Abstract
An apparatus and method for repairing a pipe utilizing a pipe lining assembly. The pipe lining assembly may have an inflatable bladder with a first surface opposite a second surface defining a sealed chamber for receiving air. The pipe lining assembly may also have a patch with a first edge and a second edge and is positioned on at least a portion of the first and second surfaces of the inflatable bladder such that the first edge of the patch overlaps said second edge of said patch. The inflatable bladder with the patch positioned thereon is configured such that the first surface of the inflatable bladder overlaps the second surface of the inflatable bladder forming a cylindrical shape.
