Moisture penetration through the foundation wall can cause the foundation to flake off on the interior. This condition is called:

The condition described, where moisture penetration causes the foundation to flake off on the interior, is known as spalling. Spalling occurs when water infiltrates the concrete, leading to deterioration and the outward flaking or chipping of the material. This process can be exacerbated by freeze-thaw cycles, where trapped water expands when frozen, causing cracks and further damage.

Monitoring and addressing spalling is essential because it can compromise the structural integrity of the foundation over time. Identifying moisture intrusion early can help prevent more extensive damage and costly repairs.

Other conditions like honeycombing and cold joints refer to different issues related to concrete quality and formation, whereas efflorescence describes crystalline deposits of salts on the surface of masonry or concrete, which indicates moisture presence but does not involve flaking material.
