A helical anchor/pile is an extendable deep foundation system with helical bearing plates welded to a central steel shaft. Load is transferred from the shaft to the soil through these bearing plates.
Due to their design and ease to install, they are most commonly used whenever soil conditions prevent standard foundation solutions. Helical anchors are easily installed by hand-held equipment, mini-excavators, skid steers, backhoes, trackhoes, or crane-supported rigs to accommodate just about any application they are being installed to, in order to stabilize foundation and retaining walls with unbalanced earth pressures. Helical anchors are extremely versatile and economical solutions for a wide range of commercial projects and they also provide the convenience to immediately load and test anchors.
Helical Anchors and Tiebacks are a highly economical solution to structure and earth retention applications. OX Foundation Solutions is one of the leading experts in utilizing Helical Anchoring and Tieback systems. Our team of experts has over 30 years of experience in the design and use of helical in tieback and anchoring applications.
The Helicals are hydraulically installed into the existing soils until they reach the required load capacities and the required installation depth. They can be installed to depths of anywhere from 10 feet to 250 feet! Once the Helicals have been installed, you can then add required end attachment for the various applications. From guy wires to building and slope retention, there is always a solution that can be obtained utilizing Helical anchors.
