The Impact Echo (IE) method is used for rapid flaw detection and thickness evaluation of concrete and masonry structural materials.
- Applicable for plate-like objects such as slabs, walls, columns, mat foundations, beams
- One-sided testing
- Flaw location and depth
- Thickness profiling without the need to drill, core or excavate
A variation of the impact echo principle is the Impact Echo Scanning (IES) method.
- Patented technology of a rolling transducer and automated impactor for near-continuous IE testing
- Fast-acquiring IE testing (1000 points/hour)
- Best for high resolution imaging of large areas for internal concrete conditions
- Example applications: slab thickness profiling and flaw detection, pavement testing, location of ungrouted sections of post-tensioning ducts
- Read a paper on the IES, as applied to PT duct void location
