Flooded basements is such a common problem in some midwest markets that I did a whole podcast on the subject. 99% of water intrusion is due to improper drainage and soil grading and can be mitigated by having properly functioning gutters and downspouts and grading the soil away from the foundation.

Ongoing leaks can undermine the soil below your building which can cause catastrophic issues.
