ABSTRACT:
A method of relining sewer lines, waterlines or gas lines is disclosed which uses a segmented liner of reduced size relative to the pipe being relined, with the liner being heat/pressure molded to the shape of the pipe being relined. The liner segments are joined by conventional joining techniques, however, the preferred joint is achieved by fusion.
