Wood Deterioration, Protection and Maintenance provides an up to date discussion of the natural durability of wood, wood degradation processes, and methods of structural and chemical protection of wood. Modern active substances in wood preservatives and the relationships between preservative properties, the anatomical structure and moisture content of wood and protective processes involving pressure and/or diffusion driving forces are fully illustrated.
