Guide to Underwater Repair of Concrete
|Publication Date:||1 June 2010|
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.
