Damp proofing is a protective process to ensure moisture cannot pass through the walls of a building to the interior. Damp proofing places a barrier in walls which prevents rising damp, with other methods available to prevent penetrating damp problems prevalent in modern homes. Using a Peter Cox domestic damp specialist to eliminate damp problems in the home can also eliminate the possibility of future damp-related problems such as wet rot, dry rot, and mould.
Rising damp is unhealthy, unsightly and can lead to timber decay and heat loss. It carries with it hygroscopic ground salts such as chlorides and nitrates, which can absorb moisture from the atmosphere, leading to damp in walls in conditions of high relative humidity.
The cyclical nature of the crystallisation and rewetting of these salts can break down internal plaster and ruin internal decorations.
What causes damp?
What appears to be rising damp can be due to various factors – the failure of an existing damp proofing course (dpc), bridging due to the raising of external ground or internal floor levels, or in older buildings, the complete absence of a damp proofing course. Damp in walls may also be due to condensation or an incorrect re-plastering specification. Other factors such as failed rainwater disposal systems have to be taken into account.
If you suspect your home has fallen victim to damp problems, call a Peter Cox damp surveyor, who will inspect your home, give you an accurate diagnosis and inform you of the best course of action and which kind of Peter Cox damp proofing service would best suit your needs.
Damp proofing your home
Where rising damp is diagnosed, Peter Cox will install a remedial damp proof course using their DryWall Silane Diffusion system, the very latest in damp proofing technology.
This involves the introduction into the wall of a concentrated thixotropic silane/siloxane ‘cream’ to form a barrier against rising damp. As the cream slowly diffuses, it also releases a silane vapour which reacts with the silica in the masonry to form a water repellent resin.
No liquid is involved so the wall is quicker to dry out and it is not injected under pressure which means that there are no problems with party walls.
The benefits of choosing a Peter Cox DryWall damp proof course:
- Low hazard, non-caustic and solvent free
- Non-flammable and virtually odourless
- Recommended for brick or stone
- Suitable for walls of any type and thickness
- For both internal and external use
- Can be used on 280mm cavity brick walls
- The system carries an Agreement Certificate No 02/3976
The Peter Cox DryWall damp proof course is environmentally friendly and financially efficient – damp walls lose heat a lot quicker than dry walls and using a Peter Cox damp proofing expert to eliminate this problem will save both money and energy.
It is important to note that the provision of a barrier against rising damp will only prevent further moisture rising from the ground and that all other sources of dampness must be eliminated as well. Our surveyor will advise you on this.
