Wet & Dry Rot

Wet & Dry Rot

Wet rot is the term used to describe all wood rotting fungus other than Dry Rot (Serpula Lacrymans). It is generally confined to those timbers in contact with wet or damp masonry. Treatment of the fungus requires that the source of dampness is removed, decayed timbers treated or replaced and a physical barrier installed to prevent further damage from damp masonry.
Basement Waterproofing

Basement Waterproofing

Tanking is the process used to hold back damp penetration through wall structures below ground level. Quadrant Damp Proofing uses two main techniques:

Cementitious structural waterproofing: this involves applying a waterproof layer of plaster to prevent moisture from penetrating. This is only applicable if the structure of the building itself can withstand the added pressure from water already present in the walls. The building must be in a stable environment (no subsidence) and should not be subject to vibrations which may cause the plaster to crack and leak.

Cavity drain membrane: a waterproof membrane is attached to the walls so that moisture will flow down behind the membrane and via drainage channels to where it can be conveniently pumped out. This method is ideal if your structure cannot withstand the added pressure of water against the walls, or if your home is subject to vibrations as previously mentioned.

If rising damp is found in your property it can easily be treated by an injection of a chemical damp course, followed by the removal of the salt affected wall plaster. In some cases the wooden skirting boards may need replacing due to decay from wet rot. The walls will generally need to be re-plastered with sand cement render to hold back the residual moisture and salts. We will fully explain the entire process during the course of the survey.
