Moisture Mapping is a crucial technique for assessing the moisture content of wood, enabling informed decisions about its use and maintenance. Understanding wood moisture content is essential for preventing problems such as shrinkage, warping, and decay. ### Wood Moisture Content The moisture content of wood is the ratio of its weight when wet to its weight when dry. It is typically expressed as a percentage and can vary depending on factors such as wood species, storage conditions, and environmental humidity. ### Can Wood Contain Over 100% Moisture Content? Wood can indeed contain over 100% moisture content when it is fully saturated with water. This is known as the "fiber saturation point" and occurs when the wood's cell cavities and cell walls are filled with water. Beyond this point, any additional water is referred to as "free water" and can result in waterlogging.
