Ground Penetrating Radar and its use

Within the scope of the geoenvironmental assessment carried out at a facility owned by ANA Airports – GOC (Fuel Operational Group), ETP needed to carry out a preliminary survey of the underground. It was important to ensure that the locations designated for drilling were suitable, with no buried infrastructure that could be damaged or cause accidents. Thus, ETP opted for the use of ground-penetrating radar to achieve the defined objectives.

Taking into account the characteristics of the surroundings, a survey was carried out. The aim was to detect the presence of buried linear structures, commonly known as pipelines (sewage, telecommunications, electricity networks, etc.). In this way, the best location for the installation of two new piezometers for the monitoring network was selected.

A application of this technique allowed not only to identify the piping shown in the client-provided plans, but also enabled the detection and correction of the exact location of one of these linear structures. In summary, its location was validated.

This time, the use of ground-penetrating radar minimized the risks of intersecting pipelines at the site during the direct investigation work for the installation of piezometers.
