Abstract: A system of reinforcing a structural support such as a utility pole in situ includes applying a coating of a curable resin and wrapping a plurality of layers of a fiberglass fabric. The fiberglass fabric is applied in the form of elongated strips having longitudinal and weft fiberglass rovings. The fabric strips are spirally wrapped around the pole while applying a biasing shift to the fabric so that the weft threads are oriented axially to the support and the longitudinal threads extend helically around the support. An electrical resistance heating wire may be included between the wrappings of fiberglass to heat and accelerate curing of the resin.
