It does not take one with too much intelligence to note that our infrastructure is in dire shape. Not only does this include our water & wastewater areas, but also our road and bridge systems need massive help. Deterioration due to environmental issues, water and chemicals that are placed are cause for serious corrosion and erosion concerns. Over the years, a variety of methods have been employed to help with these issues, but all with there own characteristics and problems. As populations grow in centralized areas, not only does this put added abuse on the roads, but also scheduling repairs and time for those repairs, can create nightmares for local traffic. Thick-film spray applied waterproofing systems are not new to the coatings industry and have been successfully used to combat these corrosion and erosion activities. By following coating / lining industry standards, quality inspection techniques during installation and advancements in the product technology, these systems will provide for a high performance waterproofing membrane system for road and bridge application areas. This is a very fast set / cure technology which minimizes road work delays, and offers the ability for complete wear-course applications, offers many advantages to waterproofing work in bridge applications. This presentation will focus on these advancements and performance properties, application and use techniques, as well as potential for robotic type installation that will carry us into the future.
