ABSTRACT LINING OF TUBULAR STRUCTURES A tubular structure, e.g. a tunnel or sewer, is lined by the use of a tubular lining assembly comprising an inflatable tube and curable resin material. The resin material may be light curable, in which case it may surround an inflatable tube of light transmissible material which is cured by the provision of light in the tubular lining assembly when inflated. To position the tubular lining assembly in a tubular structure use may be made of an evaginable carrier. The lining may be laid on the carrier which is then pulled into position, subjected to at least partial inflation, and then evaginated to permit removal thereof with the inflatable lining assembly remaining in the required position in the tubular structure The lining assembly may then be inflated and cured.
