What is GPR and how to detect interference in engineering works?
In this context, a frequent situation encountered in engineering works is the stage before excavations. It is often necessary for the soil to be studied beforehand to understand the existing underground infrastructure. For this, GPR (Ground Penetration Radar), also known as georadar, is applied in the mapping of interferences on the ground.
According to the ABNT NBR 15.935 of May 2011 standard, GPR is the first choice for the detection of buried infrastructures involving metallic and non-metallic objects. Its advantage lies in the knowledge of underground interference in a non-destructive way (NDM), prior to excavation or drilling, using electromagnetic waves that identify, with high resolution, buried structures and obstacles.
