Abstract:
Epoxy crack injection can be used for structural repair of cracks resulting from single occurrence events such as accidental overloads, vehicular impact, earthquake, restrained shrinkage, or excessive thermal differential in mass concrete. Typical applications include foundations, columns, beams, bridge decks, and bridge superstructures. The article describes elements that contribute to the successful and efficient application of epoxy crack injection—capping paste, injection ports, the injection resin, and the delivery system.
