Rising Damp Specialists
A common misconception is that the presence of surface mould growth is indicative of a rising damp problem. This is commonly not the case as mould growth needs clean, pure moisture to germinate and grow. If rising damp is present then wall surfaces will be contaminated with mineral salts and as such will prohibit mould growth taking place. If you are experiencing problems with mould growth to wall and ceiling surfaces, together with mould contamination to general fabrics, please visit our Condensation page for more information.
Porous building materials and mortars in which they are bedded can allow ground water in the form of Rising Damp to contaminate the structure. Rising Damp brings with it ground salts which include chlorides and nitrates which are hygroscopic or moisture attracting. These salts become concentrated at the point of evaporation, usually around the maximum height of the Rising Damp.
The maximum height of Rising Damp will be affected by a combination of the following factors:
- The availability of Ground Water
- The porosity and pore size of the building material
- The thickness of the wall
- The rate of evaporation of water from the wall.
Dampness that may appear to be Rising Damp may occur in buildings old and new for many reasons.
Our experience shows that not all perceived Rising Damp problems are in fact true Rising Damp. It is not uncommon for buildings to suffer from dampness from more than one source and therefore a professional inspection and diagnosis can save time and money being spent on work that may not solve the problem being experienced.
The correct diagnosis of the true cause of dampness in buildings is essential. Protectahome’s experienced knowledgeable Damp Proofing Surveyors can employ various instruments on site to assist with diagnosis as well as taking samples for laboratory analysis where appropriate.To arrange for one of our experienced Damp Proofing Surveyors to visit a property Contact Us on 0800 055 6966 or email us now via firstname.lastname@example.org.
