World leader in Helical and Screw Pile foundations. A Techno Metal Post helical pile (or screw pile) is a giant metal screw that is installed in the ground by a certified technician until the exact bearing capacity for your structure is reached. They are screwed into the ground using proprietary machinery specifically designed by our engineers to provide you with an accurate measurement which is tested and validated right on site, ensuring the foundation of your structure is solid and secure. Techno Metal Post’s helical piles are manufactured right here in North America. Our posts are designed, engineered, and tested to the highest standards to ensure they withstand the toughest loads and conditions possible. Worried about frost-heaving?
