This thesis examines the influence of microwave pretreatment of wood modification and Bethell impregnation methods on the treatability of Norway spruce (Picea abies) in consideration with its mechanical properties. The aim of this work was to establish the intake of impregnants (preservatives) and the depth of penetration in transverse direction of each treatment group with impregnated specimens. Further experimental examinations that were focused on the assessment of mechanical wood properties and the comparison with references (non-impregnated specimens) followed. Results showed that the intake of impregnants and the depth of penetration increases with time (modification) of the impregnation treatment. In contrast, microwave wood treatment actually decreases those values. Neither microwave modification nor adjustment of impregnation method had an influence on mechanical wood properties.
