identified damp-course line using a specialised silicone-based emuslion. The system is installed through precision drilled injection points, where the purpose designed pumps and lances deliver the material to form a new, effective damp proof course. This method is both practical and environmentally responsible, making it a trusted choice for preventing rising damp.
