Damp proofing is the protective process to ensure moisture cannot pass through all walls in contact with the ground or floors, into the interior of a building through various damp proofing treatment methods. There are many different causes of damp within homes and businesses, from rising damp, penetrating damp or through condensation problems.
Rising damp can affect all buildings causing dampness problems in exterior and interior walls.
The main issue with penetrating damp is locating and preventing the source of water from damaging your property.
Damp in your home can be unhealthy, unsightly and can lead to timber decay and heat loss. Rising damp carries hygroscopic ground salts from the ground, which absorb moisture from the atmosphere leading to the salt breaking down internal plaster and decorations, ruining them. If left damp problems can cause severe problems to a buildings structure. Damp can be detected through a musty smell, or the appearance of mould, wet rot or dry rot in skirting boards, roof or floor timbers.
If left untreated, damp in the home can have serious health implications. Mould, wet rot and dry rot can all release spores into the atmosphere which can be harmful when inhaled, particularly to those with asthma; a condition provoked by the presence of increased moisture and condensation characteristic of damp problems.

Concrete floors are susceptible to rising damp through the same capillary process as walls.
The most common form of dampness in a building which can lead to unhealthy living conditions. It is noticeable when black mould begins to appear.
Damp can be caused by various factors. The most common form of damp problems are caused by condensation, rain penetration, rising damp or from high ground levels.
If your property does not have a damp proofing course (DPC) or the damp proofing cause is bridged or faulty, dampness will be able to rise through the ground into your walls.
Water ingress can also be a major cause of damp within a property, leading to severe issues such as wet rot. Unlike rising damp, penetrating damp tends to be localised in one area, so once the source of the water ingress is removed it should solve the problem.
Condensation is caused by a build up of water vapour (humidity) from every day living becoming trapped inside a property with inadequate ventilation. When temperatures inside a property drop the capacity for air to hold moisture reduces, meaning saturated air in the atmosphere turns to water droplets (condensation) on cold surfaces such as walls and windows.
Wet rot occurs when there are high levels of moisture, damp or condensation in a building. Find out how to identify wet rot in your property here.
