Polywater® UPR™ Utility Pole Repair makes it easy to repair woodpecker damage and pole line hardware holes on utility poles. The two-part formula is mixed quickly and injected into the hole through the 8” mixing nozzle. Partially used cartridges can be resealed and reused with a new nozzle. The UPR™ Pole Repair resin and hardener were specially formulated to expand in the pole cavity rather than to just fill.
