Damp proofing a building is vital. Moisture can infiltrate and start to disintegrate bricks, making a structure dangerously unsound. Additionally, nasty little creatures, molds and germs flourish in the dampness, which can lead to a variety of horrid illnesses.
In most cases, according to experts, water from the earth is drawn into a building at foundation level, soaked up in a naturally occurring activity called capillary action. Porous brickwork is an ideal material through which the damp can spread. This is more popularly known as rising damp and can be demonstrated, often on older brick buildings, by a white salty ring around the building. For this you need to make pores into the wall by using Concrete Chainsaws.
Rising damp can be treated with one of a number of painted on solutions. An epoxy dampshield is a hard wearing substance which can be used on external or internal walls and are solvent and odour-free. Microporous, this substance will let moisture escape from the building but does not allow bacterial growth, so no mould. The great thing about using an epoxy coating is that ordinary emulsion paint can be used over the top.
Alternatively, a polypropylene membrane can be attached to contaminated walls to create a dry area, with plasterboard applied on top. This allows for air circulation and provides additional insulation. Sealing tape is required for making joints and the process can be carried out very quickly, lasting, so experts say, up to 50 years.
Anyone worried about rain, whether they have rising damp or not, can apply one of the many weather proof products available in the shops. These will act as a barrier and protect from rain, damp and staining and can be applied to bricks, masonry, wood and plaster.
Damp caused by condensation in the air, i.e. that you would find in a poorly ventilated bathroom, is a common problem for many householders. Characterised by dark spores in corners of rooms, windows or behind curtains, the mould should be washed away first, then ventilation maintained.
