Ground Penetrating Radar (GPR) Surveys

Ground Penetrating Radar (GPR) is a geophysical NDT (non-destructive technique). 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 antennae 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. Often data is recorded and processed and analysed off-site using specialized software.

Utility Locating With Ground Penetrating Radar

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. We offer you a comprehensive range of reporting options, from marks on the ground, to a basic field sketch, to a full-blown report (GIS Auto CAD) that pinpoints buried electrical, water, gas, communication, sewer and storm drain lines. Our report provides you with a permanent utilities location record for future reference.

Concrete Scanning With Ground Penetrating Radar

With new build construction and renovation projects, the likelihood of needing to cut or core a concrete slab is high. There is inherent risk of striking rebar, electrical and communications conduits, and post tension cables during 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.

GPR Reporting

Once the Ground Penetrating Radar (GPR) data collection in the field is complete, the next step is to pull out the key information and images and generate a final report. The EKKO_Project 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 quickly and easily produce impressive reports, including overlaying GPR data and interpretation into the Google Earth.
