Abstract: A device for protectively encasing wooden piles to reduce marine borer attack, abrasion and other structural damage, comprising: a sheet of flexible plastic wrapped around a pile in a substantially circumferential configuration, where the longitudinal edges of the sheet are placed in an overlapping position; compressible seals attached to both of the horizontal edges of the sheet and to one of the longitudinal edges of the sheet; strap members encompassing the compressible seals of the horizontal edges; a reinforcement member positioned adjacent to the outside longitudinal edge of the sheet; and a plurality of fastening means securing the reinforcement member and the overlapping longitudinal edges to the piling.
