The invention provides that in the lining of a surface, such as the surface of a passageway with a lining sheet, in which case the lining sheet is a tube, the lining sheet is placed on the passageway surface and is cured with laser light energy applied by a fibre optic harness (having multiple ends), which is pulled along the inside of the passageway, and wherein the lining sheet comprises a relatively inert resin requiring a high temperature (of the order of 170 DEG C) to cure, which is either a) transparent to the light energy, but which contains matter which reacts to the light energy and is heated up to said high temperature thereby, in turn to heat the resin and effect its cure; or b) pigmented so as to react with the laser light to generate said high temperature. |
