Moisture Mapping: What is it?

Moisture Mapping is an essential part of any Building Sciences or Indoor Air Quality (IAQ) project. Building Moisture occurs due to a variety of factors such as flooding, leaks, condensation, and water damage. These can lead to many problems, including mold, wood rot, and structural damage if left unchecked. Moisture Mapping can help identify moisture issues quickly and accurately so that they can be addressed before they cause major problems. Moisture Mapping involves using specialized equipment to measure the moisture content of various materials including wood, drywall, and concrete. Moisture is measured using Moisture Meters, the data collected is then used to create a map showing the location and extent of moisture issues.

Moisture Monitoring Equipment

There are a variety of different moisture monitoring equipment available, each with its own advantages and disadvantages. Some of the most common types of moisture meters include:

• Pin-type moisture meters: These meters have two pins that are inserted into the material being tested. They measure the electrical resistance between the pins, which is affected by the moisture content of the material.
• Capacitance moisture meters: These meters use a capacitor to measure the dielectric constant of the material being tested. The dielectric constant is affected by the moisture content of the material.
• Infrared moisture meters: These meters use infrared radiation to measure the temperature of the material being tested. The temperature of the material is affected by its moisture content.

The type of moisture meter that is best for a particular application will depend on the material being tested, the accuracy required, and the budget. Different types of Moisture Meters are better suited for different materials. For instance, Pin-type meters are more accurate on softer materials like wood while Capacitance meters work better on harder materials like concrete. High-frequency meters are well-suited for materials which do not react well to having probes stuck into them, such as drywall or fabrics.

Do moisture meters really work?

Yes, moisture meters can be an effective tool for detecting moisture in materials. However, it is important to use them correctly and to understand their limitations. Moisture meters can be affected by a number of factors, including the type of material being tested, the temperature and humidity of the environment, and the skill of the person using the meter. It is also important to remember that moisture meters only measure the moisture content of the surface of the material. They cannot detect moisture that is hidden within the material.

Moisture Mapping is a valuable tool for identifying moisture issues in buildings. By using the right equipment and following the proper procedures, you can get accurate and reliable results.
