The Impact-Echo test method is a non-destructive device used to detect defects within the concrete and masonry members. Short duration impactors generate low frequency stress (sound) waves at the concrete surface. These waves propagate into the structure and are reflected by flaws and/or external boundaries. The patterns of propagation and reflection depend upon the structure's geometry and the types of defects present. Multiple reflections of waves between the impact surface and defects or other boundaries give rise to transient resonance conditions which can be identified and used to determine member thickness or the location of the defects. Displacements caused by reflections are recorded by a transducer located adjacent to the impactor. The types of defects that can be determined are: cracks, crack depth, voids, honeycombing, delaminations of concrete, overlays, finishes and estimation of thickness of concrete members.
