Non-Destructive Evaluation of Concrete Quality and Integrity

The Ultrasonic Pulse Velocity (UPV) Test is a key non-destructive testing (NDT) technique used to evaluate the uniformity, quality, and internal integrity of concrete without causing any damage. By measuring the speed of ultrasonic waves passing through concrete, the test provides valuable insight into its density, elasticity, and the presence of internal flaws such as cracks, voids, or honeycombing. At Global Lab, the UPV test is performed using precision-calibrated digital pulse velocity meters, enabling 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.A low water permeability significantly reduces chloride transport, preventing corrosion of embedded steel reinforcement and ensuring long-term durability.

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.Concrete with low permeability minimizes sulfate ingress, maintaining its strength and integrity over time.

Estimates Elastic Properties & Strength

UPV results can be correlated with dynamic modulus of elasticity and compressive strength, giving valuable insights into material behavior and load-carrying capacity.

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.Since CO₂ transport depends on moisture movement, water permeability testing is an effective method to gauge the concrete’s carbonation resistance.
