Moisture Mapping A Comprehensive Guide to Acceptable Moisture Levels

Moisture mapping is a crucial technique in building diagnostics to evaluate the moisture content within building materials and structures. It involves measuring the moisture levels at various locations to identify potential moisture intrusion, leaks, or condensation issues.

Acceptable Moisture Levels

Acceptable moisture levels in building materials vary depending on the material type, environmental conditions, and building use. High moisture levels can lead to structural damage, mold growth, and poor indoor air quality.

What Should Moisture Readings Be for Internal Walls?

  • Wood studs: 10-15% moisture content (MC)
  • Drywall: Up to 15% MC
  • Plaster: Up to 10% MC

It's important to note that these values are guidelines, and the actual acceptable moisture levels may be influenced by specific building conditions and climate factors. If moisture readings exceed these levels, further investigation is warranted to identify and address the source of moisture intrusion.
