A foundation pile, in particular offshore foundation pile, comprising a circumferential foundation wall extending in the longitudinal direction, wherein the foundation wall is bounded on the lower side by a lower-side end face and on the upper side by an upper-side end face, wherein the foundation wall is formed from a mineral building material, wherein in the foundation wall a plurality of channels extending substantially collinear to the foundation pile axis is formed, running substantially collinear to the foundation pile axis, wherein at least a part of the plurality of channels has an upper opening on the upper end face in each case.

Extensible shells and related methods for constructing a support pier are disclosed. An extensible shell can define an interior for holding granular construction material and define a first opening at a first end for receiving the granular construction material into the interior and a second opening at a second end. The extensible shell can be flexible such that the shell expands when granular construction material is compacted in the interior of the shell. A method may include positioning the extensible shell in the ground and filling at least a portion of the interior of the shell with the granular construction material. The granular construction material may be compacted in the interior of the extensible shell to form a support pier.

A system for positioning and anchoring columns. The system includes a positioning template having a first frame configured to support horizontal panels, jacking mechanisms for leveling the horizontal panels, a first opening defined by the horizontally aligned panels configured to guide a sleeve when driven downward below grade level through the first opening, and a tubular sleeve for passing through the first opening and for receiving a second frame. The second frame includes frame members defining a second opening on each end of the second frame and a plurality of elongated bars spanning between the first end and the second end. The second frame is for guiding a pile when driven downward. A pile having a first end and an opposing second end is configured for receiving a connecting tube of a column. A column having a connecting tube is to inserted into the pile's first end.
