What does the presence of efflorescence on basement walls indicate?

• A. High humidity levels
• B. Moisture penetration and water intrusion
• C. Poor ventilation
• D. Structural damage

Answer: (B)

The presence of efflorescence on basement walls indicates moisture penetration and water intrusion. Efflorescence is a white, powdery substance that appears on surfaces, such as masonry or concrete, when water evaporates and leaves behind soluble salts. This typically occurs when water seeps through walls due to issues like poor drainage, leaks, or high groundwater levels. When you see efflorescence, it serves as a visible sign that water is making its way through the material, which can lead to further issues such as mold growth or deterioration of the structural components if not addressed. Addressing the moisture problem is crucial to preventing damage and maintaining a healthy living environment.
