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.

Protection of wooden articles, such as railroad crossties, against decay or rot is improved through incorporation of borate compounds, such as sodium borate, and a protective coating such as creosote or a resin. Such protection is achieved by placement of a dry borate compound into a hole formed in the wooden article. The hole is then covered, and the borate compound then permitted to migrate and become distributed throughout the wooden article to provide the desired protection. Coating of the thus treated wooden article is conducted either shortly following placement of the borate compound in the hole or at a later convenient time.

This invention is based upon the discovery that activated carbon can be used to sequester polycyclic aromatic hydrocarbons that may be present in asphalt and creosote compositions. The treatment of asphalt and creosote compositions with activated carbon accordingly reduces the level of free polycyclic aromatic hydrocarbons in such compositions by sequestering them therein or removing them from the composition. After being sequestered the polycyclic aromatic hydrocarbons remain trapped in the asphalt or creosote composition, and are not available to the environment during normal processing into useful industrial products. This sequestration reduces the risk of exposing humans and the environment to the polycyclic aromatic hydrocarbons which would otherwise be free to migrate from the asphalt or creosote product during manufacturing and the service life of the product. In other words, the polycyclic aromatic hydrocarbons are absorbed onto the activated carbon and are not available for bioaccumulation from the environment.
