Commercial Helical Pile Systems in Sioux Falls

Often, yes. Helical piles can be installed with relatively compact equipment and produce limited vibration, which makes them an option for some occupied buildings and restricted-access areas. Feasibility comes down to access, overhead clearance, pile locations, structural requirements and operating conditions within the facility. 

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

Helical piles are built 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 screwed 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. The right deep foundation system depends on structural loads, soil conditions, access, project specifications and other site requirements.

Helical pile systems can be engineered and evaluated for use under applicable building codes. Code requirements vary by system, project and local jurisdiction, and commercial projects may require engineering, permitting and inspection. Blackburn Foundation Repair can coordinate with the project team to address applicable design and documentation requirements. 

There is no set installation depth for a helical pile. Piles are advanced until project-specific depth and installation torque criteria are met. 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 depends on pile model and configuration, soil conditions, structural loads and installation criteria. Commercial systems come in a range of capacities to accommodate different project requirements. The appropriate pile size, spacing and configuration are established 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 advanced into the ground with rotational force until they meet the installation criteria set for the project. The piles then transfer structural loads from the foundation to competent bearing soils below weaker or unsuitable soils.
