Techno Metal Post helical foundations, a type of helical pile or screw pile, are rotated into the ground with our specialized machines until a certain torque and depth are reached to meet the bearing load requirements of the supported structure. Techno Metal Post helical foundations are made from Hollow Structural Steel (HHS) that is compliant with ASTM A500 grade C. They are designed, tested, fabricated, and installed in compliance with United States, Canadian and European building codes. Couplings connecting sections of shaft together are fully welded which provides maximum strength and rigidity and enhanced buckling resistance compared to similar products with only bolted couplings. Many shaft and helix sizes are available to fit the needs of a supported structure and to accommodate site specific soil conditions. Our engineering department can assist you in determining the appropriate sizes for the specific type of structure planned and soil conditions on your building site.
The insertion into the ground is carried out by our certified installers using our specialized hydraulic equipment which screws the pier until the proper soil layer is reached, thus providing the required bearing capacity for your project. The bearing capacity is confirmed on site with the use of our installation equipment which measures the torque (twisting force) during the installation of the pier. In this way, our certified installers know the exact load capacity for each pier after installation.
To protect the pier from ground movement, our exclusive green sleeve is placed over the pier during installation. During freeze/thaw cycles or in the presence of swelling clay, it is the sleeve that slides along the shaft of the pier following the possible movements of the ground. The Techno Metal Post will not move and thus ensures the stability of the structure.
Pier caps are installed on the head of each pier to secure the structure for the planned project. Several models and sizes of pier caps are available to accommodate different dimensions or materials. Techno Metal Post manufactures several models of helical piers for different projects: small piers for light applications (decks, verandas) and more robust piers for heavier loads and applications (cottages, garages, buildings).
Techno Metal Post makes life easier for anyone with a construction project that requires a foundation in almost any type of soil.
