Moisture Mapping Exploring Wood Moisture Content and Its Limits

Wood Moisture Content

Moisture content refers to the amount of water present within the pores and fibers of wood. It plays a critical role in the physical and mechanical properties of wood. The moisture content of wood is usually expressed as a percentage, calculated by comparing the weight of the water contained in the wood to the weight of the dry wood.

Can Wood Contain Over 100% Moisture Content?

It is possible for wood to contain over 100% moisture content. This condition occurs when the wood is saturated with water, and the water weight exceeds the weight of the wood itself. In such cases, the wood is referred to as being “fully saturated” or “waterlogged.”

Consequences of Excessive Moisture Content

  • Reduced strength and stiffness
  • Increased susceptibility to rot and decay
  • Warpage and distortion
  • Impaired drying performance
  • Increased electrical conductivity
  • Impeded machining operations
