A pipe liner is formed in situ and consists of a reinforced resin impregnated sleeve having an inner plastics sheet, originally in the form of a balloon. The balloon is inflated once the sleeve is in position and while the resin is cured. An epoxy resin is used which binds the sheet to the sleeve so that the sheet forms the inner surface of the liner after curing the resin. |
