Helical piers are a popular choice for foundation repair and new construction projects due to their versatility, ease of installation, and ability to provide strong support for structures. Helical pier installers use a variety of techniques to ensure that the piers are properly installed for maximum stability and longevity.

In this article, we will explore some of the top techniques used by helical pier installers to create sturdy foundations.
Pre-Installation Preparation
Site Evaluation
- Inspect the site to determine soil conditions, load-bearing requirements, and any potential obstacles.
- Use ground-penetrating radar or other technology to identify underground utilities or structures.
Foundation Design
- Collaborate with engineers to design a foundation plan that outlines the placement and depth of helical piers.
- Calculate the number of piers needed based on the structure's weight and soil characteristics.
Installation Process
Equipment Setup
- Position the installation equipment, such as a hydraulic drive motor or mini excavator, at the designated pier locations.
- Attach the helical piers to the drive motor or excavator using the appropriate extensions and drive heads.
Pier Installation
- Apply downward pressure to advance the helical piers into the soil while monitoring torque levels to ensure proper installation depth.
- Verify alignment and verticality of the piers using a laser level or other tools.
Quality Control
Load Testing
- Conduct load tests on a sample pier to verify its load-bearing capacity meets or exceeds design requirements.
- Adjust installation techniques if necessary to achieve the desired load capacity.
Documentation
- Record detailed information about the installation process, including pier depths, torque values, and any deviations from the original plan.
- Create an as-built report that outlines the final placement of the helical piers for future reference.
Post-Installation Considerations
Grouting
- Inject grout into the voids around the helical piers to enhance their stability and prevent movement.
- Use non-shrink grout to fill any gaps and ensure a secure connection between the piers and the foundation.
Final Inspection
- Conduct a final inspection to verify that the helical piers are properly installed and ready to support the structure.
- Address any issues or concerns before completing the project to avoid future complications.
