Abstract
A method and apparatus for repairing polyolefin structures such as polyethylene piping. The repair method involves a bi-material co-extruded film that homogenously attaches to the poly olefin pipe surface and enables bonding of either epoxy or polyurethane composite material to the overall structure. The method involves surface cleaning with a solvent, attaching the co-extruded film, and applying a heat-activated shrink tape. The surface is heated to activate the bonding process of the film to the PE surface and to create a compressive force via the shrink tape. Once accomplished, the shrink tape may be removed and either a fiber reinforced polyurethane system or a fiber-reinforced epoxy system is applied and allowed to cure.
