  • Patent number: 11698070
    Abstract: A grouting material delivery and application system for coating the exterior of a collapsed liner with an even distribution of grouting material prior to insertion into a damaged conduit. The apparatus includes a wetout funnel for receiving grouting material to evenly coat the exterior of the liner. The wetout funnel includes opposite walls forming a v-shape with a slot at the bottom of the v-shape and a squeegee disposed at the slot for controlling the coating of grouting material for a uniform covering on the liner as it passes through the wetout funnel. A first ejector pipe having an inflow end and an outflow end for receiving and dispensing grouting material to coat one half of the exterior of the liner. A second ejector pipe having an inflow end and an outflow end for receiving and dispensing grouting material to coat the opposite half of the exterior of the liner.

  • Publication number: 20220082196
    Abstract: An expandable pipe for restoring a damaged pipe is provided. The expandable pipe includes a liner formed of thermoplastic polyurethane, and grout material applied to the exterior surface of the liner. The exterior surface includes a plurality of flared tips and grooves, and each groove is located between adjacent flared tips. The grout material is disposed on the flared tips and in the grooves of the liner. The method used to restore the damaged pipe includes clamping the liner with the grout material on a puller-sealer fixture having a U-shaped cross-section to prevent debris from entering the interior of the liner, and pulling the puller-sealer fixture and liner through the damaged pipe. The grout material expands in volume upon exposure to moisture, ultra violet radiation, heat, and/or ultrasonics, and fills cracks or other imperfections and voids along the interior surface of the conduit, caused by corrosion, erosion, or other circumstances.

  • Publication number: 20180266416
    Abstract: A wetout funnel (82) including opposite walls (88) forming a v-shape with a slot (90) at the bottom of the v-shape and a squeegee (102) disposed at the slot (90) for controlling the coating of grouting material for a uniform covering on a liner (50) as it passes through the wetout funnel (82). A first ejector pipe (104) receives and dispenses grouting material (52) to coat one half of the exterior of the liner (50) and a second ejector pipe (106) receives and dispenses grouting material (52) to coat the opposite half of the exterior of the liner (50). The wetout funnel (82) is mounted on a supporting framework (84) that is positionable over a manhole. The supporting framework (84) has end pieces (92) movable to engage the edges of a liner (50) of different widths.

  • Patent number: 7942167
    Abstract: An expandable pipe (20) for restoring a damaged conduit (22) includes a liner (24) formed of polypropylene material. The liner (24) presents exterior surface (26) defining a plurality of grooves (28) and surrounding a center opening (32). The grooves (28) contain a grout material (30) and provide for controlled placement of the grout material (30). The grooves (28) maintain the placement of the grout material (30) when sliding the expandable pipe (20) into the conduit (22). The grout material (30) includes urethane and recycled fibers (36), and expands in volume upon contact with moisture. The grout material (30) expands to fill cracks in the conduit (22). The grooves (28) also render the expandable pipe (20) bendable in width (W) at the groves for folding and transporting the expandable pipe (20) and for maneuvering around bends of the conduit (22).
