Seventeen years experience of the Gatineau Power Co. indicate that ordinary concrete, reinforced and unreinforced, can be successfully used to repair hydraulic structures. Elimination of leakage prior to surface repair, good bond between new and old concrete, and shrinkage of new concrete during setting to prevent cracking are important. A porcedure for repair is outlined stressing the importance of experienced labor and supervision and briefly describing grouting, selection of materials, design strengths of concrete, preparatin of surface, vibration, forms, curing and joints.
