Wood Moisture Content: An Overview
Wood exhibits a dynamic relationship with moisture, affecting its properties and stability. Moisture content refers to the amount of water present in the wood relative to its dry weight. Accurate measurement of moisture content is crucial for various applications, including construction, forestry, and manufacturing.
Can Wood Contain over 100% Moisture Content?
Contrary to common belief, it is possible for wood to hold moisture content exceeding 100%. This phenomenon occurs when the wood’s weight increases due to absorbed water so that its moisture content surpasses its dry weight. This condition is referred to as “over-saturated” wood.
Factors Contributing to Over-saturated Wood
- Prolonged immersion or exposure to water, as in flooding or waterlogging
- High humidity environments
- Water-based treatments or preservatives
Excessive moisture content compromises wood’s structural stability, increases its susceptibility to rot and decay, and can diminish its strength and performance.
