Moisture Mapping Delving into Wood Moisture Content

Wood Moisture Content: A Comprehensive Overview

Wood moisture content plays a crucial role in various aspects of wood-related industries. The amount of moisture present within wood significantly impacts its physical and mechanical properties.

Can Wood Contain Over 100% Moisture Content?

Typically, wood moisture content is expressed as a percentage of the weight of the oven-dry wood. The moisture content of freshly cut wood can vary greatly depending on the species, but it generally ranges from 30% to 100%. While it is not common, under exceptional circumstances, wood can contain over 100% moisture content. This condition is known as "waterlogged" or "saturated" wood and occurs when the wood absorbs water beyond its maximum capacity. This can happen when wood is submerged in water for extended periods or exposed to severe weather conditions, such as flooding.

Consequences of Over 100% Moisture Content

Excessive moisture content in wood can lead to several detrimental effects:

• Decay and rot: The presence of moisture provides an ideal environment for fungi and other microorganisms to thrive, leading to the deterioration of wood.
• Warping and shrinkage: As wood dries, it shrinks and warps due to uneven moisture loss. This can result in damage to structures or finished wood products.
• Reduced strength and durability: High moisture content weakens the wood's fibers, compromising its structural integrity.
