ABSTRACT:
A tubular plastic shell, with an overlapped longitudinal seam and longitudinally extending interior pockets that form exterior ribs, encircles a wooden pole or piling in an area to be protected. A foamed adhesive between the shell and pole fills and seals the surface of the pole beneath the shell, adheres the shell, and provides a supporting cushion for the shell that inhibits cracking or puncturing from impact. Longitudinally spaced ends of the shell beyond the pockets tightly encircle the pole to prevent escape of the adhesive as it forms during application. Ribs at the overlapped seam nest into pockets to retain the shell tightly about the pole during expansion of the adhesive. Where impact or abrasion are not anticipated, the shell can be used as a carrier and mold for forming an adherent foamed sealant layer or covering about a pole and then be removed.
