Modern helical ground anchoring engineering and design have changed the utility pole construction process by allowing for cost-effective solutions that can be quickly laid out and installed. These utility bases are also commonly described as helical piles, piers, anchors, and ground screws.
Helical utility bases are ideal for various vertical loads, including street and parking lot lighting, decorative light or signage poles, highway-facing signage, and support for structural foundations when needed. The bases we design and install are also useful for constructing solar panels, wind turbine towers, and telecommunication towers. Pier segments can be joined with secure couplings to achieve the depth needed to provide stability for the intended above-ground use. Pier depth is only practically limited by soil density and composure.
Helical piers used for pole bases and anchoring are installed to reach below the surface to competent soils that remain stable and provide a predictable load-bearing capacity over the years. One significant advantage of helical utility bases is that they can be safely and securely installed in even weak topsoil, fill material or areas with a high water table.
The piers are designed so that both topsoil and subsurface soil is minimally disturbed, reducing the need to excavate the construction area. The helical design does not “auger” the soil but works as a screw-inclined plane causing minimal soil disturbance. Concrete is not needed to secure the pier, allowing for installation to be done in most weather conditions and throughout the year. Various sizes and material configurations are available in helical base construction, allowing our designers to match them with your facility’s soil and terrain conditions and load requirements.
