This is dampness that seeps through walls from the surrounding earth or by rainwater penetration. BRIXHAM DAMP PROOFING offer a wide range of Tanking and Cavity Drain Membrane systems (which will enable the conversion of a wet basement into a habitable and useful living area) and water repellent treatment (applied externally to walls above ground level). We can advise and provide the service you require.
Dry rot (Serpula lacrymans) can destroy in months what the equally determined wood-boring insect larvae may take years to achieve. Caused often by a combination of dampness and insufficient ventilation, it results from such causes as defective gutters, roof faults, blocked underfloor air vents, bad pointing, and rendering, the lack of an effective damp proof course or the sealing of any space into which moisture has access. It is a primitive form of vegetable life that derives its nourishment from timber by destroying the cellulose, thereby depriving the wood of all its natural strength. Once established, it grows rapidly by pushing out fungal strands (hyphae) even through thick masonry, in its search for more timber on which to feed. Dry rot will grow sheets of a substance known as mycelium which is foul smelling. From this, fruiting bodies (sporophores) may eventually form producing millions of airborne spores which carry the infection elsewhere, not only through the building but to other buildings where conditions for germination occur now or in the future.
Dry rot is a malignant destroyer than can remove all the strength from buildings and on occasions when it has been permitted to go unchecked, has been responsible for their complete collapse. With any fungal decay, it is important to bear in mind that, like and iceberg, what a property owner has seen might only be the tip of the problem.
This is probably the most serious source of damp in buildings. It is caused by water rising, through capillary action, in the porous material of which most walls are constructed. An efficient damp proof course will prevent moisture from rising but, in older houses, it may have broken down, or the house may have been built without one. BRIXHAM DAMP PROOFING have a range of systems available, allowing us to treat almost any type of wall construction. Properties that have suffered from rising damp usually need a certain amount of specialist re-plastering to eliminate the secondary problem of moisture-attracting mineral salts (hygroscopic salts) which so often contaminate plaster. BRIXHAM DAMP PROOFING have a full re-plastering service.
There are other forms of fungal decay that attack property apart from dry rot, the principal one being the wet rot (Coniophoraputeana). Although not so serious, they can still be a cause of structural problems in buildings and should be dealt with to prevent deterioration
Wet rot decay is normally restricted to excessively damp timber and can be easily mistaken for dry rot in certain circumstances. Expert advice is, therefore, necessary to determine the precise form of attack. Treatment may sometimes only necessitate the replacement of unsound timber and possibly the application of fungicide to the replacement and adjoining timbers. The damp condition that has caused the infection must be eliminated at the same time.
