Abstract: A piling which can be embedded into a sand or mud bedding beneath a body of water and which includes a cylindrical body portion having a smooth exterior surface; the body portion being made of a synthetic material, preferably a polyvinyl chloride material. A longitudinal bore extends through the body portion to permit introduction of a fluid under pressure thereby facilitating the sinking of the piling into the bedding. After the piling is embedded, the bore is covered, thereby providing a space for resisting the forming of a vacuum in order to prevent loosening and releasing of the piling from the bedding.
