USE GPR TO IMAGE CONCRETE, ASPHALT, MASONRY AND WOOD

Scantech is an experienced provider of high-resolution high-frequency GPR surveys to evaluate concrete, asphalt, masonry and wood structures. We also provide GPR surveys for road, tunnel and bridge deck evaluations.
 

As qualified geophysicists we can guarantee a high-quality GPR imaging service for:

  • Voids
  • Reinforcement
  • Embedded utilities
  • Layer thickness
  • Deterioration

Safety check / Pre-drill Survey

  • Locate targets within concrete structures - electrical conduits, cables, water pipes and all types of structural reinforcement
  • Mark out targets in real-time and/or provide 2D/3D CAD drawing

Quality control / Condition Survey

  • Verify presence, depth and spacing of rebars, pre- and post-tension cables and conduits
  • Measure concrete thickness and concrete cover.
  • Detect voids in concrete
  • Map zones of deterioration

Advantages of GPR for concrete non-destructive testing

  • Only single-sided access is needed
  • Safe and non-disruptive
  • Cost effective: fast imaging of large areas
  • Accurate, high-resolution real-time mapping
  • Locate embedded targets: metallic and non-metallic
