Abstract

See full text

The present invention is a method for rehabilitating, repairing, and replacing manholes and connected sewer lines. In some embodiments, a compressed liner is inserted through the manhole access hole or the connected sewer lines. Prior to insertion, the liner may be cut and/or folded to be compressed to a size that can fit through the manhole opening or the sewer lines. Once inserted in the manhole or sewer lines, the liner should be expanded, and if necessary, bonded together with a resin along the separation line. Next, a bonding material may be injected between the liner and a surface of the manhole or sewer line to seal any cracks or fissures in the brick or concrete wall and to seal the liner against the existing manhole or sewer line to improve structural integrity and longevity. A new corbel may then be installed and bonded to the liner.
