In the construction industry (buildings, bridges) there is a need for fast non-
most commonly to locate targets (Pipes, Re-bars, Conduit,
Fittings etc.) within concrete structures prior to drilling, cutting or coring.
Measuring reinforcements is also performed for static calculations and to detect
corrosion problems and damages. Cracks and voids can also be visualized. The
examinations are not only restricted to concrete constructions; they can also be
applied to reinforced masonry made of natural stones or bricks.
