Moisture Mapping Understanding Acceptable Moisture Levels

Acceptable Moisture Levels

Moisture Mapping is a critical tool for identifying and addressing moisture issues within a building. Establishing acceptable moisture levels is essential to prevent damage, maintain a healthy indoor environment, and ensure the longevity of the structure.

What is an Acceptable Damp Reading?

Acceptable damp readings can vary depending on several factors, including:

*

  • Building materials
  • Ambient temperature and humidity
  • Location of measurement

Generally, acceptable moisture readings for wooden structures range between 6-12%. Readings below 6% indicate dryness, which can lead to shrinkage and cracking; readings above 12% suggest excess moisture that can contribute to mold, rot, and structural damage.

Concrete and masonry materials have higher acceptable moisture levels due to their porous nature. Readings for concrete typically range between 10-15%, while masonry can tolerate up to 20%.

It is crucial to note that these readings serve as guidelines, and factors such as building age, construction methods, and local climate conditions may necessitate adjustments.
