Moisture Readings for Resilient Buildings

What should moisture readings be for internal walls?

Accurate moisture readings are crucial for ensuring the longevity and resilience of buildings. For internal walls, optimal moisture content is essential to prevent structural damage, mold growth, and health hazards.

Moisture Content Guidelines

The acceptable range of moisture content for internal walls depends on the type of material used:

• Gypsum wallboard: 6-12%
• Concrete block: 4-8%
• Brick: 4-8%
• Wood studs: 6-12%

Consequences of Excessive Moisture

• Structural damage: Excess moisture can weaken walls, leading to cracks and other structural issues.
• Mold growth: High moisture levels create an ideal environment for mold to thrive, posing health risks.
• Health hazards: Mold and excessive humidity can cause respiratory problems, allergies, and other health concerns.
• Reduced energy efficiency: Moist walls act as a thermal bridge, allowing heat to escape and increasing energy costs.

Monitoring Moisture Levels

Regular moisture readings are essential to monitor the health of internal walls. This involves using a moisture meter to measure the moisture content of the wall at various depths.

Expert Guidance

If moisture readings exceed the recommended levels, it is advisable to consult an experienced professional for further investigation and resolution. They can determine the source of the moisture and recommend appropriate measures to address it effectively.

By maintaining optimal moisture levels in internal walls, building owners can ensure the long-term integrity, health, and energy efficiency of their structures.
