ABSTRACT:
This invention includes repair of an existing underground sump without the need for costly and time consuming excavation. A plurality of liner-forming pieces are placed inside the underground sump to create a liner preferably substantially conforming to the interior dimensions of the sump. The pieces are joined together to form a unitary containment shell by first taping and then using fiberglass cloth and fiberglass resin. A layer of gel-coat is applied to the surface of the shell to create a fluidtight containment chamber within the sump. Some of the liner-forming pieces can have openings formed therein to accommodate the pipe entries corresponding to those in the sump.
