Summary:The present invention relates to pile driving systems and method, in particular, to a method for installing pile structures in permafrost ground. The method comprising the steps of rotating a mandrel to form a pilot hole to a pilot hole depth, where friction created by engagement with the mandrel and the permafrost melts liquids in the permafrost, thereby creating a flowable slurry at least partly within the pilot hole; removing the mandrel from the pilot hole; while the slurry is at least partly flowable, arranging at least one pile at least partly within the pilot hole to a pile string depth; and allowing slurry to freeze within the pilot hole at least partly around the at least one pile.
