Helical pile installer for Overland Park, Kansas: Power Lift Foundation Systems, with notes on shrink-swell clay, 36-inch frost depth and costs.
Overland Park is in the Kansas City suburbs, where basement and slab settlement tied to expansive clay is common. The Kansas Geological Survey describes soils high in montmorillonite clay that shrink when dry and swell when wet, and helical piers can carry a house down to more stable soil.
A compiled frost-depth reference citing local codes lists 36 inches for Overland Park and 24 inches for Wichita. Your building department sets the requirement, and helical piers usually go deeper to reach competent soil. On expansive clay, the design should also consider uplift on the pier shaft.
