Ultrasonic pulse velocity and tomographic imaging technology is increasingly taking centre-stage as a very reliable non-destructive testing method in Concrete industry including quality verification of both in-situ cast and pre-cast concrete structural components (bridges, columns, engineered panels, ring-beams, foundation footings, stitches)
All our testing methodology, data processing and reporting conforms to: ASTM D5882-16, AS/NZS: 2159-2009 and AS/NZS: 2425:2015 industry standards legally recognised within Australia and internationally.
Multi-dimensional imaging options including: [2D/3D], [B-scan, C-Scan, D-Scan can be produced to maximise anomaly illumination and resolution. Results are presented relevant to objectives and finely interpreted for further engineering durability assessment or remediation planning.
Structural Auditing QA/QC
Depending on the specification, we conduct data acquisition and data processing in accordance to EN12504-4 (Europe), ASTM C 597-02 (North America), BS 1881 Part 203 (UK), standard procedures, for evaluating Ultrasonic Pulse Velocity tomography testing on concrete structures through B-scans, C-scans for further engineering analysis.
Grading “Quality of Concrete”
Based on UPV velocity and range interpretations, concrete quality and uniformity can be graded as below:
Using the range (as difference between maximum and minimum), uniformity of quality can be classified as below:
