Concrete Ultrasonic Pulse Velocity Test.

Our Services

Non-Destructive Evaluation of Concrete Quality and Integrity

Ultrasonic Pulse Velocity Test (UPV) is a pivotal non-destructive testing (NDT) technique employed to assess the uniformity, quality, and internal integrity of concrete without causing any damage. By measuring the velocity of ultrasonic waves traversing concrete, the test offers valuable insights into its density, elasticity, and the presence of internal defects such as cracks, voids, or honeycombing. At Global Lab, the UPV test is conducted in accordance with the Standard IS 516 : Part 5 : Sec 1, IS 13311 Part-1 facilitating the reliable diagnosis of both in-place and laboratory specimens for construction, maintenance, and quality assurance purposes.

Why UPVTMatters.

Detects Internal Defects & Voids

The test identifies hidden flaws such as cracks, honeycombing, or delaminations that are not visible on the surface, ensuring early detection of potential structural issues.

Evaluates Concrete Uniformity & Quality

By comparing pulse velocities across different locations, engineers can assess the overall consistency and compactness of the concrete used in a structure.

Estimates Elastic Properties & Strength

UPV results can be correlated with the dynamic modulus of elasticity and the quality of concrete, providing valuable insights into material behaviour.

Non-Destructive and Reliable for Existing Structures

Since the test causes no damage, it’s ideal for quality control, structural health assessment, and post-repair verification of bridges, tunnels, and buildings.
