Further Information


Dry Rot

Signs of dry rot were found in the roof timbers.  All wood affected by dry rot was removed from the building.  Any timbers to be retained were treated with a boron treatment, to help prevent against further dry rot outbreaks.  The masonry in infected areas was sterilised using a fungicidal solution to eradicate and protect against dry rot infestation. 

Rising Damp

The ground floor walls at low level had significant levels of damp.  After a thorough survey, the surveyor established that the damp was likely caused by an ineffectual or missing damp proof course.  The ground level and internal floor levels were to be finished at the same level;  according to the code of practice for installing remedial damp proof courses, the chemical injection dpc was to be injected 150mm above finished floor level, resulting in the potential for damp to cross below the dpc, into the property.  It was therefore recommended that a cementitious waterproofing compound (tanking) be applied below the damp proof course.

Woodworm Treatment

All retained timbers in the roof were sprayed and treated for woodworm infestation.
