Abstract:
A United States railway company uses a unique process of inspection and underwater grouting as a part of its railway bridge preventive maintenance and safety program. An Ohio firm of maintenance speciaists trained and qualified to use diving gear uses its patented bagpipe grouting procedure to install grout-filled nylon mesh bags around concrete bridge pier foundations to stabilize the piers against the erosive effects of silt-laden river currents.
