Wood moisture content refers to the amount of water present within the wood’s structure. It is typically expressed as a percentage of the wood’s dry weight. In general, wood that contains less than 20% moisture content is considered dry, while wood with more than 30% moisture content is considered wet.
Yes, it is possible for wood to contain over 100% moisture content. This condition is known as “over-saturation” and occurs when the wood absorbs water beyond its capacity to hold it. In over-saturated wood, the cell walls are filled with water and the intercellular spaces are also saturated.
The maximum moisture content that wood can hold varies depending on the species, density, and environmental conditions. Some species, such as oak and maple, can hold up to 120% moisture content, while other species, such as pine and spruce, can only hold around 80% moisture content.
Over-saturated wood can experience several negative consequences, including:
If wood is over-saturated for an extended period, it can lead to irreversible damage and compromise its structural integrity. Therefore, it is crucial to control moisture levels in wood to prevent over-saturation and maintain its durability.
