What Are Helical Piles

Helical piles are sometimes known as helical piers, helical anchors, screw piles, or screw piers. Often, all these terms are used interchangeably. This is a detailed guide on helical piles.

>> What are Helical Piles?

Helical pile/pier are segmented deep foundation systems with helical bearing plates welded to a central shaft that can be round or square manufactured from high strength steel. The load of a structure is transferred from the shaft to the soil through these bearing plates. A helical pile concept is based on the principle of turning a screw into stable sub-soil strata until the design torque applied indicates that the necessary load capacity has been achieved. Helical piles work for both compression, tension and lateral loads.

>> What do Helical Piles do?

Helical piles, piers, anchors, screw-piles, are deep foundation system solutions used to support new or repair existing foundations. Due to their engineer design and ease to install, they are most used whenever soil conditions prevent standard foundation solutions. Instead of requiring large excavation work, they screw into the ground. This minimizes installation time, minimizes soil disturbance and contamination of the surrounding environment. Helical piles transfer the weight of the structure to load bearing soil stratum via the helical plates welded into a central shaft.

>> How are Helical Piles made?

Helical piles are manufactured from High strength steel and galvanized to protect it from corrosion. Generally, they have a slender steel shaft with one or more helical plates welded at the tip to provide support to the structure they hold. Helical piles are screw into the ground with a hydraulic motor attached to a machine such as a backhoe or excavator and provide support through soil bearing plates and along the shaft.

They come in many lengths and are often the foundation of choice for retro-fitting existing buildings or new, urban construction, due to their small footprint and ability to create minimal disturbance to surrounding structures. Helical piles are engineered for a minimum life expectancy of fifty plus years and can last an excess 100 plus years, depending upon surrounding conditions.

>> When to use Helical Piles?

Helical piles/piers are used in the civil infrastructure for both new and existing structures in the residential as well as in commercial applications, industrial, electrical and renewable markets.

Helical piles are a versality deep foundation system that can be used for example:

  • For new residential construction and for repairing existence foundations.
  • Commercial and industrial new constructions and repairing existence structures.
  • Electrical transmission and telecommunication tower foundations.
  • Boardwalk and environmental walkways.
  • Instant street lighting foundations.
  • Solar panel structure foundations
  • Tieback and soil-nailing
  • Pipeline

>> Benefits of Helical Piles

Helical piles produce minimal disturbance to the surrounding and minimizes or eliminates the use of concrete – a major pollutant. They are also 100% reusable. We also use high quality recycled steel for its fabrication process, making the fabrication process environment friendly, and reducing the overall carbon footprint.

Helical piles don’t require excavation for its installation, reducing the overall time and cost of the project. Since it does not require digging, it also produces minimal waste and disturbance to the surrounding area.

The most significant advantage of using a helical piles is that it can be loaded immediately. Unlike conventional foundations, it doesn’t require time to settle down. Also, it does not require any additional machinery, such as a crane or large drilling equipment for its installation.

Helical piles produce minimum noise during their installation; therefore, easily used in the restricted areas.

The best thing about the helical piles is that they can be loaded immediately after their installation. Unlike conventional foundation systems, they don’t need time to cure.

Unlike conventional foundation systems, helical piles don’t need time to cure; therefore, installation can be done throughout the year. Whether it is winter, summer, or rainy season, they can be installed easily in any season.

Helical piles versatility allows it to be use for multiple applications on very challenging soils conditions that otherwise will be impossible with traditional foundations. Since they don’t require large machinery and multiple equipment for their installation, they can be easily used in areas with difficult access that tend to increase mobilization costs.
