Apparatus and method for repairing the junction of a sewer main and lateral pipe
The present invention is an improved method and assembly for repairing a pipe or the junction of two pipes, such as sewer pipes. The assembly includes a launcher device having a launcher device body, a launcher device opening disposed on the launcher device body, and a main bladder substantially surrounding the launcher device body. The main bladder includes an opening that substantially aligns with the launcher device opening. 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 is attached to the exterior of the launcher device body. 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; inflating the bladders; pressing the liner against the pipe; and allowing the resinous material to cure and harden.
