What are helical piles?
Helical piles are also known as helical piers, screw piles, and helical anchors. They are deep foundation elements used for new construction, to underpin existing foundations, lift settling structures, and provide structural support. Tension and compression capacities range from 40-80 tons.
COMPONENTS OF A HELICAL PILE
HELICAL PILE INSTALLATION
Helical piles and foundation repair
Helical piers are often used to repair any type of foundation that has settled, rotated, or cracked with the process of foundation underpinning.
FOUNDATION UNDERPINNING PROCESS
Helical piers are installed adjacent to the settled structure and are attached to the foundation with steel underpinning brackets. A manifold hydraulic jacking system uniformly lifts the foundation to its original position by pushing down on the piers and pressing up on the brackets which are attached to the structure.
Helical anchors and earth retention
HELICAL TIEBACK ANCHOR INSTALLATION
Similar to the installation of a helical pile, helical tiebacks are screwed into the soil horizontally and are usually terminated with some type of waler beam. Helical tiebacks rely on tension strength and skin friction with the soil. Neat cement grout is often added to supplement the tension/uplift capacity of helical tieback anchors.
