Abstract
A foundation pile, has at least one tensioning tendon which is elongated. A tubular wall forms a hollow conduit located around the at least one tendon so that a space remains between the tensioning tendon and the hollow conduit. A structural tubular element is located around the hollow conduit and composed of a non-metallic material. A tubular layer of a composite material is located around the structural tubular element and connected with the latter. A friction coating applied on an outer surface of the layer of composite material.
