Presentation on 14th June 2019 by Isaak Tsalicoglou at the exclusive Henderston Thomas event "NDT of Hidden Defects - A State Of The Art Approach", at The Royal Institute of Britain in London, UK. The state of the art of non-destructive testing applied to civil engineering has in recent years achieved many significant milestones in the field of imaging technologies for the assessment of reinforced concrete structures. The constant improvement of the available electronic components and the increased computational power of consumer-grades mobile devices are among the key factors that drove mature technologies such as Ground Penetrating Radar (GPR) and Eddy Current Testing (ECT) into products delivering new levels of accuracy and usability. At the same time, recent developments of the pulse-echo-based Ultrasonic Tomography (UT) further broadened the range of applications potentially addressed. Still, there seems to be a general lack of awareness in the user community about the real potentials and main limitations of each of the three technologies. The current work focuses on the typical scenarios and the common challenges presented by tasks of embedded object detection (structural details, steel reinforcement, utility network) and flaw detection (voids, cracks, delaminations). The complementarity of the three technologies has been proven through measurements on test blocks and real-life cases. It is noted that the proper combination of technologies naturally results in more efficient workflows, increased positioning accuracy, and a less subjective, operator-dependent interpretation of the testing results.]]>

Presentation on 19th June 2018 by Guido Tronca at GPR 2018 – the 17th International Conference on Ground Penetrating Radar, in Rapperswil, Switzerland. Based on the paper of the same name authored by Guido Tronca, Isaak Tsalicoglou and Samuel Lehner of Proceq SA (Switzerland), together with Gianluca Catanzariti of 3D Geoimaging (Italy). The use of Ground Penetrating Radar (GPR) in structural investigations is based on the detection of features, embedded objects and flaws that cause a reflection of the transmitted electromagnetic wave. Construction types may vary from concrete to masonry and rock and possible targets include metallic reinforcements, ducts, plastic pipes, air voids, as well as the boundaries of the object itself. While a traditional impulse Ground Penetrating Radar (GPR) system uses time-domain measurements of the reflected waves within the investigated objects, a Stepped-Frequency Continuous-Wave (SFCW) system collects data in the frequency domain and converts the data to time-domain data through computer processing. Until recently, the time-consuming calculations associated with the real-time inverse Fourier transforms in SFCW systems limited its application. Thanks to faster processing capabilities available nowadays, this limitation no longer applies to structural GPR. The experimental work on representative concrete and masonry structures presented in this paper shows a systematic comparison of a new SFCW GPR system with traditional impulse radar systems. The results illustrate that SFCW technology combines the highest resolution in the detection of shallow targets, with a very broad detection range, potentially resolving the resolution/penetration trade-off observed in established structural GPR systems. ]]>

Traditional impulse Ground Penetrating Radar (GPR) systems use time-domain measurements of the reflected waves within the investigated objects. A Stepped Frequency Continuous Wave (SFCW) system collects data in the frequency domain and converts the data to time-domain data through computer processing. Until recently, the time-consuming calculations associated with the real-time inverse Fourier transforms in SFCW systems limited its application. Thanks to faster processing capabilities available nowadays, this limitation no longer applies to GPR. The experimental work on representative concrete structures presented in this paper shows a systematic comparison of a new SFCW GPR system with traditional impulse radar systems. The results illustrate that SFCW technology combines the highest resolution in the detection of shallow targets, with a very broad detection range. At the same time, the system is very fast, both in terms of data display as well as data sharing. Therefore, we are concluding that experts, civil engineers and contractors will be able to rely on a higher probability of detection and higher productivity using just one SFCW test system in the future. Proceq GPR Live by Proceq is the world's first and only handheld portable Ground Penetrating Radar for concrete scanning and imaging applications that utilizes Stepped-Frequency Continuous-Wave radar technology and a user-friendly, gesture-based touch interface on Apple iPad, as well as secure cloud-based features enabling collaboration from anywhere, anytime. It provides unparalleled penetration depth (up to 70 cm of dry concrete) and data and image clarity thanks to its ultrawideband radar subsystem. Find out more at http://bit.ly/ProceqGPRLive]]>

Ultrasonic pulse echo testing has been proven to be complementary to other NDT techniques. The leading products by Proceq help to identify defects that are not detectable e.g. with radar or eddy current tests. In particular, deep scanning of walls and linings, finding of deep and second or third layer rebars and tendon duct analysis deliver unrivalled results compared to other techniques. However, the case studies presented in this paper also highlight some of the issues that need to be looked at in order to increase the value of on site pulse echo testing. Scanning speed has been one key issue that has been partially addressed through the introduction of real time B-scan imaging incl. an immediate onboard feature to create panoramic scan images out of individual scans. It has also been recognized that 3D imaging and variable slicing of the scan data help a great deal in visualizing the structural features. A few recent advancements have been laid out in this paper, however, the authors realize that further steps are needed to fully explore the power of this NDT technology. One further step in this is use artificial intelligence positioning systems and improved image stitching to expedite and ease on-site usage of the system. Also an onboard data interpretation system is underway and ready for release to the markets, which can be particular helpful when the initial test reports are already created on-site. Finally, an on-site 3D analysis will be introduced into the next generation of instruments as well to bring ultrasonic pulse echo testing of concrete structures to the next level. ]]>

When using ultrasonic flaw-detection equipment, it is essential that the performance characteristics are known. Calibration should be repeatable and operator-independent, especially in situations where flaw growth is being monitored at discrete intervals. In order that changes due to wear, component temperature or other causes may not go un-noticed, the calibration measurements should be repeated at frequent intervals. Probes, especially, must be checked before commencing and after completing critical work to ensure the validity of the entire measuring results. Prior to the release of the ISO 19675:2017 calibration block, the techniques to calibrate and assess these performance characteristics for an ultrasonic phased array inspection were performed in a variety of ways in different parts of the world. Existing calibration blocks did not allow checks for all the necessary phased array code and standard requirements, therefore adapted blocks for calibration procedures were implemented by a select minority of expert engineers. The ISO 19675:2017 block allows for all ultrasonic testers, worldwide, a simple and consistent tool and allows for widespread adoption of phased array ultrasonic inspections across many industries. It was also designed to allow to check probes as specified in other ISO standards. the new ISO 19675:2017 is a flexible and simple tool for calibrating combined equipment and it offers more than the ISO 2400 block for both conventional and linear phased array setups. This calibration block will become a useful tool that is used in industry for calibration of ultrasonic inspections. The workflow structures and calibration wizards in modern portable flaw detectors have been designed for easy, repeatable calibration. Proceq’s own developed broadband probes show greater sensitivity than traditional PZT transducers, the necessary gain to detect a 1.6 mm hole in the ISO 19675 block was over 9 dB lower, however further development of different probe types using this proprietary crystal is necessary to expand the application and usages in the field of NDT. ]]>
