What is a georadar

A Georadar is a ground penetration radar also called Georadar GPR, used to find objects as well as subsurface anomalies such as caves, underground rivers, subsurface cracks, material changes, contaminated water, drinking water, concrete inspection, wiring detection, pipe, sewerage and much more.

It uses electromagnetic waves that travel at different speeds depending on the type of material they penetrate; the rebounds of electromagnetic waves are processed by the Georadar, resulting in a Radargram where you can see the speed changes of the electromagnetic waves.

How Georadar works.

We process such data, resulting in an interpretation that is presented to the client in a simple way, in order to be used by the personnel in charge of the projects.

This allows us to know for certain what is in the place where the study is carried out, allowing the projects to be developed more safely and saving many costs.

In this drawing we can see how electromagnetic waves are reflected when they find another material with a different Relative Dielectric Permitivity, the waves that continue downwards are attenuated by the conductivity of the Material until it disappears.

The electromagnetic waves that the radar drives are influenced by two parameters: Relative Dielectric Permitivity and Material Conductivity.

For this reason when we carry out georadar studies in different areas of Mexico, it is very important for us to know the geology and hydrogeology of the place and thus be able to do the calculations of Relative Dielectric Permitivity and Conductivity of the Materials that make up the subsoil.

When we raise the data in the Yucatan Peninsula as well as in Cancun, Riviera Maya, Tulum these calculations are completely different from other parts of Mexico where these values change, hence the importance of knowing the geology and hydrogeology of the area.

Examples of Radargrams:

We carry out these studies in different locations with different antennas and in different floors, we process the data with a Software produced in Sweden.

In example A we can see a record of communication lines in brown and an underwater cave in blue.

The material of the soil is limestone.

In example B we can see a cave in brown.

In example C we can see:

*The floor is made of Limestone.

*In the blue line is the water table.

*In brown is a small cavern.
