What is a Helical Pile? Find out why they’re a top choice among builders

A helical pile (or screw pile) is basically a large screw that we install in the ground below the frost line, with either an excavator or a skid steer that has a designated hydraulic motor attached.

If you imagine a regular household wood screw installed into a two-by-four or four-by-four, it’s the same principle. A screw pile has three distinct parts: The tube, the helix, and the attachment or pile head. Although, for the capacity numbers—such as tension and compression—of a helical pile to be reliable, it must have a true helix design.


At GoliathTech we’ve spent over 15 years since we’ve been in business conducting up to date research to make sure that our helical piles have a true helix design. The requirements are that both edges be parallel at the front and at the back as they start to pitch. Also, the pitch must be a true three-inch pitch, which means that for each revolution (or turn) of the helical pile, it goes into the ground three inches. Relying on solid numbers gives GoliathTech installers a foundation on which to build any project with confidence. Yet there are other factors that determine the strength of a screw pile.

Getting back to the analogy of the traditional wood screw, the deeper the screw goes into the wood, the stronger the screw becomes. It’s the same idea with a helical pile. The deeper we go into the soil, generally speaking, the stronger the pile is. Although when deciding on the depth, it’s important to consider the type of project as this plays a role. Check out our project page for a list of the types of projects that work best with helical piles


Whether you’re building a patio, a bridge or installing solar panels, a helical pile can go as deep as we need it to according to project specifications and the types of soil. We go as deep as necessary, so we have a solid foundation based on the characteristics of the soil.ol.


Many builders and developers opt for helical piles because they’re not weather-dependent, install rapidly and don’t require excavation, which means no damage to landscape or structures. GoliathTech helical piles are equipped with a nut-fastening system that allows the structure to be installed directly onto the piles. This feature prevents lateral or vertical movement and offers superior resistance to wrenching. We also offer a galvanized process that protects the steel against corrosion. In fact, we guarantee that our installations remain in perfect condition for years to come. Check out our GoliathTech screw piles warranty page to read what is covered under our warranty protection
