Maple Grove

Helical piles in Maple Grove, Minnesota

Maple Grove homeowners are building in suburban lots where soil can include fill, clay and silt over glacial till. The state guide notes that the flat Red River Valley is capped by 5 to 60 feet of fine silt, a reminder of how variable Minnesota ground can be from one region to the next.

For Maple Grove projects, the practical issue is frost. Pile tops must sit below the frost line, and the helix plates bear deeper in stable soil, so seasonal freezing near the surface does not lift the pier the way it can lift a shallow footing. Lake and cabin foundations, additions and deck footings are typical uses.

Costs and what to ask

Nationally, helical piers typically run about $2,000 to $4,000 each installed, with an average near $3,000, according to Foundation Repair HQ, which notes that hand-digging around landscaping can add $200 to $500 per pier. Expect the Maple Grove total to track pier count, depth and access more than any flat rate. Read our helical pier cost guide before comparing bids. Questions worth asking any installer:

• Who is the engineer of record, and how was the pile depth chosen for the Maple Grove lot?
• Are torque readings recorded as each pile is driven, and are they given to you at closeout?
• Is the steel galvanized, and what shaft size and helix plates are specified?
• Does the quote include permits in Maple Grove and a written warranty on the work?
