What Are Helical Piles & Anchors?

Helical piles — also known as helical piers, screw piles, or helical anchors — are deep foundation elements consisting of a steel shaft with welded bearing plates (helices). These are mechanically screwed into the ground to transfer structural loads through weak or poor soil into stronger, load-bearing strata below. Their design makes them highly versatile for supporting compression and tensile loads in residential, commercial, and infrastructure applications.

Unlike traditional driven piles or drilled shafts, helical piles install with no vibrations, minimal excavation, and immediate loading capacity, making them ideal for sites with limited access, existing structures nearby, or sensitivity to disturbance.

Engineered Strength from the Ground Up

Helical pile anchoring provides durable, dependable support for foundations, tiebacks, soil retention, and underpinning — without the noise, spoil removal, or long cure times of conventional deep foundations.

Challenges that Helical Piles Solve

Poor or Unstable Soil Conditions

Weak, compressible, or soft soils fail to support structural loads, leading to settlement, tilting, or cracking of foundations. Helical piles transfer loads to deeper, competent soils.

Excessive Vibration Risks from Traditional Pile Driving

Conventional driven piles create significant vibration and noise — problematic for urban, historic, or sensitive sites. Helical piles install without vibration, protecting adjacent structures and systems.

Complicated Foundation Access

Some sites have limited access, low headroom, or environmental restrictions. Helical pile systems install with compact equipment and require minimal staging area.

Key Advantages of Helical Pile Anchoring

Rapid Installation

Helical piles install quickly compared to drilled shafts or driven foundations, often allowing project milestones to be met on accelerated schedules.

Minimal Vibration & Disturbance

Installation generates virtually no vibration or noise, making helical systems ideal for urban, residential, and sensitive environments.

Immediate Load Capacity

Once installed to the engineered torque specification, helical piles can be loaded immediately — eliminating cure times required for concrete foundations.

Versatile Applications

Helical piles are suitable for compression and tension loads, underpinning, tiebacks, soil retention, slope stabilization, and more — offering adaptability across projects.

Helical anchors can be utilized for construction over poor soils. This bridge located in Wolfeboro, New Hampshire was founded on 24 piles.
