1. An integrally formed extruded pile comprising:
a pipe having an outer surface, an interior surface, an outer width, measured from a first point on the outer surface to an opposite point on the outer surface, of at least four inches, and a length from a first end to an opposite second end; and
a plurality of intersecting walls within the pipe, the intersecting walls being coextensive with the pipe and having wall surfaces, the intersecting walls intersecting the pipe at the interior surface; and
the extruded pile being comprised of a blend of a thermoplastic and chopped strand glass fibers, the chopped strand glass fibers in the extruded pile including intact pellets of pelletized chopped strand glass fibers and distinct strands of chopped strand glass fibers; and
a co-extruded cap stock covering the outer surface of the pipe, and the cap stock not containing chopped strand glass fibers, the co-extruded cap stock having an exterior surface; and
the coefficient of friction of the interior surface and wall surfaces being greater than the coefficient of friction of the exterior surface of the cap stock in soil.
