Abstract: A plastic jacket that is used for repairing underwater or on ground support piles that have corroded by the wave action at the water line, by a tidal zone or natural salty air corrosion, respectively. The jacket consists of a cylindrical wall having annular corrugations on its exterior surface. The cylindrical wall has a longitudinal cut along its length to exhibit two opposing edges. A seal is placed between the opposing edges. Opposite from the longitudinal cut there is a V-shaped through the corrugations to the cylindrical wall to create a living hinge in the plastic material of the wall. Banding is provided to pull the opposing edges into a tight relationship and trapping the seal there between. The V-shaped cuts enable the jacket to be opened and placed around a damaged pile in spite of the corrugations which prevent such an opening. It is preferred that the material of the jacket be made of a transparent material.
