Moisture Mapping is a crucial technique used to identify areas of moisture accumulation within a building or structure. It involves using specialized equipment to measure the moisture content of various materials, including drywall, plaster, wood, and concrete.

Acceptable Moisture Levels

Moisture Mapping allows building professionals to determine if moisture levels are within acceptable ranges, preventing potential problems such as mold growth, structural damage, and poor indoor air quality.

• Drywall: Acceptable moisture content ranges from 5% to 12%
• Plaster: Acceptable moisture content ranges from 4% to 10%
• Wood: Acceptable moisture content ranges from 8% to 12%
• Concrete: Acceptable moisture content ranges from 2% to 5%

What is a Normal Moisture Reading for Drywall?

For drywall, a normal moisture reading typically falls between 5% and 12%. Readings below 5% indicate very dry conditions, while readings above 12% suggest elevated moisture levels that may require further investigation and remediation efforts.

Moisture Mapping is a reliable and effective method for assessing moisture levels and identifying potential moisture problems. By understanding acceptable moisture levels and interpreting drywall moisture readings, building professionals can ensure the safety and longevity of structures.
