Screw piles and Helical Anchors are unique among most other types of foundations or anchoring systems. They can be loaded immediately after installations unlike concrete or grout that takes time to harden.PURCHASE PILES
Screw piles, which are sometimes referred to as helical piers, helical anchors, and posts, are a screw-in pile used to build deep foundation systems and ground anchoring systems. A helical pile consists of a central shaft (circular or square) and a helix plate(s). The helix plates are press-formed with a predetermined pitch to resemble a screw are welded to the shaft. They are fabricated in various sizes and configurations to meet different types of loading and logistical requirements. The size and configuration of a helical pile is based on the design load the pile will carry, the existing soil conditions, the corrosiveness of the existing soils and the service life of the structure.
The load is transferred from the shaft to the helix plate(s) which is driven below grade into the strongest possible soil conditions. The helical pile is “screwed” into the ground by a high torque/low speed hydraulic drive motor which can be attached to numerous types of equipment including an excavator, skid steer, etc. Helical piles are unaffected by the presence of a high water table and caving soil conditions.
