Non-Destructive Measurement of Crack Penetration and Structural Integrity

Crack Depth Test is a critical non-destructive evaluation (NDT) used to measure the depth and severity of surface cracks in concrete structures. Unlike visual inspection, this test provides quantitative data on how deep a crack has penetrated — helping engineers assess whether it is superficial, structural, or indicative of deeper distress. At Global Lab, the Crack Depth Test is performed using ultrasonic pulse techniques (UPV method) or semi-automated probes, ensuring accurate detection of subsurface crack propagation without damaging the concrete.

Why Crack Depth TestMatters.

Evaluates Structural Safety

Determines whether surface cracks are only cosmetic or extend deep enough to affect structural strength and serviceability.

Identifies Active vs. Passive Cracks

Repeated testing over time helps distinguish between static cracks and those that are still propagating — critical for maintenance and monitoring.

Guides Repair and Rehabilitation Decisions

Accurate crack depth data ensures that repairs are designed appropriately, preventing over- or under-treatment.

Monitors Deterioration in Harsh Environments

Useful for assessing cracks caused by thermal stress, shrinkage, corrosion, or seismic activity, especially in coastal or industrial exposure zones.
