ABSTRACT:
A lining and method for in situ rehabilitation of a pipe. The lining includes a tubular shaped resin impregnated composite having a conductive layer surrounding an inflatable bladder. The method includes the steps of positioning the lining within a pipe section, inflating the bladder until the lining is in contiguous contact with the interior of the pipe and inducing an electric current through the conductive layer to resistively heat the lining and cure the impregnated resin.
