Abstract
This invention provides a method for repair for poles which have beem damaged by environmental effects, which is easily transportable, simple to install, and easily adaptable to many classes of poles. The method involves excavating around the pole, cleaning the surface of the pole, pumping a fumigant into the pole, applying a bonding agent to the clean surface, and then applying strips of a composite fiberglass mat and resin to the pole in a controlled manner until a desired casement thickness has been achieved. The repair is completed by application of an ultraviolet resistant coating to the pole.
