  • Patent number: 9074718
    Abstract: An apparatus and method of making a cured-in-place pipe repair to a lateral pipe having an area in need of repair. The method and apparatus use a liner assembly comprising a bladder tube and a liner tube. The liner tube comprises at least one layer of non-stretching material, which includes strands of non-stretching material oriented in the longitudinal direction of the liner tube. The strands allow radial stretching but ensure that the liner tube does not stretch longitudinally, which prevents the liner tube from stretching into a main pipe or past the area in need of repair during use. The liner tube may also comprise second and third layers of a resin impregnable material, such as felt, which surround the layer of non-stretching material such that the liner tube may be impregnated with a resinous material to repair a pipe having an area in need of repair.
