  Dry rot

Dry rot is a fungus which develops in the presence of dampness and cellulose material (generally, untreated wood, cardboard, etc.).

It particularly affects areas which are poorly ventilated, damp, dark and relatively warm (between 5 and 25 °C).




Application of the dry rot treatment


In the event of an attack of dry rot, the work should be performed as follows:


  • - Identify the focal point of the dry rot

  • - Diagnose the source of humidity

  • - Limit the zone to be treated calculated in square metres

  • - Sampling and laboratory analysis of the fungus (U.C.L- Louvain-la-Neuve)
Dry rot

2- Elimination of the cause of the development of the fungus

3-Preparatory work prior to treatment



Treatment of dry rot : treated woodworks
  • - Discard, remove and burn all infested and adjacent wood

  • - Strip all plasterwork down to the masonry

  • - Brush the walls until you can no longer see the filaments (rhizomes) on the surface of the wall

  • - Replace and/or reinforce all contaminated woodwork

4-Curative treatment of dry rot

  • - Drill the walls in a staggered pattern, every 25 cm.
    These holes should be drilled in the joints of the masonry over an area one metre larger, in all directions, than the area affected by surface fungus. The depth of the holes should equal 2/3 of the thickness of the wall.

  • - Inject a fungicide product

  • - Spray the surface with a curative product


Fungicide treatment of dry rot

  • 5-Products and quantities

  • Basilit B 85:
    Based on boric acid, this product in aqueous phase is recognised by the Minister of Health under no. 5087B

  • Basilit pcx Curattack:
    micro-emulsion in aqueous phase. This product is recognised by the Minister of Health under no. 496b

    These fungicides are non-toxic to human beings and contain no PCP or lindane. Their effectiveness has been proven against dry rot, Hennebert, Boulenger, Balon, Edition Ciaco.

    The quantity of product to be injected depends on the thickness of the wall: a wall 35 cm in thickness requires an average of 5 to 6 litres of product per square metre.




6-Treatment of the adjacent wood

Any adjacent wood should be treated with a projection of Basilit Curattack, fungicide and insecticide product intended to preserve wood from the attacks of insects and fungi.



All walls treated are guaranteed for a period of 10 years
