Why Harrisonville Foundations Develop Problems

Cass County sits on the same Wymore-Ladoga clay that defines the Kansas City metro. The clay swells dramatically when saturated and shrinks when dry. Over the life of a Harrisonville home, the foundation goes through 40 or more shrink-swell cycles, and every cycle adds stress to the concrete, block, or stone holding up the house.

Harrisonville’s mix of housing stock means we work on a wide range of foundation types. Older homes around the historic Harrisonville Courthouse Square and the streets near Allen Park often have stone, brick, or block foundations from the late 1800s or early 1900s. These are usually structurally sound and need stabilization rather than replacement. Newer subdivisions on the outskirts of town, including the developments near North Cass High School and along the 71 corridor, see first-decade settlement as fill soil around new foundations consolidates.

We had purchased a home at the beginning of the year and noticed some deformities with our foundation. We called Foundation 1 and they promptly sent out their evaluator, Cassell, who thoroughly inspected the foundation and gave us peace of mind that the deformities are normal and easy patch jobs. Although there was no repairs to be made, we felt comfortable and at ease with the thorough inspection and explanation. We are glad to have their information and will use them if needed in the future and will recommend them to everyone!
