Damp Proofing

Professional damp proofing

What is damp proofing?

Damp proofing is a generic term for the process which stops moisture passing through the external wall of a property into the interior.

If the dampness continues for a period of time a building can suffer from damp related problems, such as wet rot, mould and dry rot.

A Cannon Clarke surveyor can inspect your building, correctly diagnose the reasons for the damp problems and specify a suitable course of action accordingly.

External weatherproofing

In some properties a combination of porous building materials and an exposed location can lead to the penetration of moisture through the building structure which is the result of wind-driven rain rather than dampness originating below ground. This can often cause damage to internal plaster and decorations and contribute to fungal decay in timbers.

Cannon Clarke Surveyors are fully trained to identify this relatively rare set of circumstances and to specify an appropriate solution. This is usually the application of a breathable, acrylic-based surface coating to the exterior of the building. In some circumstances specialist re-plastering will be required to make good internal surfaces affected by the penetration of water. If this is the recommended approach then Cannon Clarke will be able to supply and apply the necessary coatings to provide a long term solution.

Rising damp can lead to rotten timbers and deterioration of plasters and other wall coverings. In addition, mould and efflorescence (white salts) may form on affected walls.

The presence of rising and/or penetrating damp needs to be carefully diagnosed in order to ensure that this is not confused with other sources of dampness. Our team are highly experienced and will be able to inspect your home with confidence.

We can offer a variety of remedies for rising and penetrating damp and our surveyors will assess which damp proofing system is most appropriate for your particular property and specific situation. Most treatments involve the injection of special-purpose chemicals into the affected walls to create a barrier between the damp ground and the dry structure above. We regularly review the treatments available to ensure that the best products are presented to our customers. We are currently recommending the use of either Aida Injection Cream or Vandex Injection Mortar although we may consider other products in specific situations.

As well as the introduction of a damp proofing system it is often necessary to repair plaster where this has been damaged by the presence of rising damp.  We have been installing new damp proofing systems and remedying damp proof course failure for 25 years, with excellent success.
