This system is designed to determine the condition and thickness of concrete, wood, stone, and masonry structural members when voids, honeycomb, and/or cracks are suspected. IE investigations can also be performed to predict the strength of early age concrete if the member thickness is known. Lastly, the IE method will provide information on the depth of a flaw or defect, in addition to mapping its lateral location and extent. An advantage of the IE is that only one side of the structure needs to be accessible for testing. The Freedom data PC provides stress-wave based NDT condition evaluation of concrete, masonry, asphalt, wood and other construction materials, as well as seismic testing of soil and rock. This platform provides complete data processing capability for all test methods.
