Abstract

The invention provides that a flexible liner is everted into a passageway to line same using liquid under pressure. The liner is fed through an enclosure before it everts and eversion is achieved by pressurization of the liquid in the enclosure. The eversion takes place in steps in that the pressure is periodically relieved and at the same time a fresh length of liner is pulled into the enclosure. When the pressure is restored a length of liner is averted into the passageway. The invention has particular applicability to the placement of liners which although flexible and evertible when being installed, set hard when in position lining the passageways.
