  • Patent number: 7267739
    Abstract: The apparatus and method for eliminating ground water infiltration while stabilizing the ground and repairing underground pipe/conduit and connections is taught in this art. The steps are to first inject, under pressure, expandable structural foam in the space adjacent and outside the pipe while blocking any infiltration of the foam into the interior of the pipe, conduit or connection. Concurrently or separately the inside diameter of the pipe is receiving a structural repair. The result is stabilized ground, elimination of ground water infiltration and repair of the host pipe conduit or connection. The invention also teaches a novel method of utilizing a tensioned and compressive support on the outer pipe surface.

  • Patent number: 7073536
    Abstract: An apparatus and method for repairing the juncture or intersection of a first conduit and a second conduit is disclosed. The apparatus includes a main body for transporting and positioning a repair material impregnated with at heat curable resin system or matrix. An inflation device carried within the main body positions and compresses the repair material against the intersection. This includes a portion of the interior of the second conduit and flange portion in the first conduit. The inflation device includes conductive fibers that are electrically conductively heated to effect curing of the resin in the repair material.

  • Patent number: 7052567
    Abstract: The apparatus of the present invention is generally characterized by a heating/inflation module having pressurizable interior and an attached heat curable pre-preg. In particular, an elastomeric, seamless composite is provided that includes a heating element disposed within a thermoset resin matrix. The composite adapted to maintain a consistent temperature profile and an internal air pressure. A first end piece is attached to a first end of the composite and has an air port for communication with a compressed air source, a vacuum port for communication with a vacuum supply source and at least one electrical cable port for communication with a power supply source. A second end piece attached to a second end of the composite. The apparatus further includes a pre-preg removably attached to an outer surface of the composite. The pre-preg includes a structural fiber matrix supporting a heat curable resin.
