This heavy-duty polyethylene sleeve has been specially designed to surround the pile and prevent it from being affected by ground movement.
One of the major challenges a helical pire foundation must face is resisting ground movement. When the ground moves, it tends to pull or push on the shaft of the pile. Techno Metal Post designed and developed this proprietary green-coloured sleeve that reduces the grip of ground movement on the pile.
The sleeve size is adapted to that of the pile and is installed around the pile when it is screwed into the soil. Once in place, the sleeve slides up and down the pile with natural ground movement. It allows the pile to remain perfectly stable during freezing, thawing or drought periods.
As with our helical pires, Techno Metal Post has its own plastics department for the manufacturing of our exclusive sleeves in Quebec, in a variety of sizes. This gives us complete control over the quality of the product and, consequently, that of your helical pire foundations.
