A lining comprising a resin absorbent tube having on the outside a fluid impermeable membrane everted into the passageway to line same using fluid pressure. The resin absorbent material is soaked in resin by trapping a quantity of resin in the lining before it everts in the passageway, and the resin is cured after the lining is everted into the passageway surface, preferably by a curing means following the everting lining along the inside of the passageway.
