Commercial Helical Pile Systems in Nashville

In some cases, yes. Helical piles can be installed with relatively compact equipment and produce limited vibration, making them an option for some occupied buildings and restricted-access areas. Whether it’s feasible depends on access, overhead clearance, pile locations, structural requirements and operating conditions within the facility. 

No. Helical piles work in many soil conditions, but they are not appropriate for every site. Dense material, cobbles, boulders, shallow bedrock and other subsurface conditions can limit installation. A review of site conditions and geotechnical information helps determine whether helical piles are appropriate and how the system should be configured. 

Helical piles are designed for long-term structural support. Expected service life depends on the pile system, soil conditions, corrosion potential and any required protective coatings or treatments. Durability and corrosion protection should be evaluated based on the conditions and required design of the specific commercial project.

Helical piles are twisted into the ground rather than driven or installed in a drilled excavation. They typically require smaller installation equipment, generate less vibration and soil disturbance, and do not require concrete curing. Which deep foundation system fits depends on structural loads, soil conditions, access, project specifications and other site requirements.

Helical pile systems can be designed and assessed for use under applicable building codes. Code requirements depend on the system, the project and the local jurisdiction, and commercial projects can require engineering, permitting and inspection. The Foundation Specialists can work with the project team to address applicable design and documentation requirements. 

There’s no standard installation depth for a helical pile. Piles advance until project-specific depth and installation torque criteria are achieved. Required depths can vary across the same site as soil conditions change, so piles are installed based on actual subsurface conditions instead of a single predetermined depth. 

Helical pile capacity varies depending on the pile model and configuration, soil conditions, structural loads and installation requirements. Commercial systems are available in a range of capacities to accommodate different project requirements. Pile size, spacing and configuration are determined as part of the project-specific design.

Helical piles are steel foundation supports built from a central shaft and one or more helix-shaped plates. They are turned into the ground using rotational force until they reach the installation criteria established for the project. The piles then transfer structural loads from the foundation to competent bearing soils below weaker or unsuitable soils.
