**Moisture Mapping** is a non-destructive testing method used to determine the moisture content of wood. It is a valuable tool for woodworkers, builders, and homeowners alike, as it can help to identify areas of moisture accumulation that could lead to problems such as mold growth, rot, and structural damage.
### Wood Moisture Content
Wood moisture content is the amount of water vapor present in wood, expressed as a percentage of the oven-dry weight of the wood. The moisture content of wood affects its physical and mechanical properties, such as its strength, stiffness, and dimensional stability.
The moisture content of wood can vary depending on a number of factors, including the species of wood, the climate, and the storage conditions. In general, the moisture content of wood will be higher in humid climates and lower in dry climates.
### Can Wood Contain Over 100% Moisture Content?
Yes, wood can contain over 100% moisture content. This is known as **supersaturated wood**. Supersaturated wood occurs when the wood has absorbed so much water that it is no longer able to hold it all in its cell walls. The excess water is then held in the wood’s capillary pores.
Supersaturated wood is often found in areas that are subjected to prolonged periods of high humidity, such as in swamps or rainforests. It can also occur in wood that has been submerged in water for an extended period of time.
Supersaturated wood is not as strong or durable as dry wood. It is also more susceptible to rot and decay. Therefore, it is important to avoid exposing wood to conditions that could lead to it becoming supersaturated.
