Wood Preservation in Belgium

IRG/WP 3170

M Stevens, R Cockcroft

The report reviews wood preservation activities in Belgium and notes the number of authorized treatment depots has doubled during the past five years. It lists the timbers that are allowed to be used for joinery and constructional building purposes and the preservatives and treatments with which these timbers may be protected. In Belgium not only have the wood preservative product and its treatment method to be approved, but the depot where the timber is to be treated has to be authorized as well. Belgian procedures for approving the use of a preservative are detailed, together with the various chemicals that have been accepted, and the concentrations at which these may be used. A survey has indicated that during 1980 four times as much sawn timber and joinery were treated by long term immersion with water-borne preservatives than were impregnated under pressure, although of the total sawn timber treated nearly 60% was treated with organic solvent preservative either by deluging or dipping. The report lists the various brands of wood preservative products, together with their relevant specifications, which have been authorized and the names and addresses of the treatment stations with the names of the products which each employs. The organizations which influence and control wood preservation activities in the country are noted as well as the various research centres where different investigations into the subject are carried out. For wood preservation most of the Belgian Standards are derived from the European Standards.
