taking a tubular liner having a first portion and a second portion and impregnating the tubular liner with a light-activated resin;
taking an inversion apparatus having an opening and creating a seal between the first portion of the tubular liner and the inversion apparatus to allow inversion pressure to be communicated from the inversion apparatus to the tubular liner;
inverting the first portion of the tubular liner through the opening under pressure to create an inverted portion of the tubular liner inside the hollow conduit;
attaching the second portion of the tubular liner to a light curing activator;
inverting a remainder of the tubular liner into the hollow conduit so the light curing activator is pulled through the inverted portion of the tubular liner by the second portion of the tubular liner; and
powering up the light curing activator to help initiate curing of the light-activated resin.
