Helical piers, also known as helical anchors, piles or screw piles, are deep foundation solutions used to

secure new or repair existing foundations. Due to their design and ease to install, they are most commonly

used whenever soil conditions prevent standard foundation solutions. Instead of requiring large excavation

work, they thread into the ground. Helical piers are round or square, tubular or bar steel shafts with round

helix plates welded to them.
