Durability Performance of Timber Grown on Ex–Mining and Bris Soil

Timber has been material of choice since time immemorial. However, under certain conditions of use and storage, timber is easily degradable by biological elements such as fungi. This causes immeasurable losses each year. Therefore, the cause and effect of timber degradation by fungi can hardly be overlooked. The processes of timber decomposition by fungi, and the technology used for protection against them have been continually studied either in the field or laboratory condition. Durability is one of the key performance factors used to assess the suitability of a timber species for a specific application. The durability rating of a species is based on the ability heartwood of that species to resist decay fungi and insect pests (including termites). This paper entails to the ability of some species, namely Acacia, Khaya and Merawan, which were grown on unproductive land such as ex-mining or BRIS soil which can provide some degree of natural durability due to the presence off heavy metals.
