Screw piles/screw piling and helical (screw) piles --Introduction


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.
