We summarise the dampness that affects the buildings we look after by putting them in the following categories…

  • Condensation - Defined as warmer moisture laden air that condenses on cooler surfaces. This is easily recognised in our homes. There is an another form of condensation, which may occur within a wall or cavity, but we will stick to the most common one. To remedy condensation within a household would consist of manipulating the internal atmosphere by several means (either manual or mechanical) or introducing dehumidifiers. Each situation would need to be assessed on its own merit.

  • Rising Damp - (Fig 4a) Defined as ground water rising up through porous masonry. Basically the same principal as a wick in a paraffin lamp. There are several developed methods of creating barriers to stop or restrict the rise of ground water in lower walls. Some work and some don’t, but again each situation has to be judged on its own merit. We use “Alternative Applications” we can apply which are far more environmentally friendly, cost effective and non-toxic. Should there be any damage to the interior plaster as a result of the mineral salts which migrate to the surface with the rising and evaporating ground water, (Fig 4b) the plaster can simply be removed and reinstated ensuring the incorporation of a good salt retardant additive.
  • Penetrating Damp (above ground) - Defined as moisture being allowed to penetrate the building fabric due to any number of external defects such as defective roof coverings, gutters, pointing, chimneys (Fig 4c) etc. The simple solution to this is to fully investigate and carry out repairs as required.

  • Lateral Penetration (below ground) - Earth retaining walls, (Fig 4d showing high groun levels) basements, and ceilings. Unless you can take the earth away, you will end up having to create a physical barrier internally. In severe cases, it may be necessary to incorporate drainage internally as wellas the aforementioned. Again we can use “Alternative Applications” which we can apply avoiding the need for chemical intervention.
