Moisture Mapping and Detection Methods

What is Moisture Mapping?

Moisture mapping is a process of identifying and locating areas of moisture penetration in a building or structure. It is a valuable tool for diagnosing and resolving moisture-related issues such as mold growth or structural damage.

Detection Methods

Invasive Methods

*

  • Moisture meters: Handheld devices that measure moisture content in materials.
  • *

  • Drill-and-fill probes: Holes are drilled into the wall, and probes are inserted to measure moisture levels.
  • *

  • Infrared thermography: An infrared camera is used to detect differences in temperature that may indicate moisture.
  • Non-Invasive Methods

    *

  • Relative humidity sensors: Placed in the air to measure moisture levels.
  • *

  • Condensation meters: Identify areas where condensation is likely to occur by measuring surface temperature and relative humidity.

    Visual Inspection

    *

  • Look for stains, discoloration, or peeling paint.
  • *

  • Check for cracks or holes that could allow moisture to enter.
  • *

  • Feel for dampness or coolness on the surface.
  • Moisture Meters

    *

  • Use a moisture meter to measure moisture content in the wall.
  • *

  • Insert the probes into the wall at different depths to get an accurate reading.
  • *

  • Compare the readings to manufacturer’s specifications for acceptable moisture levels.
  • Other Methods

    *

  • Infrared thermography: Use an infrared camera to detect temperature differences in the wall.
  • *

  • Relative humidity sensors: Place sensors near the wall to monitor humidity levels.
  • *

  • Condensation meters: Use condensation meters to identify areas of potential condensation on the wall surface.
