What is damp?
Damp is a common problem, that properties across the UK will suffer from at some stage. If untreated, damp can be extremely damaging to the structure and fabric of your home.
If you are unsure what causes structural dampness, it is the presence of unwanted moisture in the structure of a building. Dampness is caused by either the result of penetration from outside or damp created within the property.
Why does damp occur?
A high proportion of damp problems in buildings is caused by penetrating damp and rising damp. In most cases, dampness is caused by defects or damage to a building like defective roof coverings, render or rainwater gutters and downpipes.
Where can dampness be found?
Dampness can be found anywhere in a building and can affect all types of properties, old and new. It is important that when dampness is suspected you get an accurate diagnosis to determine the type of damp and the cause of the problem.
How can I identify dampness?
At Damp Proofing Specialists, we use a wide range of instruments and techniques in conjunction with our experience to investigate and identify the presence of excessive moisture in buildings. It is important that a professional surveyor assesses your property to determine what is causing the damp.
Is my property damp proof?
It is vital that your property has a damp proofed structure that will protect the building from problems such as penetrating damp, rising damp and below ground damp.
A Damp Proofing system is a moisture control barrier that can be applied to walls, floors and the structure to prevent moisture from passing into the interior living spaces. Damp issues in buildings is extremely common in the UK and damp remedial treatment is one of the most common property care repairs.
What is damp proofing membrane?
The ground below your floor should have a damp-proof membrane to stop damp coming from the ground and a damp-proof membrane can be applied to the internal side of an external wall to stop damp getting to your plaster and decoration. These membranes are also used on wall areas that are below ground level that can be affected by penetrating damp from the ground.
Why remove plaster during damp proofing?
Plaster must be removed during the damp proofing process as rising damp coming from the ground not only brings moisture but also brings hygroscopic salts, nitrates, and chlorides.
Hygroscopic salts attract moisture from the atmosphere. These salts will contaminate the plaster inside the property and even after a remedial DPC has been inserted the salt contaminated plaster can still become damp. It is vital that contaminated plaster is stripped and replaced during the treatment.
