Are you thinking helical piles?
Should you consider a Ductile Iron Pile alternative for higher capacity and reduced risk?
Helical piles are a well-proven technology for underpinning of existing structures and are frequently used for new construction of lightly-loaded buildings with pile capacities typically less than 20 tons. Like any foundation solution, though, there are often situations where alternative technologies may provide greater benefits. For instance, do you need greater pile capacity to optimize your foundations but not sure if you can get there with helical piles? Are you concerned about not achieving the torque requirements or having to extend deeper to generate the required capacity? Will the helical piles “torque out” before getting through an undocumented fill or “spin out” on rock or glacial till leaving you with questions about capacity? We often hear these concerns from design professionals or contractors on projects utilizing or considering helical piles.
