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.

A composite structural encasement apparatus for bonding to wooden poles for transfer of tensile stresses comprising: (a) a plurality of woven glass fiber mat strips, arranged with the longer dimension substantially parallel to the longitudinal axis of the pole, wherein the percentage of the woven fibers running along the length of the strops and running parallel to the length of the pole is within the range of from 50% to 80% of the total fibers, and wherein the remaining fibers are arranged so that ½of the remaining fibers, from 10% to 25%, are placed at a 45°angle to the longitudinal fibers, and the remaining 10% to 25% percent of the woven fibers are placed at an opposite 45°angle to the longitudinal fibers relative to the first set of angled fibers; (b) a liquid resin for saturation of the woven mat strips which subsequently hardens to form, in combination with the mat strips, a fiberglass encasement repair cylinder for a pole; and, (c) an ultraviolet resistant coating for application to the exterior of the encasement.
