Helical piles have been used for the first time by Andrew Mitchell, an Irish architect (who was blind) to anchor and build lighthouses on sandy sea beaches, where the constant erosion of the shore would undermine any other type of foundation. He anchored and successfully built large lighthouses, docks, bridges and sea shore structures.
Helical Piles have been used ever since, with an explosion of innovations and versatility and uses and applications after about 1980’. Not surprisingly, even if originally used in Europe, the helical piles have been adopted and re-defined in North America.
Helical piles have been continuously used, therefore, for almost 200 years. Some of the original structures and helical piles, installed in the 1800’, are still standing and in use today.
