Ultrasonic Pule Echo is an advanced imaging technique used to detect defects within any concrete structure.
An ultrasonic pulse is produced by hitting the surface with a small metal object, then shear wave reflections are recorded. A two-dimensional array of transducers captures these reflections and they are then used to generate an image.
Applications of Ultrasonic Pulse Echo
When evaluating large concrete structures, such as thick slabs, thick foundations, beams or columns, conventional Ground Penetrating Radar is unable to provide accurate readings due to interference at larger depths.
Ultrasonic Pulse Echo can be used to map out honeycombing, voids, large cracks or to determine the thickness of reinforced concrete structures up to 2.5m depth.
Xradar™ uses the latest technologies for non-destructive inspections, including the MIRA shear wave tomograph by ACSYS. The advanced instrument has an array of 48 transducers with dry-contact ceramic tips and uses a complex SAFT signal processing to provide a high-resolution image of the internal concrete structure.
The tomograph sends a short pulse through the concrete, then records shear wave reflections in all transducers simultaneously, producing an image or scan of the reflected waves. Our specially trained technicians analyze these images to identify features and/or defects.
