However, it also believes rising damp is often misdiagnosed.
Therefore, it is important that the investigations into dampness are undertaken by a trained and competent surveyor who can recognise and understand the problem.
The PCA recommends the surveyor who undertakes investigations has been awarded the CSRT (Certificated Surveyor in Remedial Treatment) qualification.
Decayed skirting boards, crumbling or salt stained plaster, discolouration and staining, decayed timber floors and peeling paint and wallpaper are all common when walls are affected by rising damp. These defects are not always evident but when they are evident a specialist inspection is always recommended.
Most types of masonry used in the walls of buildings will allow some water movement by capillary action; however, this is usually controlled by a physical barrier or damp proof course. If this physical barrier is absent, has broken down or is damaged then it is often possible to install a remedial DPC to control water rising from the ground.
Water rising from the ground often introduces contaminating salts into the walls and plaster coats. This contamination will often result in a need for the plaster to be removed and replaced using specially formulated salt resistant plasters.
The PCA’s new CPD "The Treatment of Rising Damp and Preservation of Timber" outlines the strengths and limitations of damp diagnostic procedures, introduces the latest materials used for the treatment of rising dampness in buildings, and also gives details of modern methods used for damp cellar and basement conversion.
A brief history of timber preservation and the latest treatment formulations, together with the control of dry rot/fungal decay in accordance with BRE Digests are also covered.
The trade body – which represents the UK’s structural waterproofing, wood preservation, damp-proofing, flood remediation and structural repair sectors – is noted for its training and technical expertise.
PCA training is a key role of the trade body and underpins its reputation as a major educational provider. The Association already has a well-established training programme that has operated for decades.
