What Are Helical Screw Pile Foundations?
First invented nearly two centuries ago to support structures in saturated and weak soils, today you'll find helical piles under everything from small-scale residential to high-capacity industrial construction
The Design of a Postech Helical Screw Pile
Pile Cap
Easily transition from the foundation to any structure with a limitless number of designs for the pile top
Thermal Insulation
Special insulation in the frost zone protects your foundation from movement during freeze/thaw cycles
Galvanized Steel
Every screw pile we install is protected by a galvanized coating, providing long-term defense against corrosion
Air Chamber
A protected air chamber at the bottom of your screw pile adds even more protection against frost and freezing.
Blade (Helix Plate)
The blade turns the pile down into the soil and anchors it firmly. This is the "secret sauce", offering immense load capacity in a compact package.
How is a Helical Pile Foundation Installed?
How Does a Helical Pile Foundation Work?
As a helical pile is installed, the soil exerts pressure on the helix plate.
This pressure serves to lock the pile in-place, ensuring it won't move even in challenging soils.
We're able to by-pass weak, saturated, or poor-quality layers to anchor in firm soils that won't move.
If your structure loads are particularly heavy, we can install the piles down to bedrock which increases foundation strength.
Build on a firm foundation that's tougher and longer-lasting than other options, giving you total peace-of-mind.
What Can You Build on a Helical Pile Foundation?
The short answer? If you can build it on poured or driven piles, odds are you could use a helical foundation instead! But, to spark your imagination, here's some of the common use-cases...
How Do Helical Piles Compare to Concrete Foundations?
This is the big one - how do helical piles stack-up when compared to concrete? You might just be surprised...
Speed of Installation
Helical piles are, on average, anywhere from 75% to 90% faster to install than concrete.
Site Prep
While concrete requires relatively laborious prep (clearing, digging, formwork, etc), helical piles need virtually none at all.
Frost-Resistance
Thanks to their unique design, and our patented Thermal Insulation, helical piles will not experience movement due to frost.
Land Impact
Concrete can have a negative impact on the land. Helical piles have a minimal footprint, use less material, and can be 100% recycled.
Site Access
Because the materials and equipment for a helical foundation are minimal, they can be installed in areas concrete simply can't go.

What exactly is a helical screw pile?
Picture it like a large, extremely heavy-duty "screw" that serves as a deep foundation for your project.
The helix plate (or blade) allows the pile to smoothly rotate into the ground - eliminating the need for disruptive and messy excavation. Once in the ground, that same helix plate anchors firmly in the soil to deliver big load capacity in a compact package.Are your helical piles better than concrete?
We're (obviously) a bit biased here, but in many cases the answer is yes! Some of the biggest advantages that cause people to choose helical piles are:
● Speed of installation● No excavation or mess● Zero cure time● Resists frost-heave● Significantly less land impact● Works in wet and weak soils● Goes where concrete can't● Can be used in marine environments
While concrete is not a bad foundation, our customers find that helical piles are an easier, quicker, and more economical choice.Since helical piles are made from steel, will they rust?
Technically, yes, a helical pile will eventually rust - but that won't occur for a very long time.
All our Postech piles come with a hot-dip galvanized coating for exceptional protection against corrosion. In fact, our piles are rated for a minimum lifespan of 75 years and come with a lifetime warranty. That means they'll far outlive a typical concrete foundation, so you can build with confidence.Will helical piles shift, sink, or heave due to frost?
No, our helical piles will not move due to the effects of frost. Helical piles are naturally-resistant to frost thanks to their design, plus our Postech piles have a special thermal insulation for even more protection.
The result? You'll never have to worry what winter will do to your foundation.What kinds of projects can you use helical piles for?
A better question here would be, "What can't you use helical piles for?"
Helical foundations are incredibly versatile, capable of supporting anything from a backyard deck to industrial structures. From light to heavy loads, we stock a range of pile sizes to suit your exact needs.
Essentially, if you can build it on a poured concrete or driven pile foundation, you can likely build it on helical piles!Are your helical piles engineer-approved and code-compliant?
Yes! Every single one of our helical piles are engineer-approved for use in New Brunswick (and throughout North America).
Postech carries CCMC, CWB, and ICC certifications so you can be confident in the validity and quality of our products. We also offer a complete range of engineering services through our partners - from plan reviews to complete foundation designs.Can you install helical piles in winter?
Absolutely. Because we don't need to dig holes or pour concrete, our team can install helical piles even in freezing temperatures. It's actually the perfect way to get a head-start on your project and be 100% ready to start building when the spring thaw hits.
