Abstract: The in-situ rebuild method comprises roughening by a roughening technique a surrounding inner or outer surface to be treated around a defective section of a pipe or containment structure, applying one or more layers of a self-adhesive fiber sheet onto the roughened surface to be treated, encapsulating with a vacuum bag the one or more layers of the self-adhesive fiber sheet laying on the surface to be treated, creating by means of a vacuum system a low pressure into a space between the vacuum bag and the surface to be treated, injecting by means of an injection system an impregnation curable resin into the mentioned space, stopping the injecting and letting the impregnation curable resin to cure thereby forming a composite rebuild laminate on the surface to be treated surrounding the defective section, and disconnecting the vacuum system and the injection system and removing the vacuum bag.
