Helical piles in Blaine, Minnesota

Blaine homeowners build decks, porches and pergolas that must resist frost heave. Minnesota's frost rule is one of the deepest in the country: Minnesota Rules 1303.1600 sets minimum footing depth at 3-1/2 feet in southern Zone II and five feet in northern Zone I, unless an engineer determines otherwise.

Helical piers bear below the frost zone, so seasonal freezing near the surface does not lift them the way it can lift a shallow footing. The engineer also checks the shaft and bracket for frost-related loads. Typical Twin Cities area uses include additions, garage expansions and solar arrays.

Questions to put to any installer in Blaine:

• Is the design engineered for my site conditions, or based on a standard pier schedule?
• How do you verify capacity during installation, and can I see the torque logs?
• What is the shaft size, and what corrosion protection does it carry?
• Which permits does Blaine require for this work, and who is responsible for them?

Get written quotes from at least two companies and ask each to explain how the pier count and depth were determined.
