Helical piles in Olathe, Kansas

Clay is the main reason Kansas homeowners call a foundation contractor. The Kansas Geological Survey describes soils high in montmorillonite clay that shrink when dry and swell when wet. Eastern Kansas, especially the Kansas City suburbs, sees basement and slab settlement tied to these soils.

Frost depth varies by city. A compiled frost-depth reference citing local codes lists 36 inches for Overland Park and Kansas City, Kansas, and your Olathe building office has the official figure. Helical piers usually go deeper to reach competent soil, and the guide notes that on expansive clay the design should consider uplift on the shaft.
