Abstract: A protective covering strip is constructed of a flexible, waterproof material, such as rubber or a plastic compound, and is configured to fit over the upper and/or side surfaces of an elongated wooden member. The strip is formed as an inverted channel and has a length and width substantially corresponding to the length and width of the wooden member to ensure a snug fit. A plurality of longitudinal ribs are provided along the length of the strip. The side portions of the strip may be beveled outwardly to speed water runoff. In use, in the construction, for example, of a wooden deck, covering strips are secured to the top and/or side surfaces of the posts, joists and girders to separate and prevent any direct contact between the post/girder, girder/joist and joist/wooden flooring joints. The covering strips prevent the collection of water in the joints between the respective wooden members, and also prevent water seepage into nail holes formed during the assembly process.
