A multi-layer protective wrap system for wood or metal pilings and poles comprising multiple organic polymer layers (an inner seal wrap, an optional foam conformation layer, and an outer compression shell) secured to the pilings by a bar-and-band system provides resistance to decay, thereby extending the life of pilings/poles in both new and retrofit installations. The 2- or 3-layer wrap system not only extends the life of pilings/poles by protecting them from new infestation by organisms, but also starves existing organisms of the oxygen they require to survive. In addition, because the inventive wrap system seals the piling/poles, it prevents leaching of creosote or other protective coating materials into the environment, reducing the threat of toxicity. This permits industry current standard practice of impregnating pilings with creosote to act as a third or fourth layer inside the 2-3 layers of the inventive wrap system.
