Ground Penetrating Radar
MME’s ground penetrating radar (GPR) services cover a wide
range of nondestructive testing applications. The application
of the technology is often used in conjunction with our other
services, thus bolstering a broader and deeper solutions
package.
GPR has been called the “newest thing in NDT” in
engineering circles, but the technology has been used in the
military for almost 30 years. |

GPR is now widely used in civil
engineering, building construction, archaeology, geology, and
many more applications. MME is proud of it’s GPR services in
the following areas:
|
Concrete
structure evaluation |
We locate reinforcement in elevated
slabs and slab on grade, providing depth of cover and
orientation; detect voids such as empty block cells, and
slab thickness.
|
| Pavements,
driveways, runways |
Using this completely non-destructive
testing technique, we can determine the
thickness (or
variation in thickness) of any slab on grade.
|
| Utility
location and mapping |
Using multiple antenna outfits, our
state of the art equipment is used to locate buried
pipes, cable conduits buried several feet below the
surface. We also quickly and accurately
locate
underground storage tanks and other buried objects.
|
| Road testing,
bridge decks |
The cost of repairing a section of a
roadway that has caved in due to sinkhole formation or
water erosion can be tremendous, while being dangerously
inconveniencing normal public life as well. Our
high-resolution antenna is used in the study of the
deterioration of bridge decks. Detection of sinkholes
and other subsurface anomalies with our GPR system can
help avert the tremendous costs due to damages to life
and property.

In the
evaluation of concrete structures, GPR delivers
solutions that are beyond comparison to that offered by
traditional radiography or with metal detectors. GPR
data processing allows us to generate reports with 3-D
data representation that makes it easy to interpret and
use the results of the evaluations. Multiple layers of
reinforcement in concrete structures can be detected. |

|
Moreover, since RADAR energy does not pose any health risks
to personnel, most jobs can be performed during normal work
hours without the need for special allowances. |
|
Results are obtained quickly – in many cases, instantly – and
GPR is very cost effective.
Evaluation of concrete structures by radiographic methods
costs more and usually requires access to two sides of the
structure. With our GPR system, we only need access to one
side.
Our Ground Penetrating Radar evaluation technique saves
time and money. It gives quick and reliable results. GPR is
the modern way to avoid the high costs of repairs of damaged
reinforcement and buried utility lines.
It is the vision into the make-up of civil structures and
the subsurface that leads to informed decision making in the
field and at the office. |
