Restoring Equity Below Ground: How Davenport Homeowners Solved Deep Foundation Settlement

In Davenport, IA, a local homeowner noticed telltale signs of foundation settlement: sticking doors, sloped floors, and cracked drywall. Recognizing the threat to their home’s safety and resale value, they turned to MidAmerica Basement Systems.

Eastern Iowa’s expansive clay soil shrinks during droughts and swells with rain. Over time, this constant movement washes out subgrade support, causing heavy concrete footings to sink unevenly.

To solve the root problem, System Design Specialist Rob Chismark engineered a permanent plan using an industrial-grade Helical Pier System. Instead of relying on weak surface soil, helical piers transfer the building's weight deep underground to dense, stable strata.

Foreman Ian Carnithan and technicians David, Gio, and Markell excavated small access pits to expose the footings. Using high-torque hydraulic drivers, they screwed heavy-gauge steel piers deep into the earth past the unstable clay layer, monitoring torque in real time to verify weight capacity.

Once anchored, heavy-duty steel brackets were secured under the footings. Using a manifold hydraulic jack system, the crew transferred the home's weight onto the steel piers, stabilizing the foundation and lifting the structure back toward its original level position.

The results were immediate: interior doors realigned, sloped floors stabilized, and the excavation pits were cleanly backfilled. By bypassing the unstable soil, the homeowner permanently protected their investment and regained complete peace of mind.
