Moisture Mapping and Detection Methods

Moisture Mapping

Moisture mapping refers to a non-destructive method utilized for locating and assessing moisture levels within a structure or surface. It plays a crucial role in identifying and managing moisture-related issues impacting buildings, roofs, and other assets.

Detection Methods

Infrared Thermography

This technique employs a specialized camera to detect temperature variations across a surface. Moisture tends to absorb and retain heat differently, creating a thermal contrast that can be visualized and analyzed.

Microwave Scanning

Microwave pulses are transmitted into the surface, and the time and intensity of their return signals are used to deduce the presence and distribution of moisture.

Electrical Impedance Tomography

This method involves injecting electrical current into the surface and measuring the impedance (resistance) changes caused by moisture content.

Ultrasonic Scanning

Ultrasonic waves are emitted into the surface, and their propagation speed and attenuation can be used to determine the location and extent of moisture.

How Does Moisture Mapping Work?

Moisture mapping typically involves the following steps:

• Site Inspection: A trained professional conducts a visual inspection to identify potential sources of moisture, such as leaks or water damage.
• Measurement: The appropriate detection method is selected and used to measure moisture levels at strategic locations.
• Data Analysis: The collected data is analyzed to create a moisture map, which depicts the distribution and severity of moisture infiltration.
• Report Generation: A detailed report summarizing the findings, including the location, extent, and potential causes of moisture issues, is provided.
