Helical Screw Piles
FLI Structures - Screw Piles
Modern helical steel piling (also called 'helical anchors') is the latest form of a technology developed by Irish engineer Alexander Mitchell for use on screw pile lighthouses. Nearly 200 years ago, his original technology was versatile, relatively inexpensive, easy and fast to use. Nowadays, the same benefits accrue to projects that use this technology.
