If your home shows signs of settling, like cracks in walls, uneven floors, or sticking doors, helical piers may be the solution. These steel foundation supports are designed to reach stable soil deep below the surface, providing a permanent fix for weak or shifting ground.
In this guide, we’ll explain what helical piers are, how they work, and why they’re one of the most effective methods for long-term foundation stabilization.

What Are Helical Piers?
Helical piers, sometimes called screw piles, are long steel shafts with helix-shaped plates welded to the bottom. These “screw-like” blades allow the piers to be twisted deep into stable soil beneath your home. Once installed, they transfer the weight of your house to solid ground far below the shifting or weak surface soils.
Unlike concrete underpinning, which requires heavy excavation, helical piers are installed with specialized hydraulic equipment and cause minimal disruption to your property. They’re commonly used for both residential and commercial projects to stabilize foundations and prevent further settlement.
In simple terms: helical piers act like giant steel anchors, securing your foundation to stable soil so your home stays level and supported.
How Do Helical Piers Work?
Helical piers provide stability by transferring your home’s weight to deep, load-bearing soil. The process is precise and efficient, making them a trusted solution for many types of foundation repair.
Bottom line: helical piers create a strong, lasting connection between your foundation and stable ground, keeping your home safe for decades to come.
Cracks in Walls or Floors
Diagonal or stair-step cracks in drywall, brick, or basement floors often point to foundation settlement that needs immediate attention.
Sticking Doors and Windows
If doors and windows no longer open or close properly, shifting soil may be causing your foundation to tilt or sink unevenly.
Uneven or Sloping Floors
Floors that slope, bounce, or feel uneven can signal that your foundation is no longer properly supporting your home.
Gaps Around Trim or Cabinets
When your foundation moves, it can pull apart finishes inside your home. Gaps between walls, ceilings, or cabinets often reveal underlying settlement.
Visible Foundation Movement
If you notice sections of your foundation visibly sinking, separating, or pulling away from the structure, helical piers may be required to stabilize and restore support.
In short: if your home feels like it’s shifting, sinking, or pulling apart, it’s time to consider helical piers as a long-term foundation repair solution.
Benefits of Helical Piers for Foundation Repair
Homeowners and contractors trust helical piers because they deliver reliable, long-term results with minimal hassle. Here’s why they’re such a popular choice for foundation repair solutions:
Bottom line: helical piers combine speed, strength, and long-term reliability, making them one of the best options for stabilizing a settling foundation.
Helical Piers vs. Other Foundation Repair Methods
Not all foundation repair methods are the same. Here’s how helical piers compare to other common options:
| METHOD | HOW IT WORKS | BEST FOR | LIMITATIONS |
| Helical Piers | Steel shafts with helix plates screwed into stable soil | Wide range of soil types, stabilizing or lifting sinking foundations | Requires professional equipment |
| Push Piers | Steel piers driven into the ground using the weight of the structure | Heavy homes with severe settlement | Less effective in lighter structures or very weak soils |
| Slab Jacking (Polyjacking) | Pumping grout or foam under a slab to lift it | Concrete slabs like driveways, patios, or sidewalks | Not suitable for major house foundation repair |
| Concrete Underpinning | Excavating and pouring new concrete footings beneath foundation | Extremely heavy structures or deep foundation needs | Expensive, disruptive, and time-consuming |
Key takeaway: while every method has its place, helical piers are often the most versatile and efficient choice for long-term foundation stabilization in residential homes.
