DESIGN REQUIREMENTS A. Shaft Type of Helical Pile/Anchor There are 4 basic types of helical piles available. You can customize your version, adding any of the provided additional modules! A helical pile is a straight piece of pipe welded with flights (steel plates). The helical plates welded to the shaft of a helical pier are designed to pull the pier into the soil when the pier is installed. • A helical anchor/pile consists of one or more helix-shaped bearing plates attached to a central shaft, which is installed by rotating or "torqueing" into the ground. Helical piles, also known as helical piers or screw piles, are constructed using steel shafts with helical flights of various sizes to suit the site specific ground conditions. This company provides helical piles, foundation settlement repair, concrete restoration, shotcrete, pressure grouting, and slabjacking for residential and commercial buildings. Helical piers can stabilize settling foundations by connecting footings and walls to solid, load-bearing soils.
