Commercial signs and billboards

Whether it be for a municipal billboard to welcome passers-by, a commercial sign to announce the buildings’ occupants, an advertising billboard, a park’s signage installations or a panel indicating your address, we are surrounded with signage that come in all shapes in forms (electronic, illuminated, static or dynamic, etc.).
Since your commercial sign reflects your identity, you want the posts that hold it up to remain straight and level. Pro Post Foundations screw piles are the most sturdy and durable solution for your signage foundations.

Stability and solidity

Screw pile foundations reach beneath the ground’s frost line, which means that they are impervious to ground movements due to frost and thaw cycles. Our screw piles have a high load bearing capacity and are solidly anchored into the ground. No need to excavate nor to pour concrete! Installation is done using a Kubota mini-tractor equipped with lawn tires to avoid damaging your property. Installation is quick and can often be completed in just one day!

Moving and reusing screw piles

If you have to move your signage, no problem! Our piles can be easily removed and relocated elsewhere thanks to our Kubota mini-tractor. Our professionals will be there to help you every step of the way, and will be available in the future, if the need ever arises.

Quick and easy installation

Our professionals will determine the number, size and placement of the piles you need according to the structure and the type of soil. Our piles come in many sizes. We offer piles ranging in diameter between 1 ⅞ and 6 ⅝ inches equipped with helix plates (the screw that allows to drive the pile down into the ground) anywhere from 8 to 36 inches in size.


For sturdy and reliable post foundations and impeccable service, contact one of our Pro Post Foundations accredited dealers to obtain a fair work estimate.

Our Piles

Similar to a giant screw, the piles are driven into the ground using specialized equipment and are anchored into place thanks to a helix plate situated at the bottom of the shaft. The piles can therefore securely support structures such as houses, patios, garden sheds, fences and much more. The piles can be used to support new or existent structures.
