Abstract
A pile for stabilizing soil for building a structure thereon includes a casing having an upper end opposite a lower end, a shaft positioned inside the casing, the shaft having a first end proximal to the upper end of the casing and a second end proximal to the lower end of the casing, wherein the casing and the shaft are substantially coaxial; and a plate attached proximal to the upper end of the casing and holding the shaft inside the casing. Optionally, the plate has one or more grout holes to allow liquid grout to flow into the casing along the shaft, potentially increasing the stability of the pile in soil.
