A method of repairing, protecting or strengthening a utility pole projecting from the ground comprises fitting a compressible elastomeric interlayer around the pole so as to mechanically bind the interlayer to the pole, fitting a sleeve around the pole clad with the elastomeric interlayer, filling the clearance between the interlayer and the sleeve with a flowable hardenable composition essentially free from shrink on hardening, and allowing the composition to harden so as to form a solid core mechanically bonded to each of the interlayer and the sleeve. This method therefore provides an assembly of structural components each mechanically bonded one to the next. |
