<p>A flexible liner (38) includes a back side surface having a number of ribs (46) that project outwardly a distance away from the liner. The ribs each have an enlarged profile configured to provide a strong mechanical lock with an intermediate adhesion layer (44) or carrier that is applied to a surface portion (42) of the underlying substrate (40) needing surfacing or rehabilitation. The liner is installed to surface or rehabilitate a structure by applying a thickness of the carrier to the wall section of the underlying substrate, positioning a back side surface of the liner adjacent the carrier, pressing the liner against the carrier so that the ribs are inserted and completely covered by the carrier, and forming a mechanical lock between the ribs 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.</p> |
