Impregnation of timber with tannin as a mean of improving its dimensional stability

IRG/WP 92-3695

J S Machado

The results of a joint project carried out at the Timber Division of LNEC under the 2nd research programme of the CEC DGXII - "Wood as a renewable raw material" entitled "Stabilization of wood by impregnation processes" is presented. Pieces Maritime pine timber was impregnated with tannin under pressure to see if the treatment with tannin improved the behavior of wood regarding its dimensional stability. The results of the outdoor exposure in two different sites in Portugal and in one site in Spain will be presented in this paper.
