A pipe lining assembly and a method for plugging a pipe line utilizing a pipe lining assembly are provided. The pipe lining assembly includes an inflatable bladder having a first end and a second end defining a cylindrical body, and a patch folded in a hat like shape disposed over the first end of the bladder.
