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
