Polywater® UPR™ utility pole repair makes it easy to repair woodpecker damage and pole line hardware holes on utility poles. The 2-part formula is mixed quickly and injected into the hole through the 8 in 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. Because UPR™ pole repair expands in the hole, it easily fills irregularly shaped cavities for solid integration with the wood. This creates superior adhesion to the wood grain compared to non-expanding products. UPR™ pole repair hardens just like wood so it is gaffable and will not chip out when climbers' hooks are used.
