Piling Systems Helical Screw Piles

Although Helical Piles are the right answer for certain scenarios, Ground Improvement methods are often a much more ideal solution, dependent on your specific requirements. That’s when contacting us to advise you on which system to employ for a particular project is always best. That said, let’s dive into what Helical Pile foundation systems  are all about. Helical Piles consist of strong galvanized steel sections with a helical lead section screwed deep into the ground until they reach stable soil. These pilings are then attached to the existing foundation. 

Helical pile (helical screw piles, helical piers, helix anchor, helical anchor, screw pile, screw anchor, helical pile, torque anchors, auger screw piles, helical torque anchor, helix pile) foundation systems are used not only on new structure construction sites, but are also often utilized to repair existing failing foundations or used in tight-access situations for additions or renovations of existing structures.  Although Helical Screw Piles are a sound solution for supporting foundations where soil conditions are less than ideal, there are a number of ground improvement methods that may be more suitable and more reliable than helical’s. Helical piers can be installed to improve the integrity of an existing foundation to allow for greater load-carrying capacity or to upgrade historic structures to new code requirements. Helical piers are twisted or screwed into the ground with a hydraulic drill attached to an excavator. The load capacity can be determined based on correlating the helical pile type to the final installation torque. Full-scale tension or compression load test can then be conducted to verify the installation and confirm the design.
