Within the framework of this research, the biological durability of two different wood species (Pinus sylvestris and Fagus sylvatica), impregnated with beeswax was investigated. The durability was tested according to the standard EN 113, and with a laboratory-scale soil contact test, based on the standard ENV 807, using modified parameters. The aim of the tests was to increase the biological durability of the samples treated with beeswax by impregnation. Test specimens modified in this way do not have any toxic effect on the environment. Unimpregnated beech and Scots pine samples showed high decomposition during both decay tests. The damage of the impregnated samples was markedly lower. Beside mass loss, this was confirmed by the visual inspection of the samples after soil exposure under laboratory conditions. Impregnated samples showed low degradation level compared to the controls.. SEM imaging showed that beeswax filled the lumens and separated most of the cell walls from the hyphae, which slowed the spreading of the fungi in the wood.
