Helical piles in Winfield, Missouri

Soil and weather combine in Missouri to push builders toward deeper foundations. Clay soils shrink and swell, winters can heave shallow footings, and the state sits in a karst region with sinkholes mapped by the Missouri Department of Natural Resources. Helical piers install with compact equipment, can be tested by torque as they go in, and carry load right away.

There is no single statewide residential frost depth for site-built homes. For manufactured homes, the Missouri Public Service Commission's frost depth map ranges from 12 inches south of I-44 to 25 inches north of Highway 36, and local jurisdictions may require more. Typical uses include deck and porch footings, additions, agricultural buildings and ground-mount solar.

• What frost depth does the local building office require for my lot?
• Is the pile you propose a round or square shaft, and why?
• Will you provide torque logs for every pier?
• Who pulls the permit, and what does the warranty cover?
