Ground penetrating radar’s versatility coupled with integration with mapping and GPS technology, calibration techniques and 3D capabilities of a sophisticated subsurface imaging system allows it to be adjusted to suit a variety of applications.
Ground Penetrating Radar (GPR) is a geophysical non-destructive technique (NDT).
The basic principle of GPR is the transmission of a short electromagnetic pulse, with a specified frequency, down into the ground and the recording of reflected energy as a function of time, amplitude and phase. The specified central frequency is controlled by the transmitter and receiver antenna length. The reflected energy is recorded as a “pattern” on radargrams which are displayed in real-time. The radargrams are displayed in real-time on the control unit and basic interpretation can be conducted on site.
With new build construction and renovation projects, the likelihood of needing to cut or core a concrete slab is high. There is an inherent risk of striking rebar, electrical and communications conduits, and post-tension cables during the cutting, coring, or drilling process. The cost of such mistakes can be prohibitive. Unreasonable constraints on already thin budgets can occur, as well as infusing havoc into your schedule and creating a safety hazard for your employees. Our well-trained, skilled, experienced technicians respond quickly to service requests, especially when your need for concrete scanning is a last-minute discovery. The result is professional, accurate and timely scanning – the exact satisfaction you’re seeking to mitigate risk and keep your employees safe.

To ensure the overall timely success of the job, utility detection is critical to any construction project where subsurface excavation is planned. If ignored, budget overruns multiply, your schedule turns chaotic and there’s risk of injuries taking place on your job site. To achieve the complete success you’re looking for, you’ll want to connect with an expert service provider like ORSCO (Pty) Ltd.

We offer our clients a comprehensive range of reporting options, from marks on the ground, to a basic field sketch, to a 3D/4D, GIS Auto CAD report that pinpoints buried electrical, water, gas, communication, sewer and storm drain lines.
A geographic information system (GIS) is a framework for gathering, managing, and analysing data. Rooted in the science of geography, GIS integrates many types of data. It analyses spatial location and organizes layers of information into visualizations using maps and 3D scenes. With this unique capability, GIS reveals deeper insights into data, such as patterns, relationships, and situations—helping users make smarter decisions.
Our software makes complex GPR analysis easy with intuitive tools to organize, edit, process and plot your GPR data. Powerful visualization, analysis and integration tools allow you to produce impressive reports quickly and easily, including overlaying GPR data and interpretation into Google Earth.
The most advanced subsurface mapping solutions currently available in the market allow for a complete digital workflow (from data acquisition to final deliverables) in the field. However, sometimes time in the field is limited by site or weather conditions, or the data needs a deeper analysis (soil conditions, positioning errors or project specific requirements). Advanced GPR data analysis gives the deepest insights possible into your data.
The Proceq Gs8000 subsurface mapping system uses a Stepped Frequency Continuous Wave technology (SFCW) which gives the GS8000 an ultra-wide bandwidth, with both low and high frequencies, to achieve the perfect mix of penetration depth and resolution, even under challenging ground conditions. The Proceq GPR Subsurface iPad app enables 3D visualization on site and enables the utilities to be projected onto Google Earth since the true geo-location is obtained with the integrated GNSS receiver, Ma8000. e localization of metallic and non-metallic objects of small or large dimensions.
The VIY5-300 Ground Penetrating Radar (GPR) among the most effective solutions to perform GPR surveys in a short time and at low cost thanks to the acquisition and analysis software Synchro GPR and Planner 3D. The VIY5 system allows the acquisition of data useful for the investigation and processing from a PC. The software also allows you to set the data any time, keeping the original data unaltered. The wide range of antennas responds optimally to the different needs of the professional and to the characteristics of the terrain being inspected, even in the case of in-depth investigations or where it is required. a more accurate analysis of the subsoil and th
The LMX200™ builds on the capabilities of the LMX100™. The LMX200™ provides unprecedented insights and target confidence to detect traditionally non-locatable subsurface features such as: Non-metallic pipes, Underground Electrical Cable, Concrete storm/sewer systems, Utilities where installed tracer wiring has failed, Underground storage tanks, Drainage tiles, Septic system components, Non-utility structures such as vaults, foundation walls and concrete pads.
Our Ground Penetrating Radar solutions empower informed decision-making. Understanding what lies beneath the surface in materials like soil, rock, rubble, pavement, concrete, water, ice and snow opens endless possibilities.
