Leaky pipes beneath or near your foundation can erode soil over time:
- Regularly inspect plumbing systems for leaks.

Unexpected weight from renovations or heavy equipment may compress the ground below excessively.
6. Natural Disasters
Earthquakes or floods can cause sudden shifts in ground stability:
- Check local geological reports to understand risks specific to your area.
