Concrete x-ray and industrial applications from ScanMan

Concrete x-ray is the term that is frequently used in the construction industry. Technically it is called Ground Penetrating Radar. At several sites during construction it becomes essential to learn what is contained beneath the surface. Ground Penetrating Radar or GPR is an extremely beneficial technology which helps in detecting anything under the ground. It can x-ray the solid materials precisely without destructing the matter. The Ground Penetrating Radar System is an extremely useful tool for evaluating the concrete structure.

It is easy to determine concrete deterioration with the help of GPRS. It is utilized to map the concrete condition of the old bridge decks. This is achieved by measuring the dielectric properties of the concrete material coupled with the signal attenuation throughout the thickness and reinforcement reflection amplitude. This methodology effectively estimates the cumulative deterioration. On running the concrete x-ray over a pre-determined site a graphic evaluation of the area is displayed.

This technology can be applied for Pavement Evaluation. Determination of the thickness of the asphalt or concrete pavement can be easily obtained. Investigation into surface cracking and finding rebar or other subsurface features within the road can be efficiently achieved with the help of concrete x-ray. It is necessary to know the pavement condition before the expansion of the lane's breadth. The condition can be determined with the help of GPRS or concrete x-rays. At times during construction of certain infrastructure, rebar depth and slab thickness has to be determined. These can be detected and investigated with the assistance of the concrete x-rays. GPR is excellent for concrete inspection since it can determine rebar spacing and bar elevation apart from slab thickness. With the help of concrete x-ray you can clearly see inside the concrete slabs and determine the location of embedded conduits.

The GPR can be used in assessment of railway track substructure. It can detect the presence or absence of layer interface 'fouling' and layer thickness. Trapped water under the ground and buried utilities can be located. By applying the usage of the radio waves to penetrate the substructures, concrete structures and soil, the GPR can locate most abnormalities.

Concrete imaging is yet another application that is done with the help of Ground Penetrating Radar. It allows a complete mapping of the hidden elements on the slab surface.
