Nondestructive testing (NDT) is a way to examine and evaluate ground, pavement, concrete, bridge decks, and other inaccessible locales. It uses methods such as subsurface interface radar, ground penetrating radar, EM systems and other structural scans in order to deliver an accurate image of areas that are hidden from the naked eye.
As the name suggests, NDT does not result in any destruction or damage. In fact, the techniques that we use do not impact tested areas in any way.
