Wet Rot
Persistent rain water penetration, faulty plumbing or some similar
major leakage into the fabric will cause the high moisture levels in
wood ('10-50%) which are necessary for wet rot to develop. There are many species of fungi that can cause wet rot. The wood Characteristically splits along the grain where decayed. There is usually little surface mycelium. Fruit bodies are not commonly produced. There are numerous types of wet rot. Although they have their own characteristics and may attack timber in different ways they all have common features the most important of which being they all limit their. Attack to damp timber, Unlike dry rot, there is no threat to masonry or
dry timbers.In view of this, extensive chemical treatment is not generally necessary and remedial action is directed towards removing the moisture source, Improving ventilation and replacing affected timbers.
Remedial Treatments
There are various remedial treatments which are used to combat rot and to reverse damage to an affected building. The treatment or combination of treatments used will depend on both the extent of rot damage and the particular needs of a building and its occupants.
Chemical Sterilisation Treatments
Where our qualified surveyor deems it necessary to use fungicides to treat dry rot, the chemicals, which are usually water based, and contain extremely low concentrates of active ingredients are applied only to those areas of wall fabric or at risk timbers identified by the surveyor. There are a variety of methods by which this can be achieved, But the type of solution and method of application depend upon the type and extent of decay and the extent of structural deterioration to colonized timber.
