1. A pile casing comprising:
a hollow that extends through an entire length of said pile casing, wherein said pile casing is manufactured of a first material selected from the group consisting of a polymer material and a composite material comprising a polymer material and at least one of glass fibers, carbon fibers, steel fibers and wood, and a cross-section of said hollow defines a plurality of engagement structures in said hollow, at least one of said engagement structures extending along an entire length of said hollow and having a shape that, when engaged with a counterpart structure of a counterpart shape, inhibits disengagement of said counterpart structure from said engagement structure in a radial direction of said hollow. |
