Abstract
An improved method of rehabilitating a conduit which is in a damaged or deteriorated state. A lining hose, having a resin absorbing inner layer which is soaked with an excess volume of resin, is expanded and shaped to conformingly line a conduit by inverting a calibration hose under fluid pressure inside the lining hose. The calibration hose is comprised of a resin-absorbent layer and an impermeable layer that outwardly adjoins and surrounds the resin-absorbent layer. After inversion, the resin absorbent layer of the calibration hose contacts and adheres to the resin impregnated inner layer of the lining hose and is impregnated in situ with a portion of the excess volume of resin from the lining hose. Upon curing, the calibration hose becomes an integral part of the liner.
