Our 3D GPR systems enable large-scale mapping with:

  • Extremely short acquisition times.

  • Decades of experience in applied geophysics.

  • Output seamlessly integrated into BIM systems.


Applied geophysics

Geophysics is a branch of natural science that explores Earth’s processes through physics methods. Geophysical techniques provide insights into characteristics that cannot be directly measured, necessitating indirect information.

Typically, stress situations are induced, and the response of the media is studied using electromagnetic, optical, or mechanical methods. With decades of experience, coupled with high-profile scientific and academic collaborations, GRS offers comprehensive services and advice on various geophysical surveys, ensuring the most effective and efficient methodologies for clients

Accurately identifying the position of piping or underground utilities is critical at every stage of the construction process. This information aids project engineers in evaluating alternatives, supports companies in preventing accidents during construction, and provides project managers with insights into asset maintenance. GRS stands as a leader in this field, offering services conducted by technicians with decades of experience and utilizing the latest generation multi-array GPR equipment. This ensures productivity levels and volumes that set us apart from other companies.

Verification of engineering structures is crucial for effective routine maintenance planning. Leveraging extensive experience, GRS provides detailed information on the presence and position of iron elements, even in multiple layers, as well as information on cement thickness and the presence of voids. These surveys are widely applicable in various engineering structures, including tunnels, viaducts, and buildings.”

The GPR (Ground Penetrating Radar) methodology stands out as one of the most flexible and effective tools in applied geophysics. In recent years, GPR has gained increasing recognition as an excellent non-invasive and non-destructive technique for characterizing structures built with materials like reinforced concrete or brickwork for engineering purposes. With certified technicians and state-of-the-art high-frequency GPR instruments, our company efficiently conducts thorough structural surveys.

Verification trenching, while detailed, is often economically and time-wise burdensome during surveys for archaeological elements in unpopulated areas, and results may not always meet expectations. Utilizing 3D GPR alongside other geophysical methodologies allows us to comprehensively explore large areas, identify points of interest, and plan subsequent excavations more effectively.
