How helical piers work
Each pier is advanced into the soil like a large threaded anchor, with capacity verified by installation torque as it goes. Because the pier is anchored rather than resting on resistance alone, it resists both settlement and upward soil movement during moisture-rich seasons. Installation is precise, low-vibration, and suited to limited-access sites.
Where helical piers fit at homes
Heave-prone conditions.
Anchored resistance to upward soil movement in heavy, moisture-rich clay.
Lighter structures.
Additions, porches, and homes where torque-verified capacity fits the load.
Limited-access and sloped lots.
Compact installation equipment reaches where larger rigs cannot.
Tension applications.
The same helical family provides tieback anchors for retaining walls.

Frequently asked questions
They are screwed into the soil rather than pressed or poured, with capacity verified by installation torque, and they resist upward heave as well as settlement.
The inspection findings decide: soil behavior, structure weight, and access all factor in, and sometimes the honest answer is that no pier is needed.
