A helical pier installation: quick and easy!
While construction projects usually leave you tired, frustrated, and counting down the days, with GoliathTech’s help, you’ll find yourself at ease. The expertise of our certified installers, combined with the cutting-edge technology used by our team, allows us to gather and then calculate all the information that we need for the project’s success; and ultimately, to leave you with a project that you’ve only imagined in your dreams.
Steps 2 and 3 is where the helical pile (pier) installation occurs
Step 1
Planning your project
First and foremost, it is essential to determine the nature of your project and the contractor who will build it, as well as the various needs associated with it. Evaluate the time, budget, and space available to you so that you can pass this information on to one of our certified installers, when the time comes.
Step 2
Consultation and estimate
Our certified installers are waiting for your call! With the help of precise calculations and an analysis of the type of soil and the load to be supported, they will be able to provide you with an estimate of the cost of the product and will design a solution tailored to your needs.
Step 3
Installation
The big day has finally arrived. The helical piers (piles) will be screwed in as deeply as possible. It’s likely that during the installation, some technical details will need to be adjusted, such as the length of the piles or the size of the helices. Our experts know how to react quickly in order to ensure the absolute stability of your foundation.
Step 4
Everything is ready for construction
There’s no delay or clean-up required between the end of the helical pier installation and the start of construction. As soon as the last helical pier (pile) is anchored into the ground, your contractor can start building your project.

Frequently Asked Questions
How much weight can a helical pier support?
Since this depends on the soil type, it's at the time of installation that the weight that each helical pier can support will be determined. It's important to note that the more compact the soil, the greater the bearing capacity of the helical pier. This capacity (also known as compression or tension) is confirmed at the time of installation, in accordance with the quality standards and requirements met by all GoliathTech helical pier. In some cases, a certificate may be issued by an engineer to validate the compliance of the upcoming work.
How much does a helical pile (pier) cost?
Contrary to popular belief, GoliathTech helical pile (pier) are a cost-effective long-term solution. However, there are a number of factors to consider when estimating the cost, such as the structure to be supported, soil type, length of helical pile (pier) required, and the accessibility of the site. Please contact a GoliathTech certified installer to learn more.
What is the recommended distance between each helical pier (pile)?
Depending on industry standards and the type of structure to be supported, a distance of 8 to 10 feet is generally recommended between each helical pier (pile).
What are the possible approaches if there's a rock in the soil?
In most cases, we can shift the rock slightly to install the helical pier. If the GoliathTech certified installer is unable to move the rock due to its size, then the pile can be installed in another location, providing the project allows it. If the location of the structure cannot be changed, the installer will typically use a mini excavator adapted to this type of scenario. This will allow the GoliathTech expert to install the helical pier leaving as small of a footprint as possible.
Can helical pier be installed under an existing structure?
Absolutely! Although, helical piers must be installed in close proximity to the structure being supported. To install helical piers in the middle of an existing structure, access must be provided. For example, it is recommended to remove a few boards from a wooden deck to install helical piers in an otherwise inaccessible area.
Does the helical pile (pier) need to be covered with a plastic casing to protect it from freezing?
Not at all. The double protection of our helical piles (piers) prevents ground movement due to freezing and thawing at all levels: from the inside and from the outside. Polyurethane insulation prevents ice from forming inside the helical piles (piers) and keeps them above freezing. In addition, the piles are installed below the frost line and the helix at the end of the pile serves as an anchor that prevents the helical pile (pier) from rising to the surface during periods of intense cold.
Are your helical pier (pile) surrounded with a polyurethane/plastic sleeve?
Since our helical piers (piles) are comprised of a smooth metal tube and are installed below the frost line, a coating is unnecessary. Also, a polyurethane sleeve would tend to rise to the surface due to the freeze/thaw cycle, without necessarily returning to its original position over time. This can lead to support problems and could damage your structure in the long term.
