Understanding Moisture Content in Building Materials

Moisture content is a crucial factor that affects the durability, energy efficiency, and healthiness of a building. It is the amount of water present in building materials, expressed as a percentage of the material's dry weight. Understanding the moisture content of building materials is essential for maintaining a healthy and comfortable indoor environment.

What Should Moisture Readings Be for Internal Walls?

The ideal moisture content for internal walls varies slightly depending on the material and climate. Generally, the following ranges are considered acceptable:

  • Gypsum plasterboard: 6-12%
  • Concrete: 4-8%
  • Bricks: 5-10%

Higher moisture content levels can indicate potential issues such as water damage, mold growth, or structural instability. If moisture readings exceed these ranges, it is advisable to investigate the source of the excess moisture and take appropriate measures to rectify the situation.
