Raytown

Helical piles in Raytown, Missouri

Raytown is in the Kansas City area, in a state the Missouri Department of Natural Resources says has about 16,000 identified sinkholes. Add clay soils that shrink and swell and winters cold enough to heave shallow footings, and many homeowners end up looking for deeper support.

Missouri has no single statewide frost depth for site-built homes. Kansas City and St. Louis area codes commonly call for 30 to 36 inches, so confirm the number with your building department. Helical piers install with compact equipment and can carry load right away, which helps in older neighborhoods where brick homes sit close together.

Questions to put to any installer:

• Will a licensed engineer design the piles for local clay and possible karst, and can you see the calculations?
• What installation torque will be logged for each pile, and will you receive the torque records?
• What shaft diameter and wall thickness are proposed, and is the steel galvanized in clay soil?
• Who pulls the permit with the City of Raytown, and what does the written warranty cover?
