Silo and greenhouse

Over the last few years, there have been reports of grains silos or greenhouses collapsing. Why did this happen? The likely answer is that those structures had been built on unstable ground. One thing is certain, no one would want a silo to collapse while it’s being filled!
Screw piles can offer you unparalleled stability for your structure’s foundations.

High load bearing capacity

We all know that heavy loads can be a cause of structural instability. Pro Post Foundations galvanized steel piles can support 25% more weight than any other pile. Moreover, the weight supported by farm structures such as grain silos varies widely over time. Our piles will not be affected by the weight variations since they are firmly anchored into the ground thanks to the helix plate set at the bottom of the pile shaft.

Stability and solidity

Temperature fluctuations can damage traditional foundations. Fissures and cracks can appear in concrete foundations as a result of frost and thaw cycles. As mentioned before, our piles are anchored below the ground’s frost line are therefore unaffected by soil movements due to temperature fluctuation. Screw pile foundations will be stable and durable, and will spare you unpleasant surprises!

Quick and easy installation

Since each project is unique, the number, size and placement of the piles are determined according to the type of structure and its weight as well as the type of soil where they will be installed. 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.

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.
