What are Helical Piles?
Helical piles, also known as screw piles, screw anchors, helical piers, and helical anchors are a highly adaptable foundation lifting and stabilization system. It can be used to provide a strong foundation to new commercial structures or to provide anchoring for highly compromised residential or commercial foundations. A helical pile, or helical pier, is a steel shaft with round helix plates that provide foundation support for various types of structures. Rocky soils generally call for a smaller helix while marshy and clay soils require a larger one. Standard helix diameters range from 6 to 16 inches.
The helical pile is driven deep into the ground until it finds highly compacted soils or bedrock. By measuring turning resistance as a pier is driven, EagleLIFT contractors can determine when the pier has reached competent load-bearing soil. Not only do the helical plates advance the pier deep into the soil during installation, but they also help to anchor the pier solidly into place. Piers are then connected to the foundation with strong steel brackets. At EagleLIFT, our rigid three-bolt coupling connects helical lead sections and extensions making the pile resistant to bending. This method is superior to the pin and bolt coupling found in square-shaft helical pile solutions. Helical piles’ helix blade configuration achieves design depth and capacity. This process ensures a firm foundation for years to come at a competitive cost.
Why Helical Piles?
Helical piles with polymer injections are superior to many other new construction structural reinforcement methods, facilitation soil stabilization, and foundation settlement. The rigid three-bolt coupling which connects helical lead sections and extensions makes the pile resistant to bending, unlike the pin and bolt coupling found in square-shaft helical pile solutions.
Commercial helical pier installation can be performed quickly providing a firm foundation for the lifetime of the building. They are a great alternative to the traditional concrete caissons for new construction applications in commercial projects.
When used for commercial buildings, the helical piles are installed before the concrete slab is poured. We offer commercial helical piles installation throughout California and Nevada.

How the Polymer Injection Process Completes Helical Pier
Helical Pile Systems are able to provide substantial anchoring for the foundation against deep highly compacted soils and bedrock. In the topsoils, however, there is a substantial risk that the soils can migrate or wash away from the anchors and the building. This is because the home’s weight is not providing the compressive strength on the soils as it was before the piers. EagleLIFT remedies this by stabilizing the soils in the higher soil elevations with our chemical grout polymer injection process. The polymer, once injected, moves throughout the soil in liquid form and then densifies and compacts the soil and mitigating settlement.
Commercial Stabilization Using Helical Piles with Polymer Injection
Helical piles can be further stabilized with the addition of a polymer injection. EagleLIFT stabilizes the soils in the higher soil elevations with our chemical grout polymer injection process. The polymer moves throughout the soil in liquid form and then densifies and compacts the soil, mitigating settlement.
EagleLIFT will inspect your commercial or residential foundation to determine if helical piles are the right approach for your foundation issues.
Request an inspection if you notice:
- Bulging exterior walls
- Large cracks – larger than ¼ of an inch – in your concrete
- Sloping floors – a ball placed on the floor should not roll on its own
- Sticking windows or doors
- Cracks in walls or ceiling of 1/8th and inch or larger
Lifting the foundation to its original position has the potential to close cracks in your foundation and return doors, locks, and windows to their original functionality.
