Deep foundations along with Gravity spread support the largest wind turbine generators (4.5 MW turbines currently) in operation. As the turbines are increasing in size, Gravity spreads are approaching the limits of both their capacity and economical limits. Deep foundations are positioned very well for these larger applications due to their design advantages.

Long before the creation of the industrial bread slicer, Corrugated Steel Pipe was invented in the United States. Corrugated Steel Pipe was first used for hydraulic cross culverts in the early 1900s. Since the first culvert application, Corrugated Steel Pipe has been used in many different construction applications.
