GEC Ground Penetrating Radar (GPR)

GPR is an excellent and cost-effective took for locating subsurface objects that are not easily detectable by conventional means such as drilling or soundings. GPR can be used to detect both natural and man-made subsurface features

WHAT IS GPR?

GPR is one of the latest technological advances in geophysical exploration. A GPR system provides a real-time graphic record of a subsurface features without disturbing the material being explored. Exploration depths vary depending upon soil and groundwater conditions.

HOW IT WORKS:

As the GPR radar antenna is pulled along the ground surface, radar pulses are reflected back to the antenna from subsurface interfaces possessing different electrical properties, such as clay, sand, utilities or buried debris. A 2-D subsurface profile, or “linescan”, is developed as the reflected waveforms are displayed on the monitor. Post-processing of data can allow user to view surveyed area(s) in 3-D.

Structural Applications:

GPR is a cost-effective, non-destructive tool for locating embedded steel reinforcement, conduits and voids within concrete structures such as concrete floor slabs, walls and columns.

Ground Penetrating Radar (GPR) is a
non-destructive testing device utilized for surveying concrete floors/slabs, walls, decks, balconies, etc. GPR is a safe, time-efficient system that can provide 2-dimensional real-time results. Post processing of data enables 3-dimensional modeling of the surveyed area(s).

GPR ADVANTAGES OVER X-RAY METHOD…

GPR

X--RAY

  • Real-Time 2-D Resullts in the Field
  • Safe and Tiime-Effiicient Execution
  • Requires Access to Onlly One Side of the Survey Medium
  • X-Ray Requires Development Time
  • X-Ray Method Requires a Safety Zone During Usage
  • X-Ray Requires Access to BOTH Sides of Survey Medium
Comparable Costs
