Four large hollow concrete pilings, cracked by an accident in handling during manufacture, have been completely and permanently repaired by epoxy crack injection. The structural repair both eliminated a possible construction delay and saved the manufacturer the cost of remaking the pilings. The cracks were first coated with a sealer, leaving open ports ever 6 to 8 inches. Epoxy injection takes place when the injection gun nozzle is placed against an open port of the crack and activated. When adhesive appears as the next open port the gun is removed and moved to that port. A feature of the method is the adhesive penetration is total and usually not limited by crack depth. When the epoxy injection was completed, the temporary sealer covering the cracks was removed, leaving the surface unmarred.
