Corrosion is one of the pathologies that most affects the resistance of reinforced concrete. There are numerous ancient structures still in use affected by corrosion that need proper evaluation and remedial treatment for their maintenance. This work presents a combined methodology by using Ground-Penetrating Radar (GPR) and Infrared Thermograpy (IRT) techniques for the detection and evaluation of corrosion. The combination of these complementary techniques allowed for the identification of corroded areas and moisture, along with inner damages such as cracking and debonding.
