Rising damp

Rising damp is a problem for every home-owner

The process of rising damp

In brick and mortar walls, moisture or damp can rise due to the capillary function. This is usually because of the fact that the wall is in direct contact with natural sources of water in the ground. This is also the reason that moisture damage of this kind is less often found in newly constructed buildings due to their concrete foundations.

The consequences of rising damp

Rising damp is usually limited to around 1.5 metres above ground level. Typically, moisture damage of this sort is easily recognised by a discoloured zone which is lined with salt bloom around the edges. In addition, it is very likely that other areas on the wall’s finish and plasterwork have been visibly damaged.

H.V.O. offers a unique solution for these problems by a special injection technique that combats the effects of rising damp from the ground up. We inject a patented micro-emulsion directly into the wall where it comes into contact with the moisture. This process creates an impenetrable layer that provides lasting protection!

The signs of rising damp

In case of rising damp, the following signs may be observed:

  • Fogging on windows
  • Rotting woodwork
  • Stale odours in the residence
  • Fungi on, for example, walls
  • Separation of paint
  • Salt bloom
  • Rotting beams in case of wooden floors
  • Powdered residue on affected areas

Apart from the obvious damage to the structural integrity of the residence, health hazards are a factor as well. A few examples are as follows:

  • Stiff muscles
  • Worsening rheumatic problems
  • Bronchitis
  • Astma
  • Allergic reactions
