Introduction
Moisture Mapping plays a vital role in monitoring and managing wood moisture levels. This process involves determining the moisture content of wood to prevent decay, structural damage, and other moisture-related issues.
Wood Moisture Content
Wood moisture content is expressed as a percentage of the oven-dry weight of the wood. When wood is freshly cut, it contains a high moisture content, which gradually decreases as it dries.
Can Wood Contain Over 100% Moisture Content?
Yes, wood can contain over 100% moisture content. This occurs when the wood absorbs more water than its oven-dry weight. This condition is known as “above fiber saturation point (FSP).” At FSP, the wood’s cell walls are fully saturated with water, and the excess moisture is present in the cell cavities.
Implications of Over 100% Moisture Content
Wood with moisture content over 100% is highly susceptible to decay, mold, and other moisture-related problems. This is because the excess moisture provides an ideal environment for microorganisms to thrive.
Conclusion
Moisture Mapping is essential for maintaining proper wood moisture levels. Understanding the concept of wood moisture content and the possibility of over 100% moisture content is crucial for effective moisture management and preserving wood’s structural integrity.
