Ground Penetrating Radar Unearths Subsurface Obstructions

Ground penetrating radar is an example of how cutting-edge technology can simplify the job once

considered a “next to impossible” chore. When it comes to detecting what exactly lies within the surface

of dry sandy soils or massive dry materials like concrete or limestone, Ground Penetrating Radar or GPR

uses high frequency wave pulse in the form of electromagnetic energy that is shot into the subsurface of

the target material. The working principle of this technology is exactly the same as an aerial radar. The

GPR antennae uses a certain frequency, and puts out wave-pulses into the ground or concrete to measure

its depth or inherent subsurface items or obstructions. GPR can locate underground utilities, pipes,

conduit, void, water intrusion, pt tendons, rebar and more. It can even assess concrete.

Why GPR?

Concrete scanning using GPR ensures that the work is done efficiently without rendering any safety

related threats to the professionals. Back to the days of 1980’s, this technology made its headway into

detection of subsurface objects. Professionals relied on it for its efficacy of measuring up the depth of a

concrete slab or to detect the exact condition of buried object.

It is not an exaggeration if we say GPR has changed the definition of locating utilities or gauging the

depth of a buried object. Imagine if the construction engineer declares that the property can’t be used

for building a home because of certain issue related to its subsurface as detected by GPR. Countless

amount of labor-and intensive works involved into digging or drilling the surface would be averted, thus

saving the owner from considerably expense on labor costs and damages.

Instead of blindly drilling or coring to find out that your contractor cut through a conduit or utility line,,

ground penetrating radar makes the job much simpler for professionals. Utilizing GPR will avoid

unnecessary risks and expensive delays.

The main purpose of GPR is to help the client to be informed of subsurface items that are not detectable

by visual means. In addition, GPR can assess the quality of a concrete slab (frail or sturdy) to get an idea

whether the subsurface ground may possibly collapse under a load, such as in the condition when it has

cracks, voids or deteriorated rebar.

GPR uses high frequency or typically polarised electromagnetic wave that is harmless and a non-

destructive way to avoid possible damages and assist in planning. In concrete scanning with ground

penetrating radar, the GPR technology helps trained technicians to locate rebar and post tension

cables or other buried materials in order to ensure safe and efficient drilling, thereby preserving the

integrity of the survey site as well helping the clients to conduct core drilling without mishaps.

Underlying obstructions beneath a concrete slab, if undetected, can pose a risk of potential damage.

With GPR technology, the location and depth of such risks can easily be detected, thus allowing for

safer construction.

GPR is an effective way of finding location and depth of subsurface objects to make sure you

understand if they are risky or safe so that work can proceed safely, without inviting any danger. For
