Abstract
A pile is comprised of a pipe, i.e., a tube or hollow cylinder of annular cross-section, with a coextensive internal reinforcement comprised of a plurality of intersecting walls forming a plurality of vertices. Each vertex intersects the pipe. Adjacent intersections are evenly spaced around the annular cross-section. The pile is comprised of a blend of PVC and 20 to 50% (pbw) chopped strand glass fibers. A groove is cut into the pile adjacent to an end for frictional retention in a sea bed.
