Bridge & Bridge Deck Testing

NDT uses sonic/ultrasonic pulse velocity and impact echo measurements in bridge and bridge deck testing to determine the dynamic strength of concrete and identify and map areas of weak, delaminated concrete as well as determine thickness of concrete elements and length of pile foundations. We also use ground penetrating radar (GPR) in bridge and bridge deck testing to determine rebar spacing and depth of cover and locations of cracking and delamination with moisture entrapment. Half-cell measurements are used to determine the potential of rebar corrosion. We use geophysical seismic refraction measurements to determine bedrock depths and soil types at bridge abutments and piers of scour critical bridges. And we use seismic cross-hole measurements in bridge and bridge deck testing to obtain the compressional and shear wave velocity of soil and bedrock for seismic risk analysis.

Our testing data are used to evaluate the integrity and condition of:

  • Bridge Decks
  • Abutments
  • Piers
  • Bridge Arches

We also test for:

  • Determining Pile Footing Lengths
  • Post Tension Duct Voiding
  • Reinforcing Spacing, Depth of Cover, & Size
  • Scour Susceptibility
  • Soil & Bedrock Compressional & Shear Velocity Values for Earthquake Analysis
