Moisture mapping is a non-invasive technique used to identify areas of excessive moisture within a building structure. It involves using specialized equipment to measure the moisture content of various building materials, such as walls, floors, and ceilings.
The acceptable moisture levels for building materials vary depending on the material type and the intended use of the space. Generally, moisture levels below 15% are considered acceptable for most interior building materials.
For internal walls, moisture readings should typically be below 15%. However, it is important to note that some variability is normal due to factors such as temperature, humidity, and the presence of moisture sources (e.g., bathrooms or kitchens).
Elevated moisture readings in internal walls can indicate a potential problem, such as a water leak or inadequate ventilation. In these cases, further investigation is recommended to determine the source of the moisture and address it appropriately.
