Modification of wood by introducing carbon particles through impregnation under vacuum conditions was
studied; water resistance and spring-back behaviour of the wood were evaluated. The wood was subjected to
different combinations of impregnation and densification processes. A water solution with 1%, 2.5%, and 5%
carbon was used for impregnating the wood. The impregnation and thermal-hydro-mechanical densification
treatments (THM) were performed on four types of wood: Populus nigra (Black poplar), Picea abies (Spruce),
Abies alba (European fir), and Fagus sylvatica (Beech). The physical and mechanical characteristics were
evaluated and compared for all samples in relation to the percentage of carbon. It was shown that the addition
of 2.5 and 5% carbon particles positively affected the mechanical behaviour of spruce wood. In the case of
other woods, biochar had no effect or at some percentages it had a negative effect. In the densified samples the
presence of carbon lowered the set-recovery values. Spruce had the best waterproof surface.
Keywords: wood modification, biochar, moisture resistance, spring-back behaviour
