Fungal Damage

Wood-destroying fungi and dry rot

In the case of a fungal infestation, it must first be determined what type of fungus is involved, because the type and extent of the remediation measures depend on it. A qualified expert must carry out an investigation to determine the necessary control measures required. With the possibility of the growth of fungus strands through the brickwork into adjacent rooms, these must also be examined for infestation. The real dry rot must doubtlessly be determined. If this cannot take place microscopically, laboratory examinations must be carried out. Careful investigation of the cause of the increased moisture in masonry and wood is required. The source of moisture must be eliminated. It must be ensured that renewed moisture penetration does not occur.

The real dry rot is the most dangerous and most difficult fungus to control in buildings. It is able to attack wood with a wood moisture in the fibre saturation area and to moisten dry wood for further infestation by transporting water. It grows through brickwork and other inorganic materials and attacks adjacent wooden components.

Through structural measures, a normal moisture content of wood (below 18%), air and masonry must be restored. It must be ensured that moisture contained in wood and other building materials can escape as quickly as possible and that no new moisture is absorbed. If necessary, drying units (e.g. condensation dryers) must be used for this purpose.
