Abstract: A pile driving system and method of operation for driving pile casings formed of a material which is a composite of fiberglass and a resin matrix. The pile casing is sleeved on a mandrel which receives driving forces from a hammer. The driving forces are directed from the mandrel into a boot plate which penetrates down as it makes a hole in the soil. The pile casing rides down with the mandrel, and as the depth increases additional sections of pile casings and mandrel segments can be added. Trapping devices are provided for trapping the pile casing relative to the mandrel so that a portion of the driving forces are directed into the pile casing.
