How It Works

Home / How It Works
Nova Helical Piles LTD

Resembling a large screw, screw piles are installed deep into the ground, beneath the ground freezing level, to solidly support the structure of your project. This is an advantageous alternative to form tubes and is less expensive than concrete foundations.

Opt for a simple and rapid installation, without excavating.

  • No damage to landscape or structures
  • Perfectly levelled structure
  • No delays between the end of the installation and the beginning of works
  • Ideal for restricted spaces
  • Possible no matter the season
  • Removable and reusable system


Solar Panels

Secure panel support

Given an ever-increasing demand for solar power and other renewable energies, GoliathTech has ingeniously adapted its helical piles for use in anchoring solar panels. Wind resistance and durability are important factors with solar panels. GoliathTech’s helical piles are an anchoring solution that will stabilize and support the panels, in any soil or weather condition, which ultimately protects them over the long term.

GoliathTech helical pillars are a better and easier solution than traditional concrete supports. Quick to install using only small equipment, the solar rack and panels can be raised immediately because no drying time is required.

No damage from cold or frost and no movement!

GoliathTech screw piles solidly support decks over the long term, are much quicker to install, and allow deck construction to begin immediately after the installation. Plus, they’re installed using small equipment that leaves no damage to the yard – perfect for backyards where space can be tight.

Strengthening the existing foundation of a structure will save you thousands of dollars versus replacing the entire foundation!

Underpinning becomes necessary when a foundation can no longer fully support the load of the structure that rests upon it.

At GoliathTech, we manufacture special underpinning brackets to stabilize and/or lift sunken structures. Our helical piles are planted deeply into the ground beneath the structure until they reach dense, compact and stable soil. Underpinning the foundation stabilizes and gives increased strength to the building’s structure over time.

Steel + ZN

Superior quality galvanized steel, worthy of the most ambitious projects

Our galvanizing process protects steel against corrosion to guarantee maximum product longevity. No matter the area where they are installed, GoliathTech piles remain in perfect condition for a very long time. It’s guaranteed!

GoliathTech Double Protection

Fights frost and thawing soil movements on all fronts: inside-out

Piles designed to last. Guaranteed.

1. The inside of GoliathTech piles is filled with polyurethane to prevent ice accumulation inside the pile. (Piles with a diameter over 6 5/8" do not contain polyurethane.)
2. The 60Ksi steel piles are fully galvanized to protect the tubes as well as the heads and helixes against physical deterioration. (Piles 4 1/2" and larger use 55Ksi steel.)

Exclusive Anchoring Solution

When detail makes the difference

GoliathTech pile heads are equipped with a nut-fastening system. This exclusive anchoring solution allows the structure to be installed directly on the piles, thereby preventing lateral or vertical movement.

  • Zero movement
  • Superior resistance to wrenching


Piles with reinforced joints

The GoliathConnect joint system allows a pile to be extended by joining two tubes using a locking bolt. Contrary to the competition’s solution, this innovation strengthens long piles and eliminates risk of movement.

Choosing The Right Pole

Piles for each project

GoliathTech offers a vast array of tubes and helices according to the weight to be supported and the type of soil. Each GoliathTech product is thus perfectly suited to your project.
