Helical piers, also known as screw piles, have an intriguing history that dates back to the early 1800s. The concept was pioneered by Alexander Mitchell, an Irish engineer who, despite being blind, revolutionized construction techniques. Mitchell initially used helical piers to stabilize lighthouses and docks in weak, marshy soils where traditional digging was impractical. Over the years, the use of helical piers waned but experienced a resurgence in the last two decades, driven by advancements in technology and machinery.
