  • Protective guard means for wood piling and a method of installing same under dry working conditions
    Patent number: 3999399
    Abstract: Protective guard means for wood piling which includes a one-piece waterproof seamed plastic jacket for water-contacted portions of the piling from a level below the lowest water level to a point above high water level. The jacket is gathered snugly about and cinched to the piling and preferably includes a liner immune to attack by wood preservative chemicals. An arcuate guard strip of tough, high impact strength sheet resinous material is clamped to the exterior of the plastic jacket for that portion of the piling likely to be struck, buffeted or abraded by water craft and floating objects. The described protective guard means are assembled to the piling before the piling is driven and preferably above water level and under dry working conditions without need for divers or underwater equipment.
