Moisture Mapping and Detection Methods

The process of creating a graphical representation of moisture levels and patterns within a building envelope, structure, or material is known as moisture mapping. It provides valuable insights into the location and extent of moisture intrusion, enabling targeted interventions and measures to address moisture issues more effectively.

How Does Moisture Mapping Work?

Moisture mapping involves the use of specialized equipment and techniques to detect and measure moisture presence and distribution.

• Infrared cameras: Infrared cameras emit heat radiation, which is reflected back by surfaces. Moisture affects the thermal reflection, and thus, areas with moisture retention appear cooler in the thermal images captured by these cameras.
• Moisture meters: Moisture meters use electrical signals to determine the moisture content of materials. By inserting probes into the surface or using non-invasive methods, these meters provide quantitative readings of moisture levels.
• Hygrometers: Hygrometers measure the relative humidity of the air. By measuring moisture content at specific locations, hygrometric data helps establish the moisture source and migration patterns.
