What causes basement leaks in St. Louis homes?

Basement leaks are a common problem in the St. Louis area due to our expansive clay rich soil and heavy seasonal rainfall. As the ground expands and contracts, it puts pressure on foundation walls and allows water to find its way inside. Common causes of leaks include foundation cracks, failed window wells, poor drainage, or hydrostatic pressure pushing water through basement walls and floors.
