Waterproofing and Moisture Barriers

Moisture Readings for Internal Walls

What should moisture readings be for internal walls?

For optimal building performance and occupant health, moisture levels in internal walls should be carefully monitored and controlled. The presence of excessive moisture can lead to a range of issues, including structural damage, mold growth, and poor indoor air quality. Therefore, it is essential to establish and maintain appropriate moisture readings for internal walls.

The acceptable range of moisture readings for internal walls can vary depending on the specific materials used in the wall’s construction. However, as a general guideline, the following moisture levels are considered acceptable:

  • Wood walls: Moisture content below 16%
  • Masonry walls: Moisture content below 25%
  • Plaster walls: Moisture content below 30%

Moisture readings above these levels may indicate the presence of excessive moisture, which can lead to deterioration of wall materials, mold growth, and other problems. It is important to consult with qualified professionals to determine the appropriate moisture levels for specific internal wall materials.

Regularly monitoring moisture readings in internal walls is crucial for detecting and addressing any potential moisture issues promptly. By maintaining appropriate moisture levels, homeowners and building managers can help ensure the longevity and well-being of their structures.
