Moisture Measurement Interpretation

How to Do a Moisture Test on Walls?

Moisture testing on walls is conducted to check if the walls have excessive moisture content, which can indicate potential moisture issues. These tests are conducted by drilling through the wall to reach the interior, where a moisture meter is inserted to measure the moisture content.

The results of the moisture test help in determining the extent of moisture damage, if present. By understanding how to interpret the results of a moisture measurement, you can better make informed decisions regarding the necessary repairs and/or further mitigation measures.

Interpreting Moisture Measurement Results

The moisture content of the wall is determined by the moisture meter used, which measures the electrical resistance between two probes. The higher the resistance, the lower the moisture content, and vice versa.

The following general guidelines can help you interpret the results of a moisture measurement:

  • Acceptable Moisture Level: Less than 15% moisture content is generally considered acceptable for most building materials.
  • Moderate Moisture Level: Between 15% and 25% moisture content indicates the presence of moisture, but it may not necessarily be a cause for concern.
  • High Moisture Level: Moisture content above 25% is considered high and can lead to mold growth and other moisture-related issues.
  • Excessive Moisture Level: Moisture content above 30% is excessive and requires immediate attention to prevent further damage to the building.

It’s important to note that these are general guidelines and the actual interpretation may vary based on the type of building material and the specific conditions of the building.

If you have concerns about moisture damage in your walls, it’s recommended to consult with a qualified professional for further assessment and appropriate action. They can interpret the moisture measurement results accurately and determine if there is a need for further investigation or repair work.
