Contractors in Virginia can purchase professional-grade helical piers directly from Walder Foundation Products, a family-owned distributor based in Ashland, Virginia. This guide covers the core components of helical pile systems, the specialized drive equipment required for installation, and how to source ICC-rated materials for both new construction and underpinning projects.
Understanding Helical Pile Components
A helical pile is a deep foundation element that transfers structural loads to stable soil layers through a rotating shaft and helical plates. Unlike driven piles, helical piles are screwed into the ground, which minimizes vibration and allows for precise depth control. This makes them ideal for residential and commercial projects where adjacent structures must remain undisturbed.
Lead Sections
The lead section is the first piece driven into the ground in a helical pile system, featuring one or more helical plates that pull the pile downward as it is rotated into place. These sections come in single and double-helix configurations to match different soil conditions and load requirements. Contractors can find a variety of ICC-rated lead sections in the lead sections catalog.
Extensions
Extensions connect to a lead section to extend a helical pile deeper into the ground until it reaches stable, load-bearing soil. Available in multiple lengths, these ICC-rated round shaft extensions let contractors adapt each installation to the specific depth and soil conditions of the job site. Whether it is a foundation repair, underpinning project, or new construction application, the correct extension length is critical for achieving the required torque.
Brackets and Caps
Brackets and caps create the connection between a helical pile and the structure it is supporting, transferring load from the foundation down through the pile system. Our ICC-rated brackets are built for both underpinning existing foundations and new construction applications, giving contractors a secure, code-conscious connection point for every helical pile installation. You can browse the full range of brackets and caps to find the right fit for your specific shaft diameter.
Selecting the Right Drive Equipment
Installing helical piles requires specialized equipment capable of generating sufficient torque to drive the pile into the soil. The choice of drive equipment depends on the size of the pile, the soil conditions, and the accessibility of the job site. Walder Foundation Products supplies professional-grade drive motors and handheld units to ensure contractors have the right tools for the job.
Helical Drive Motors
For larger diameter piles or deeper installations, a helical drive motor is the preferred choice. The Digga Helical Drive Motor, rated at 10,000 ft-lbs, is the pinnacle of helical pier drives for mini excavators. This high-torque unit allows for rapid installation of heavy-duty piles in challenging soil conditions. Contractors can view the Digga Helical Drive Motor for detailed specifications and availability.
Handheld Units
In tight spaces where mini excavators cannot operate, a handheld unit provides a practical solution. The Digga Helical Handheld Unit, rated at 6,000 ft-lbs, allows a single operator to drive smaller diameter piles into the ground. This unit is particularly useful for residential projects where access is limited. You can explore the Digga Helical Handheld Unit to see how it fits into your equipment lineup.

Installation Workflow and Best Practices
Successful helical pile installation requires a systematic approach to ensure structural integrity and code compliance. The process begins with a site assessment to determine soil conditions and required depth. Once the site is prepared, the lead section is positioned and driven into the ground using the appropriate drive equipment.
Site Preparation
Before driving any piles, the area must be cleared of obstructions and marked with stakes to indicate pile locations. It is important to verify utility lines and ensure that the ground is stable enough to support the drive equipment. Proper site preparation prevents damage to the pile and ensures accurate placement.
Driving the Pile
The lead section is driven into the ground until the required torque is reached. Extensions are then added as needed to reach the target depth. The pile is driven in a controlled manner to avoid bending or damaging the shaft. Monitoring torque and depth is essential to ensure the pile is bearing on stable soil.
Connecting to the Structure
Once the pile is at the correct depth, the bracket and cap are installed to connect the pile to the structure. The load is then transferred from the structure to the pile, stabilizing the foundation. Proper alignment and secure fastening are critical to the long-term performance of the system.
