Methods and apparatus are provided for repairing existing structures. A portion of the existing structure is covered with the repair structure. One or more standoffs are coupled to the existing structure to project outwardly away from a surface of the existing structure. One or more cladding panels are coupled to the standoffs by forcing the one or more panels in a direction normal to the surface of the existing structure and into engagement with a standoff connector component of the standoff at a location spaced apart from the existing structure. Curable construction material and/or insulation may be introduced into the space between the cladding panels and the existing structure to provide a repair structure.

The method according to claim 4 wherein the deflecting surface comprises an arcuate surface. 8. The method according to claim 3 wherein moving the panel connector component to an engaged configuration in which the restorative deformation forces of the standoff connector component and the panel connector component at least partially restore a shape thereof comprises causing the mid-section of the deformation-causing portion to move past the transverse opening at least until restorative deformation forces of the resiliently deformable portion at least partially restore a shape thereof, thereby narrowing the transverse opening. 9. The method according to claim 2 wherein the deformation-causing portion defines a transverse opening, and wherein the resiliently deformable portion has: a first transverse dimension at its inward end,a second transverse dimension at its outward end,a third transverse dimension at a mid-section intermediate its inward and outward ends, the third transverse dimension wider than the first and second transverse dimensions when the resiliently deformable portion is in an undeformed configuration;and wherein causing the deformation-causing portion to move against the resiliently deformable portion comprises causing the resiliently deformable portion to pass the transverse opening until the mid-section has reached the transverse opening. 10. The method of claim 1 comprising installing insulation between the panel and the surface of the existing structure. 11. The method of claim 10 wherein installing insulation between the panel and the surface of the existing structure comprises coupling an insulating member to the panel. 12.
