Screw Piles also known as helical piles, are constructed using steel shafts with helical flights. The shafts are advanced to bearing depth by twisting them into the soil while monitoring torque to estimate the pile capacity. A thorough understanding of the subsurface conditions is necessary to properly interpret the torque conversion. Screw piles are a versatile and efficient solution... https://vicdemolition.com.au/piling-melbourne.php
