✦ Synopsis

An apparatus and method for forming or repairing a well-bore casing, a pipeline, or a structural support is disclosed. An expandable tubular member is radially expanded and plastically deformed by an expansion cone that is displaced by hydraulic pressure. Before or after the radial expansion of the tubular member, a sliding sleeve valve within the apparatus permits a fluidic sealing material (which can be hardened) to be injected into an annulus between the expandable tubular member and a pre-existing structure.
