Plastic Coatings and Wraps for New Marine Timber Piling

摘要

The Naval Civil Engineering Laboratory is participating in two long-term studiesof the efficacy of plastic coatings and prewraps for timber piling. Full size polyurethane-coated and polyethylene-wrapped piling have been installed in the Port of Los Angeles. In addition, small wood cylinders have been coated with polyurethane and exposed in the marine environment worldwide. All inspection reports indicate no failures of attachment hardware, no adhesion loss, and no visible borer damage to the plastic wrapped or coated wood after more than 5 years of exposure.
