Bridge Deck Analysis

Road salts, water, extreme temperatures, and overloading all take their toll on concrete bridge decks. In 2006, The Federal Highway Administration indicated that 26% of U.S. bridges needed major repairs or were not designed to handle current traffic levels. So what do you do if you are one of the many bridge owners with a deficient bridge deck?

Using Ground Penetrating Radar (GPR), Atlantic Subsurface Imaging can quickly determine the condition of your aging bridge deck to help you plan for future rehabilitation. In addition, Bridge Deck Analysis can also be used to verify new construction. A detailed report with graphical and empirical data detailing the problem areas of your deck will take the guesswork out of planning your rehabilitation strategy. Best of all, GPR is fast, safe, accurate and non-destructive.
