Abstract
A method for repairing pipelines includes impregnating a liner material capable of absorbing a fluid with a fluid uncured and unhardened resin requiring a catalyst for activation to cure and harden. The impregnated liner material is inserted within the pipeline and a catalyst is applied within the pipeline. Resin is then allowed to cure and harden to form a repaired surface for the interior of the pipeline.
