Wood Moisture Content
Moisture content in wood refers to the amount of water present within its structure. It plays a crucial role in the properties and performance of wood products.
Wood absorbs moisture from the air and its surroundings, and its moisture content can fluctuate with changes in environmental conditions.
Can Wood Contain Over 100% Moisture Content?
It is possible for wood to contain moisture content exceeding 100%. This condition is known as “fiber saturation point.”
At the fiber saturation point, all the available binding sites within the wood fibers are occupied by water molecules. Any additional moisture will occupy the cell cavities and spaces between fibers, not bound to the wood structure.
When wood reaches fiber saturation point, its physical and mechanical properties are significantly altered. It becomes more flexible, weaker, and prone to decay. It is crucial to manage wood moisture content to maintain its structural integrity and prevent moisture-related problems.
Moisture Mapping
Moisture mapping involves measuring and recording the moisture content of wood in various areas of a structure or product.
This process provides valuable information about the moisture distribution and can help identify areas with elevated moisture levels that may require attention or treatment.
Moisture mapping is commonly used in:
- Building inspections
- Restoration and remediation projects
- Quality control in woodworking
- Research and development
