In Florida, the depth to which coastal helical piles need to travel depends on numerous factors, including the soil type, load capacities, and varying site conditions. In typical installations, screw piles are engineered to be put into a depth where they can support the vital load demands. The distance at which screw piles are installed is essential, as the load-bearing helix plates are what takes the weight of the structure and conveys it into the soil. The helical pile, with multiple helix’s, is positioned along the pile shaft, which lets it encounter solid soil deep below the surface. The screw piles depth may fluctuate from a minimum of 14 feet to over 70 feet, depending on the engineer design requirements. The conditions will specify a torque and load capacity in which the pile must hold.
Our screw piles are installed with a digital torque indicator which dictates applied torque capacity. If the desired engineered capacity has not been attained the helical pile must be driven further into the ground by adding additional extensions. The extensions shall travel deeper until the soil condition is solid enough to meet this engineered requirement.
