A material and method for treating timber. The material comprises a preservative and a carrier. The carrier is selected such that it remains mobile within the wood and provides for migration of the preservative within the treated wood. By providing a carrier which is mobile within the wood, the timber has a 'self healing' effect wherein the carrier/preservative migrates to any freshly cut or exposed surface of the wood to thereby redistribute and treat such a surface within the preservative and hence maintain integrity of a treatment envelope surrounding the wood.
Cette invention concerne un matériau et un procédé de traitement pour bois débité. Le matériau se compose d'un agent conservateur et d'un agent vecteur. Le vecteur est choisi pour son aptitude à conserver sa mobilité à l'intérieur du bois et à faire pénétrer l'agent conservateur dans le bois traité. L'emploi d'un vecteur mobile a sur le bois un effet de régénération naturelle. Le vecteur/agent conservateur atteint toute surface du bois fraîchement coupée ou exposée pour s'y diffuser, traiter ladite surface et maintenir par là l'intégrité d'une enveloppe de traitement autour de la pièce de bois.
