| description | A method for installation of a resin impregnated cured in place liner with an inner impermeable layer (13) is provided. The liner is formed from a resin impregnable material having an impregnable layer bonded thereto. The material is formed into tubular shape with the impermeable layer on the outside of the tube about a tubular forming member and continuously everted into the tubular forming device to place the impermeable layer on the inside. An outer impermeable wrapping can be applied after wetting out the inner tubular member. A pull-in fitting with a steam connection is inserted into the leading end of the liner (101) and the liner is pulled to an installation access (113). Prior to reaching the installation access a receiving canister (115) with steam connection (122) is attached to the end of the liner and pull-in completed. This permits inflation of the pulled in liner with an air curing of the resin with steam. All steaming is done below grade with minimal entry to underground access points. |
