Abstract
Ce procédé consiste à appliquer une couche extérieure souple formant barrière sur un objet, tout au moins sur la partie la plus susceptible de subir une décomposition, à intercaler une substance bitumineuse entre la couche barrière et l'objet, puis à chauffer cette substance de manière à la faire fondre suffisamment pour la lier intimement à l'objet. La couche barrière, qui peut être une pellicule plastique ou une matière plastique thermorétractable, peut être façonnée en une enveloppe, ou bien en avoir la forme, et être thermorétrécie sur l'objet. Le procédé réalisé au titre de cette invention s'avère particulièrement efficace pour protéger de la décomposition les parties vulnérables d'objets en bois de forme allongée, tels que des pieux ou des poteaux de clôture.
