What Are Commercial Helical Pile Systems?
Commercial helical piles, also known as helical piers or screw piles, are steel shafts with helix-shaped bearing plates that can be turned into the ground to transfer structural loads past weak or variable soils into competent bearing strata.
Helical piles can support compression and tension loads, as well as lateral loads when properly configured, making them suitable for both new construction and retrofit applications. Installation torque is tracked 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 rely 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 limit the use of push piers. They also bring several advantages during installation:
- New or existing structures: Can be installed before construction starts or used to support existing foundations.
- Works in tight spaces: Compact equipment can accommodate restricted access and limited overhead clearance.
- Less site disruption: Installation requires limited excavation and produces minimal vibration.
- Flexible installation: Pile configurations can be designed 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 NV Waterproofing and Foundation Repair
Versatile Deep Foundation Support
Model 287 Helical Pile System
The Model 287 Helical Pile System delivers a versatile deep foundation option for new commercial construction and retrofit applications. Its steel shaft and configurable helix plates make it possible to design the system 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 combines a 2.875-inch shaft with a heavier wall for projects requiring greater structural capacity. It gives designers a higher-capacity option while keeping the relatively compact installation footprint of a helical pile system, which makes it useful for commercial foundations where loads, access or subsurface conditions require a more robust solution.

High-Capacity Support for Demanding Applications
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 expands the range of loads and soil conditions that can be addressed with helical piles while preserving the installation and verification advantages that make them well suited to demanding commercial deep foundation applications.

Heavy-Duty Support for High-Load Applications
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, offering an engineered solution for projects where smaller shaft systems do not meet design requirements.

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