Research on the biological degradation of wood using a resistograph

Assessment of the risk level of timber structures is still a challenge due to the lack of comprehensive in situ research methods. This problem is particularly important in the context of historic buildings, which, despite their seemingly solid construction, may hide significant damage. Many such facilities are used without awareness of the risks associated with material degradation. Invisible damage can lead to serious construction disasters, especially in places where beams lose their support in the walls due to the destruction of the wood at their ends. These are the places where the most serious threats occur, and yet the technical condition of these elements is practically not assessed in these areas. The article emphasizes the need for continuous research on the biological degradation of wood and the use of advanced measurement methods, such as a resistograph, to more accurately assess the technical condition of timber structures and effectively prevent their degradation.
