Helical Screw Piles – What are they and what do they do?

First I would like to say that although in the residential space helical screw piles are seemingly new, helical piles have actually been around since the early 1800’s and are used globally. The technology behind this type of foundation is well documented and is consistently reliable. On the basic end of the spectrum, consider a helical screw pile as a replacement for using a traditional sonotube form and poured concrete foundation. Resembling a large metal screw, helical piles are screwed into the ground by certified installers to required torque specifications.

GoliathTech Helical Screw Piles, are used for deep foundation support. They are manufactured in a wide variety of sizes and capacities for compression loading as well as tension loading. They consist of a round hollow tubular section of pipe as the lead section of pile shaft that is welded to a helical plate near the bottom of the pipe. Screw piles can be manufactured with a single, double or triple helix attached to the pipe shaft, depending on soil conditions and loading required. Helical piles are used to support everything from light residential decks, bridges, solar fields, signs, home additions up to multi-story commercial buildings requiring from 500 lbs to 175000 lbs of load per pile. Helical pile applications are endless.

GoliathTech helical screw piles have numerous advantages:

  • They do not heave due to frost (if properly installed)
  • They install quickly
  • ACQ approved for use with treated lumber
  • There is no soil displacement and therefore no soil to clean up
  • No waiting for concrete to cure and can start building immediately after installation.
  • Very high load capacities
  • More accurate load capacities over using concrete
  • Superior to concrete
  • Can be installed all year round without issue
  • They are economical
  • Can be installed using small equipment
  • Minimal environmental impact to root systems etc…
