Moisture Mapping A Guide to Moisture Detection Methods

Moisture mapping is a highly effective method for detecting and assessing moisture levels within a building envelope. With its ability to precisely locate moisture intrusions, moisture mapping provides building professionals with invaluable insights into the health and integrity of a structure. Utilizing specialized equipment and techniques, moisture mapping offers a comprehensive analysis, minimizing potential risks and ensuring the longevity of the building.

How Does Moisture Mapping Work?

Moisture mapping utilizes a range of technologies to detect and measure moisture levels within building materials and surfaces. Common methods include:

• **Electrical impedance tomography (EIT)** employs an electrical current to assess moisture distribution, generating an image that represents moisture levels.
• **Microwave imaging** employs high-frequency electromagnetic waves to penetrate building materials, providing a non-invasive means of detecting moisture.
• **Thermal imaging** utilizes infrared cameras to visualize temperature differences, which can indicate areas of high moisture content.
• **Ground-penetrating radar (GPR)** sends electromagnetic pulses through the ground to detect underground moisture and water infiltration.
