  • Patent number: 10683959
    Abstract: A method and assembly for sealing an opening in a pipe wherein the opening is a damaged/cracked section in a length of pipe or the junction between a main pipe and a lateral pipe. The assembly includes a sealing member attached to a positioning tube such as preliner. The sealing member is combined with the preliner so that when the assembly is positioned in the main pipe, the sealing member corresponds with the opening. The sealing member is sized such that it extends along the main pipe on opposite sides of the opening. A mainline liner is installed within the preliner. In some embodiments, after the mainline liner cures and hardens, a cutter is used to cut an opening in the mainline liner, preliner, and sealing member to reinstate service to the lateral pipe. The sealing member remains in place around the periphery of the lateral pipe junction to act as a water stop at the opening.

  • Patent number: 10472931
    Abstract: A system and method for performing a flexible liner inversion out from a low-permeability borehole. A flexible liner may be installed by eversion down a subterranean borehole to selectively seal the borehole. Such a liner may be removed from the borehole by inverting it up the borehole. Water is added into the borehole beneath the lowest end of the liner, to permit or facilitate inversion of the liner. Water is allowed to flow from the interior of the liner to the borehole space beneath the liner, thereby raising the pressure in the unsealed borehole beneath the liner, and thereby allowing the liner to be further inverted upward. By allowing water to flow from the liner interior to a borehole volume beneath the liner, the need for a long vent or pumping tube is avoided.

  • Patent number: 9982828
    Abstract: The method for rehabilitating a damaged section of a pipe without a need for a resin absorbent liner is provided. The method includes pumping a low viscosity material towards a damaged section of pipe and changing the viscosity prior to dispensing of the material. For example, the material may be partially cured prior to dispensing. The partially cured or higher viscosity material is compressed between an inflating bladder and interior wall of the pipe, and the material that is allowed to fully cure. The bladder either can then be removed from the pipe or could be allowed to maintain in the pipe providing a new interior surface for the repaired pipe.
