WHAT IS ULTRASONIC PULSE VELOCITY (UPV) CONCRETE TESTING?
Ultrasonic Pulse Velocity (UPV) testing is a non-destructive method used to assess the internal condition of concrete. The process involves sending high-frequency sound waves through a concrete element and measuring the time it takes for the pulse to travel between transducers. The speed of the pulse provides insight into the concrete’s density, strength, and uniformity.
UPV testing is widely recognized for its ability to:
- Identify cracks, voids, honeycombing, and areas of poor compaction
- Compare the relative quality of concrete across different structural elements
- Provide supporting data for structural evaluations, retrofits, and foundation reuse
- Reduce the need for invasive testing by offering reliable, real-time results
THE ULTRASONIC PULSE VELOCITY TEST METHOD
- ASTM C597
- ASTM C597
Compressive strength is measured by breaking concrete specimens in a compression-testing machine. Compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi).
OUR UPV Concrete Testing Process
ASTM Ultrasonic Testing of Concrete
At Specialized Testing, our UPV testing process uses non-destructive ultrasonic equipment to evaluate the internal condition and uniformity of concrete. By transmitting high-frequency sound waves through the structure and measuring their travel time, we can detect variations that indicate cracks, voids, honeycombing, or fire damage. This method provides a fast, reliable assessment of concrete quality without damaging the structure, helping engineers determine strength, durability, and the need for further investigation or repair.
- ASTM C39
- ASTM C42
- ASTM C78
- ASTM C109
- ASTM C140
- ASTM C1314
When our technician arrives on-site, the process begins with a thorough visual inspection of the structure to identify areas of concern and determine the most effective testing locations. Based on this assessment, we establish the scope of testing and prepare multiple points where ultrasonic pulse velocity measurements will be taken. During testing, transmitter and receiver sensors are carefully positioned on opposite sides of the concrete surface at precise distances to allow accurate wave transmission. Conductors are used to ensure consistent contact and signal flow, with spacing adjusted to the geometry of the element being tested. Our team uses state-of-the-art ultrasonic equipment operated by highly trained, certified staff to deliver precise and reliable results, ensuring that the concrete’s condition and integrity are properly evaluated before any repair or reuse decisions are made.
