What Are Commercial Helical Pile Systems?
Commercial helical piles, sometimes called helical piers or screw piles, are steel shafts with helix-shaped bearing plates that are twisted into the ground to transfer structural loads through weak or variable soils to competent bearing strata.
Helical piles can support compression and tension loads, as well as lateral loads when properly configured, making them a fit for both new construction and retrofit applications. Installation torque is monitored as each pile is installed to help verify it has reached the required capacity.

Why Engineers and Contractors Choose Helical Piles
Helical piles don’t depend on the weight of an existing structure for installation. That makes them a versatile choice for new construction, additions and existing structures where building weight, access or site conditions may rule out push piers. They also bring several advantages during installation:
- New or existing structures: Can go in before construction begins or be used to support existing foundations.
- Works in tight spaces: Compact equipment can work with restricted access and limited overhead clearance.
- Less site disruption: Installation calls for limited excavation and generates minimal vibration.
- Flexible installation: Pile configurations can be engineered around project loads and subsurface conditions.
- Verified as installed: Torque is monitored during installation to help confirm each pile meets project requirements.

Commercial Helical Pile Solutions from Vesta Foundation Solutions
Versatile Deep Foundation Solution
Model 287 Helical Pile System
The Model 287 Helical Pile System offers a versatile deep foundation option for commercial new construction and retrofit applications. Its steel shaft and configurable helix plates allow the system to be designed for site-specific loads and soil conditions, while multiple bracket options cover both new foundations and existing structures that need additional support.

Increased Capacity for Commercial Foundations
Model 288 Helical Pile System
The Model 288 Helical Pile System pairs a 2.875-inch shaft with a heavier wall for projects requiring greater structural capacity. It offers designers a higher-capacity option while preserving the relatively compact installation footprint of a helical pile system, making it useful for commercial foundations where loads, access or subsurface conditions require a more robust solution.

Higher-Capacity Support for Demanding Projects
Model 350 Helical Pile System
For commercial projects with heavier structural demands, the Model 350 Helical Pile System provides a larger-diameter, heavier-wall foundation support option. The system widens the range of loads and soil conditions helical piles can address while keeping the installation and verification advantages that make them well suited for demanding commercial deep foundation applications.

Heavy-Duty Support for High-Load Projects
Model 450 Helical Pile System
The Model 450 Helical Pile System delivers a heavy-duty deep foundation option for commercial projects carrying high structural loads. Its larger-diameter steel shaft and greater mechanical capacity extend the range of applications that can be supported with helical piles, providing an engineered solution for projects where smaller shaft systems do not meet design requirements.

Engineered, Code-Compliant Helical Pile Design
Supportworks helical pile systems have been evaluated for use under applicable building codes, with system capacities and installation requirements established through product testing and evaluation. Project-specific design considers structural loads, soil conditions, pile configuration and required capacity.
Helical pile systems are designed for long-term structural support, with various shaft sizes and helix configurations available to meet project requirements. Their design also considers the long-term durability of steel components below ground.
