Helical piers have a fascinating history that dates back to the early 1800s. The concept originated with Alexander Mitchell, an Irish engineer who, despite being blind, developed these piers to support lighthouses and docks in weak and marshy soils. This innovative approach addressed the challenges of constructing in difficult terrains, where traditional digging methods were ineffective. The use of helical piers saw a decline in the mid-1900s due to the lack of suitable machinery and measurement techniques. However, the last two decades have witnessed a resurgence in their popularity, thanks to advancements in technology and a better understanding of their applications.

The Evolution of Helical Piers: A Historical Perspective

Helical piers have a rich history that dates back to the early 1800s. Their inception can be attributed to Alexander Mitchell, an Irish engineer who was also blind. In 1833, Mitchell used these ingenious devices to support lighthouses and docks on weak, marshy soils. Initially, their primary function was to provide stability in challenging landscapes where traditional digging was impractical. Over the decades, their usage saw a decline, primarily due to the heavy machinery required and the complexity of installation.
