Open the CIPO recordAbstract From the Canadian patent
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.
