Helical Anchor Installation Relies Upon Accurate Torque Measurements

Helical anchors enjoy widespread use today to help stabilize and secure above-ground structures, especially when that structure is built on ground that may be or has become unstable. The anchors themselves are steel shafts with helical coils or plates welded on at an angle. The shafts are screwed into the soil beneath the foundation to a depth that enables the coil to support the load. When foundation drilling calls for helical anchors, the depth of the anchor is drilled into the ground is determined by precisely measuring the torque it takes to turn the anchor. Generally, the higher the torque value the more stable the soil. This gives soil and structural engineers an accurate indication of the load-bearing capacity of the helical anchors.
