The lining of a lateral pipe which leads into a main pipe is effected by everting a resin impregnated tubular lining through an elbow in the main pipe. Eversion is by means of fluid under pressure supplied through a pressure pipe. The elbow is held in position by an inflatable bag which is inflated by the said fluid and the bag also seals the lateral/main pipe junction. The bag is such that at least one additional pressure pipe may extend past the seal arrangement so that at the same time as the first mentioned lateral lining is curing, a second lateral may be similarly lined.
