Introduction

Moisture Mapping is a non-destructive method used to detect and map moisture in a building or structure. This technique is particularly valuable for identifying hidden moisture problems that may not be visible to the naked eye. By using specialized equipment, moisture mapping allows for a comprehensive understanding of the moisture distribution, helping to pinpoint areas that require further investigation or repair.

Moisture Mapping and Detection Methods

Infrared Thermography

• Uses an infrared camera to detect temperature differences on a surface. Moisture can be identified by its lower temperature, as it absorbs and retains heat less efficiently than dry materials.

Electrical Impedance Scanning

• Measures changes in electrical current as it passes through a material. Moisture increases the electrical impedance, which can be detected and mapped.

Capacitive Sensing

• Detects changes in capacitance caused by the presence of moisture. Capacitance increases with moisture content, providing a quantitative measurement.

Neutron Backscattering

• Uses neutron bombardment to detect hydrogen, which is a component of water. Higher moisture levels result in higher neutron backscattering counts.

How to Check for Moisture Under a House?

Visual Inspection

• Look for signs of moisture damage, such as mold, mildew, or water stains. Check for areas with peeling paint or wallpaper.

Moisture Meter

• Use a moisture meter to measure the moisture content of floors, walls, or other building materials. A high moisture content may indicate a leak or other moisture problem.

Thermal Imaging

• Use a thermal imaging camera to detect cold spots or areas with higher moisture content. These areas may be indicative of hidden moisture issues.

By utilizing these detection methods, moisture mapping provides a valuable tool for moisture detection and prevention, ensuring a healthy and comfortable living environment.
