The present invention is directed to methods and assemblies for repairing pipes or pipe junctions. The assembly includes a launcher device having a launcher device with a main bladder substantially surrounding the launcher device body. The assembly further includes an absorbent liner and a lateral bladder having a tubular lateral bladder body portion and a flange portion. The flange portion of the lateral bladder may be attached to the exterior of the launcher device body. The lateral bladder may include an open end, a closed end, and an opening or hole proximal the closed end. A method of using the assembly includes impregnating the liner with resinous material, inserting at least a portion of the liner into the lateral bladder, pressing the liner against the pipe, and allowing the resinous material to cure and harden. |
