Japanese Patent JPH10503134
Kind Code:
A
Abstract:
A flexible liner is formed from a resilient material and includes a back side surface having a number of ribs 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 or carrier that is applied to a surface portion of the underlying substrate 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 is formed from a resinous material that has good adhesion properties and that displays good chemical and/or corrosion resistance when cured. 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. The ribs are disposed within the carrier and are mechanically lock therein by curing action of the carrier.
