Claim:
A pipe repair process, the method comprising the steps of: enlarging and shaping a perforation of a pipe wall to a sized hole having a diameter for receiving a blind rivet, the blind rivet comprising: a body having a tubular section, a flange formed about a perimeter of a flange end of the body, and a tubular end seal spanning across and contiguous about a distal edge of the tubular section providing a seal at a distal end of and enclosing the tubular section, and a mandrel comprising a mandrel shank having a body expander at an expansion end of the mandrel, wherein the mandrel is assembled through the tubular section positioning such to expand a diameter of the body when the mandrel shank is drawn away from the body; inserting the tubular section into the sized hole; securing the blind rivet into the sized hole by mechanically deforming the rivet body by drawing the mandrel away from the rivet; and forming a watertight seal between the blind rivet and the pipe.
