Helical Piles

Helical piles, also known as helical piers, are constructed using steel shafts with helical flights and offer a cost-effective solution for deep foundation support stabilizing.

The shafts are advanced to bearing depth by twisting them into the soil while monitoring torque to estimate the pile capacity. A detailed understanding of the subsurface conditions is necessary to properly interpret the torque conversion. After reaching design capacity, the tops of the shafts are connected to the structure’s foundation.

Helical Piles are a viable alternative to driven piles and are ideal for use in shallow foundations or limited access areas. Helical piling has been used in many applications including elevated walkways, bridges, boardwalks, piers and more. Helical pile installation is usually not affected by weather conditions and can even be removed and relocated if necessary. Concrete can be poured immediately because there are never any excavation or soil disturbance issues.

Chesterfield Associates has provided many clients with cost effective solutions for helical piling projects. These solutions have allowed for faster installations without any vibration concerns.
