The activity is carried out through the use of diagnostic systems based on non-destructive testing (NDT) conducted using methods that do not alter the material and do not require the destruction or removal of samples from the structure under examination.

They are aimed at the research and identification of defects of the structure itself, whether in concrete, metal or masonry, and are based on ultrasonic and radar tests, infrared thermography, magnetoscopy, radiography, as well as monitoring of structures, including remotely.
