Moisture Mapping Uncovering Hidden Dampness in Walls

Moisture Mapping is a crucial diagnostic tool for detecting and assessing the extent of dampness in walls. Dampness can be caused by a variety of factors, such as leaks, condensation, and water penetration. It can lead to structural damage, mold growth, and deterioration of indoor air quality.

Methods of Moisture Mapping

  • Infrared Imaging: uses infrared cameras to detect temperature differences caused by dampness.
  • Electrical Moisture Meter: measures the electrical conductivity of the wall, which increases in the presence of moisture.
  • Pin and Probe: involves drilling small holes in the wall to insert moisture-sensitive pins or probes.
  • Surface Resistance Meter: measures the resistance of the wall surface to the flow of electricity.
  • Conductive Grid Method: employs a grid of conductive strips attached to the wall surface, which detect changes in conductivity due to moisture.

How to Detect Dampness in a Wall

  • Visual Inspection: Look for signs of dampness, such as peeling paint, water stains, or efflorescence (white powdery deposits).
  • Touch Test: Feel the wall for coldness or dampness.
  • Moisture Meter Reading: Use an electrical moisture meter to measure moisture levels.
  • Moisture Mapping: Hire a professional to perform a thorough moisture mapping survey using appropriate detection methods.
