Abstract
The invention provides a method of applying a resin impregnated lining sleeve to a length of passageway surface wherein the sleeve first of all has a carrier tube everted into the sleeve from one end and out of the other end, the carrier tube is re-inverted to draw the sleeve into the carrier tube and then the assembly of carrier tube and sleeve is positioned in relation to the passageway length to be lined and the carrier tube re-everted to position the sleeve on the surface in the required position. The resin is subsequently cured and the carrier tube removed leaving a hard tubular lining shell on the passageway surface.
