Hydrodemolition is the use of a high pressure water-jet to remove concrete. It is a new method of concrete removal which is becoming increasing specified by state Departments of Transportation for bridge rehabilitation work. The technical, financial and contractual aspects of using hydrodemolition are examined and a brief explanation of salt induced concrete deterioration in bridges is presented. Interviews were conducted with state DOT engineers, general contractors, specialty hydrodemolition subcontractors and hydrodemolition equipment manufacturers. These interviews identified problems encountered with using hydrodemolition. Possible solutions to these problems are presented. These possible solutions are based on both suggestions made by the persons interviewed and the author.
