Subsurface Water Path Detection in Concrete Structures Using Active Thermography

This paper presents a novel technique using active thermography for subsurface water path detection in concrete structures. Active thermography allows full field and noncontact qualitative observation and quantitative measurement of thermal radiation from the surface of a test object.
