This guide covers the repair of concrete structures in the splash zone and underwater portions of structures located in lakes@ rivers@ oceans@ and groundwater. Concrete deterioration@ investigation and testing procedures@ preparation@ materials and methodology@ and inspection procedures are described. Design considerations and references for underwater repair of concrete bridges@ wharves@ pipelines@ piers@ outfalls@ bulkheads@ and offshore structures are identified. Scour repair@ however@ is not included in this guide. One option for repairing underwater structures is to construct a cofferdam around the structure and remove the water inside the cofferdam. Concrete repairs can then be installed in the dry@ as discussed in ACI 546R.
