Abstract: An apparatus and method is provided for lining the wall of a manhole. The apparatus may include a liner assembly. The liner assembly includes a bladder, a liner holding device, and a liner. The bladder comprises a first end positioned near an opening of the manhole, and a bladder body positioned in the manhole. The liner holding device is positioned at least partially above the opening of the manhole. The liner includes a first end operably connected to the holding device, and a liner body positioned at least partially surrounding the bladder in the manhole. The liner holding device is adapted to feed a portion of the liner body into the manhole during expansion of the liner body.

Abstract: A method and system for dispensing a material through a delivery apparatus is provided. The material initially comprises or is manipulated to comprise a low viscosity. The material either can comprise a curable material or can comprise initiators, which can be activated to raise the viscosity at a later time and position. The low viscosity material is moved through the delivery apparatus for a relatively long distance using low energy. Upon nearing an end use application, the material and/or initiators can be activated by a curing agent, such as a light or heat source, such that the viscosity of the material be raised prior to the end use application thereof. Therefore, the present invention provides a method and system for moving a material normally having a higher viscosity a long distance requiring lower energy and pressure.
