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.
