GPR Applications

Using Ground Penetrating Radar Applications

I like to read things. Let me clarify that, I like to read interesting facts on the internet as a means of expanding my sphere of knowledge. Some people would be curious as to why I do this? What’s the point of reading facts that I would probably never use? My response is: why not? The information is out there, why not lap it up and have the u1knowledge in your hard drive just in case the opportunity arises to utilize it! Last week I landed on a geology site and discovered a particularly interesting article on ground penetrating radars; as well as their applications.

Ground penetrating radar can be likened to radiation seismology. This doesn’t mean much to people who haven’t studied geology or even taken a moment to find out about it, so let me explain.

Ground penetrating radar is a method of determining whether or not objects are buried underneath the surface rock, sand or ice. It should be noted that this ground penetrating radar (GPR) can also detect cracks in the substructure and changes in material.

Ground penetration radar procedures can be applied in various disciplines beyond geology. In this earth science it is used to discover what is lying below the bedrock; however, when used in engineering and environmental disciplines it is used to define contamination in landfills.

u2GPR can also be used on archaeological sites and in cemeteries for mapping purposes; whereas law enforcement will utilize the method in determining where illegal graves and buried evidence may be found. The military will use this method as a means of finding landmines.

In conclusion, ‘surfing’ the internet can be time-consuming; but it can lead to an understanding of different types of applications like the useful ground penetrating radar.

Understanding Ground Penetrating Radar Applications

When I left university I was rather excited about entering the world with my piece of paper. This degree showed I was trained in a specific field and was smart enough to know what I was talking about. At times, when around non-university graduates, I felt quite smug knowing I had something they didn’t. It was only when my boyfriend would come home and talks about his work as a geologist, or rather a geologist’s assistant that I felt insanely ‘dumb’.

While I knew about Freud and Kinney, he knew about seismology and ground penetrating radars. He would sit at the table and explain these procedures to me in simple words, making me gaze in awe and loathing at his coolness. The ground penetrating radar was so intriguing.

S. Price states;  ground penetrating radar (GPR) is, as the name suggests, a means of penetrating the ground with several radars to determine whether or not an object is buried underneath the stone, ice or other structures. It also identifies any alterations in the material, and any cracks or voids.

How? A question I found myself asking numerous times. Simple, he would say. The radar pulses image the subsurface and use high levels of electromagnetic frequencies to be sent into the subsurface. When and if the wave hits a buried object, crack or void then it will bounce back. The range of the electromagnetic pulse is measured on a spectrum and is limited by the conductivity of the ground.

He said that if conductivity is high, the penetration depth is low because the electromagnetic energy disappears into the substructure’s heat causing a loss of signal. If conductivity is low (like in ice), then penetration can be as high as hundreds of feet.

GPR are easy to use, safe and more sophisticated than most methods in geology. I wish I had more access to them in my studies.

The Uses Of Ground Penetrating Radar In The Construction Industry

Ground penetrating radar is a very well established tool because it helps to locate underground and encased objects that could be dangerous or damaging if they were to be uncovered or accidentally destroyed by construction efforts.

GPR is a real-time procedure that can immediately locate such underground items as electrical conduits that are buried in concrete, post tension cables, rebar and other such items that if cut or damaged could prove costly and dangerous.

This is a very useful tool because it provides a non-destructive way to detect elements that are hidden within concrete. It can locate targets that are encased within concrete and pinpoint where they are in a fast and safe manner.

Visit www.ScanConcrete.com.au for more detailed information.

The current technology allows the user to rapidly evaluate a concrete slab in a user friendly and a cost effective way in order to scan an area and find out what is located within. The GPR can scan larger areas of a concrete project in more than one passing motion and then put the images together to form a 3-D image. This gives a very accurate picture of where items are located, so an exact placement can be made.

This type of accuracy saves time and money because it allows safe drilling, cutting and coring of concrete, so no down time is required and no injuries or loss of life is a threat.

Ground penetrating radar is also a real boon in the mining industry, as rocks and hard surfaces can easily be analyzed as far doing a simple scan can discover faults, fractures and joints, so geologists will know the exact structure of what they are dealing with.

When dealing with minerals, an entire vein of the mineral can be tracked so it is known exactly where it goes. The detection of diamonds, gold, silver, and titanium is enhanced with these methods.
