Assessing concrete quality and durability.


Nondestructive testing (NDT) for concrete structures is a group of analysis techniques used in the science of materials evaluation without causing damage. NDT allows for the inspection and assessment of concrete’s internal condition, including the detection of cracks, voids, and other anomalies, as well as the evaluation of structural integrity and material properties.

NDT is crucial for concrete structures to ensure their safety, durability, and reliability without compromising their integrity. It helps in early detection of potential issues, assessment of structural health, and determination of repair needs, thereby extending the lifespan of structures and saving costs on extensive repairs or replacements.

  • Shearwave Tomography: Utilizes shear waves to create a cross-sectional image of the interior of concrete structures, identifying flaws and heterogeneities.
  • Impact Echo: Employs stress waves generated by mechanical impacts to detect flaws, measure thickness, and evaluate the integrity of concrete elements.
  • Ground Penetrating Radar (GPR): Uses radar pulses to image the interior of concrete, locating rebar, conduits, and assess concrete condition.
  • Ultrasound Pulse Velocity: Measures the speed of an ultrasonic pulse through concrete to evaluate its quality and uniformity.
  • Schmidt Hammer: A rebound hammer test that provides a quick indication of concrete compressive strength.

Our team of certified NDT technicians & professionals is equipped with state-of-the-art NDT equipment and follows stringent industry best practices. We combine our technical expertise with a thorough understanding of concrete behavior to interpret NDT data accurately, ensuring reliable and actionable insights for our clients.

While NDT is highly effective in identifying a wide range of defects and assessing concrete quality, the detectability of certain flaws may depend on the method used and the specific conditions of the structure. Our Non Destructive Testing experts can advise on the most suitable NDT methods for your specific needs to ensure comprehensive assessment.

If NDT reveals defects or areas of concern, Prime Test Engineering will provide detailed findings along with professional recommendations for the next steps. This may include closer inspection, monitoring, or repair strategies tailored to address the identified issues and ensure the structure’s safety and longevity.
