Total Surface Selective Removal of Concrete Utilizing Hydrodemolition
As an engineer with the Missouri Department of Transportation, spending over 26 years in field bridge maintenance and inspection, I have had the chance to participate in the evaluation of many products and processes related to bridge repairs. Without question though, one of the most fascinating processes I have encountered is the process of hydrodemolition, especially as it relates to bridge deck restoration. It is a process that has unlimited potential in changing the course of bridge deck preservation and it has in numerous states already. The technology is believed to have first been developed for use on bridges in Italy in the early 1980s, but it was the Swedish National Road Administration (SNRA) who aggressively pursued it as a process in the mid-80s for addressing their aging and rapidly deteriorating concrete structures. The process was introduced into the United States in 1979 on bridge deck patching type projects, but has continued to evolve through the years, especially as it is used in bridge deck restoration. In particular, a process known as fast track hydrodemolition is now a very practical and cost effective process to attack aging bridge decks and prolong their life. Hydrodemolition is a method of removing unsound concrete that utilizes direct impact of a water jet through a combination of pressure and water flow.
