Wood seasoning is one of the most common processes in the timber industry which, if carried out properly, ensures high quality material. What are the risks involved in using structural timber with excess (very high) moisture content? Such timber has inferior strength parameters. After drying, it has reduced cross-sectional area and ends up with lower loading strength than is required by the original structural design and is prone to cracking and warping. It also susceptible to mould and fungus growth and, consequently rotting. Seasoning is leads to reduced cracking or, alternatively, to induce it so that the items which demonstrate excessive cracking can be classified as unfit for structural purposes and used as material for making smaller items.
