Non-Destructive Testing: Ground Penetrating Radar

Non-Destructive Testing (NDT) refers to a wide group of techniques used in science and industry to determine properties of materials without significantly damaging the material. Most NDT methods are based on sound or electromagnetic radiation principles. We typically use NDT to determine the as-built construction of structural and non-structural concrete and masonry. Our Primary NDT Techniques Include The Following:

  1. Ground Penetrating Radar (GPR)
  2. Half-Cell Potential Testing
  3. Impact Echo
  4. Rebar Corrosion Testing
  5. Ultrasonic Pulse Velocity

Our techniques are used to measure the following:

  • Location, size, and quantity of pre-stressed, post-tensioned, and conventional reinforcing steel embedded within concrete
  • Concrete cover associated with steel reinforcing
  • Corrosion of reinforcing steel
  • Member thickness
  • Concrete strength
  • Density
  • Discontinuities with concrete such as honey combing and cracking
