### Wood Moisture Content: Understanding the Basics

Moisture mapping involves determining the moisture content of wood, a crucial factor that can significantly impact its properties and performance. Moisture content refers to the amount of water present within wooden structures or products, typically expressed as a percentage of their dry weight.

### Why is Moisture in Wood Bad?

Excessive moisture in wood can lead to various detrimental consequences:

– **Dimensional instability:** Wood tends to expand when moisture content increases and contract when it decreases. This can cause warping, cupping, or other distortions, compromising the structural integrity and aesthetic appearance of wooden components.
– **Fungal decay:** High moisture levels provide a favorable environment for wood-destroying fungi to thrive. Fungal growth can weaken wood, leading to rot, decay, and premature structural failure.
– **Insect infestation:** Moisture-rich wood attracts insects such as termites and woodworms, which can further damage wooden structures by boring holes and creating galleries.
– **Loss of strength and stiffness:** Excess moisture can reduce the mechanical strength and stiffness of wood, making it more susceptible to cracking, bending, or buckling under stress or load.
– **Conductivity:** Wet wood becomes more conductive to electricity, increasing the risk of electrical hazards and potential fires.
