Moisture Monitoring in Flooring and Wall Coverings

Accurate moisture readings are crucial for ensuring the durability and integrity of flooring and wall coverings. Excessive moisture can lead to structural damage, mold growth, and costly repairs.

What Should Moisture Readings Be for Internal Walls?

Optimal moisture readings for internal walls vary depending on the wall's composition. Ideally, readings should fall within the following ranges:

  • Concrete walls: 4 - 7% (calcium chloride test method)
  • Plaster walls: 1 - 5% (gravimetric test method)
  • Drywall walls: 0 - 16% (gypsum moisture probe)

Consequences of Excessive Moisture

Excessive moisture in internal walls can result in several adverse consequences:

  • Structural damage: Moisture can weaken wall materials, leading to cracking, bowing, and even collapse.
  • Mold growth: Moisture provides an ideal environment for mold to thrive, posing health risks and damaging the wall's integrity.
  • Reduced insulation: Wet walls significantly reduce insulation effectiveness, increasing energy costs.
  • Efflorescence: Excess moisture can leach salts to the wall's surface, forming unsightly white deposits.
  • Paint failure: Moisture can cause paint to blister, peel, or discolor.

Importance of Regular Monitoring

Regular moisture monitoring is essential to detect and mitigate potential moisture issues promptly. It allows for early intervention, preventing costly repairs and ensuring the longevity of flooring and wall coverings.
