St. Louis sits on expansive clay soil that swells when saturated and shrinks during dry periods, creating foundation movement that cracks basement walls and separates floor joints. After spring storms that saturate the ground, hydrostatic pressure forces water through these foundation cracks and up through floor drains. Insurance adjusters frequently dispute whether this water intrusion constitutes covered sudden damage or excluded groundwater seepage. Proper documentation requires showing the water source, entry point, and rapid accumulation that proves sudden failure rather than gradual infiltration. Homes near the River Des Peres and in flood-prone areas like Lemay face additional scrutiny because adjusters assume any basement water comes from external sources that policies exclude.
