Ultrasonic Pulse Echo Scanning to find voids, honeycombs and delamination in Concrete walls and slabs

Qualitest Canada provides Ultrasonic Pulse Echo Scanning to find voids, honeycombs and delamination in Concrete walls and slabs through its highly qualified Engineers and Inspectors. Qualitest Inspectors perform this Ultrasonic Pulse Echo Scanning services throughout Canada including Toronto, Mississauga, Hamilton, Sarnia, Milton, St. Catharines, Ottawa, Brampton, London, Markham, Vaughan, Kitchener, Windsor, Vancouver, Surrey, Langley, Richmond, Delta, Burnaby, Victoria, Kitimat, Dawson Creek, Kelowna, Kamloops, Edmonton, Calgary, Red Deer, Peace River, Grande Prairie, Fort McMurray, Regina and Saskatoon.

Ultrasonic Pulse Echo is a non-destructive testing (NDT) method for scanning sub-surface targets in concrete elements. UPE methods use acoustic stress waves to study the properties of sub-surface layers, and locate defects by identifying any anomaly of acoustical impedance that is different from concrete. The test method was developed to address practical limitations of the general Ultrasonic Pulse Velocity test, such as the need to access both sides of the concrete element. 

UPE uses stress waves. The principle concept behind the test is measuring the transit time of ultrasonic wave in concrete. A modern UPE instrument consists of an array of piezoelectric transducers that are capable of exciting concrete surface through short-burst high amplitude pulse-high voltage and high current. As the pulse propagates within the concrete, it gets reflected and refracted at the interface of voids, or other internal targets. Any anomaly in acoustical impedance leads the emitted impulse and the reflected stress waves are monitored at the receiving transducer. The signals are analyzed to calculate the wave travel time.

Qualitest Canada provides world-class engineering services in Canada in Welding Engineering, Geotechnical Investigation, Environmental Site Assessment (ESA Phase I, II and III), Construction Materials Testing Services, Non-destructive Testing for Steel and Concrete and Ultrasonic Pulse-Echo (UPE).

Structural flaws cause severe damage and collapse. Ultrasonic Pulse Echo (UPE) is an advanced imaging technique used to detect defects in concrete structures. Ultrasonic testing provides information on the strength and quality of concrete, and it can be used to determine voids, honeycombs, delaminations, pipes, cracks, and defects. The ultrasonic pulse-echo (UPE) technology extends ultrasonic pulse velocity (UPV) applications to objects where access is limited to a single side. Qualitest uses the PD8050 for UPE testing, the World’s Lightest Wireless Ultrasonic Imaging System with Augmented Reality and Artificial Intelligence Capabilities.

Qualitest provides ultrasonic pulse-echo (UPE) testing services for various projects. Our clients include federal and provincial government, contractors, developers, consultants, and owners.

Ultrasonic Pulse Echo can be used to:

  • Location of subsurface defects of concrete such as flaws, cracks, honeycombing, and poor patches.
  • Measurement of thickness of concrete elements
  • Determination of concrete pulse velocity for homogeneity and strength estimation
