In a foundation inspection, what is a key indicator of potential settlement?

Cracks in the foundation walls are a key indicator of potential settlement because they often signal that the structure is experiencing shifts or movement due to changes in soil conditions, moisture content, or improper drainage. Foundation settlement typically occurs when the soil beneath the foundation compresses or shifts, which can lead to stress on the walls and results in cracking. The patterns, widths, and locations of these cracks can provide insight into the extent of the settlement and whether it poses a structural concern.

Moisture stains may suggest water infiltration issues, which can indirectly lead to problems but are not direct indicators of settlement. Crumbling concrete might indicate age or poor material quality but does not specifically point to settlement. Uneven flooring can suggest some structural issues related to settlement but is more of a symptom rather than a direct indication compared to visible cracks in the foundation walls. Therefore, monitoring for cracks is essential in assessing the health of a structure's foundation and potential settlement issues.
