A flexible liner is formed from a resilient material and includes a back side surface having a number of outwardly projecting members that extend a distance away from the liner. The flexible liner is in sheet form for rehabilitating surface sections, and is not in the form of a tube to cover an entire surface diameter. The outwardly projecting members each have a head enlarged profile configured to provide a strong mechanical lock with a carrier that is injected within an annular space disposed between the liner back side surface and the underlying substrate surface in need of surfacing or rehabilitation. The liner is positioned adjacent the structure surface by use of a collapsible, expandable form, and a carrier is injected within the annular space disposed therebetween so that the liner outwardly projecting members are completely enveloped by the carrier. The carrier is cured to form a mechanical lock between the outwardly projecting members and the carrier. The carrier cures to form a strong bond with the surface of the underlying substrate but not with the back side surface of the liner.
