ABSTRACT:
An apparatus and method for inflating and curing a resin impregnated liner include a resin impregnated liner lowered into an underground structure so that a portion of the liner extends beyond the structure. The protruding portion of the liner is then sealed. Pressurized air and steam are simultaneously admitted into the liner so that the liner inflates and engages the structure. Air and steam continue to be admitted into the liner for a period sufficient to cure the resin while maintaining the liner engaged with the structure.
