How to Choose The Best Ground Penetrating Radar Services

By Phyllis Stout


Ground penetrating radar services are versatile enough to be used for a number of applications, which range from discovering concealed utility pipes along with conduits in concrete slabs to locating archaeological treasures around excavation sites. This technology basically draws a picture of what's buried underground by transmitting pulses of radio waves straight into the target area. Whenever the waves encounter a blockage, they produce echoes which can be graphically shown on the GPR unit's screen.

There tend to be three basic types of data which can be supplied by a ground penetrating radar device. The standard is actually 2D data, which is the raw data which is made by the GPR and shows up as a series of roughly-drawn lines upon the screen. 3D data is made by merging several 2D readings to develop a 3D picture. Lastly, point data is actually created when the GPR is combined with a global positioning system unit. The coordinates generated from the GPS tend to be mixed with the GPR data to produce as-built drawings upon CAD or perhaps GIS software.

Ground penetrating radar services normally take about three approaches to a GPR survey. The first is to simply examine the site for clues to the desired targets, as well as then make use of this as a starting point for a far more detailed search. The GPR is moved across the suspect region until finally the target is located, and then marked upon the ground or its coordinates logged making use of a GPS. With a mark out approach, an even more systematic search is actually undertaken by dividing the search region into a grid and then moving the GPR throughout every individual square within an organised search pattern. Finally, there is actually the generation of a 3D map of the search region, which can be produced using the data generated from earlier searches while using the first couple of approaches.

When using the services of ground penetrating radar services there tend to be three main considerations to keep in mind:

1. What kind of technology are they using? You may wish to make use of a service which uses the most up to date GPR devices accessible to make sure you get the outcomes you will need.

2. Do they have a highly trained staff? While it is easy to operate the GPR unit itself, you still want to have a professional technician available to interpret the readings to ensure that absolutely nothing is missed.

3. Precisely how long have they already been operating? You will desire to retain the services of a service that's well-established in your area to make sure that they are reliable and will provide you with the services that you might want.
