Helical Pier Underpinning
Helical Pier Underpinning for Additions and Light Structures
Helical piers thread into stable strata under measured torque, making them ideal where upper soil profiles are unstable or a hydraulic push pier has no structural weight to react against.

When helical beats push piering
Push piers rely on the weight of the structure to drive them. Light structures — sunrooms, three-season rooms, porches, garages and decks — do not weigh enough, so the pier stalls before reaching competent soil.
Helical piers solve that. They are torqued in, and installation torque correlates directly to load capacity, so each pier is verified as it goes in rather than assumed.
Where we see it most in Central Indiana
Post-2000 subdivisions across Fishers, Noblesville and Westfield were often graded over former agricultural drainage basins with deep, poorly compacted fill. Helical shafts pass straight through that fill into undisturbed till.
On Zionsville's Eagle Creek ravine lots, helical piers also resist the downslope creep that plagues shallow footings.
