Ground Penetrating Radar

At Retro Geoenergy, we provide advanced Ground Penetrating Radar (GPR) services to deliver high-resolution, near-surface subsurface imaging for a wide range of applications. GPR is a non-destructive geophysical technique that uses high-frequency electromagnetic waves to detect and map buried objects, structures, and stratigraphy.

By transmitting radio waves into the ground and recording reflections from subsurface materials, GPR provides real-time profiles of shallow geology with excellent spatial resolution. This makes it highly effective for engineering, environmental, groundwater, archaeological, and geotechnical investigations.

Geotechnical & Civil Engineering

• Mapping soil layers, depth to bedrock, and structural discontinuities.
• Assessing subsurface conditions for roads, tunnels, bridges, dams, and foundations.
• Locating voids, sinkholes, fractures, and cavities that may affect infrastructure.

Groundwater & Environmental Studies

• Mapping shallow aquifers, water table depth, and subsurface stratigraphy.
• Identifying contaminant plumes and leachate pathways.
• Locating buried waste, tanks, and pipelines for environmental remediation.

Archaeology & Cultural Heritage

• Detecting buried walls, foundations, tombs, and artifacts.
• Non-invasive surveys to preserve archaeological sites.

Utility Detection

• Locating underground utilities, cables, and pipelines with high accuracy.
• Preventing damage during construction and excavation.

Mining & Quarrying

• Mapping overburden thickness, shallow ore bodies, and fractures.
• Supporting blast design and safety assessments.

• High-resolution 2D GPR profiling for shallow subsurface mapping.

• 3D GPR imaging for detailed structural and object detection.

• Multi-frequency antenna systems for variable depth and resolution (typically from 1 m up to 30 m, depending on soil conditions).

• Data Processing & Interpretation:
- Time-zero correction & filtering
- Migration and deconvolution
- Amplitude and attribute analysis
- Depth conversion using velocity models

• Integration with ERT, seismic, and borehole data for robust subsurface characterization.

• High-resolution 2D radargrams (profiles) for interpretation.

• 3D volumetric models of subsurface features.

• Detailed maps of utilities, voids, and geological layers.

• Technical reports with interpretation and engineering recommendations.

• Cutting-edge GPR equipment with multiple frequency antenna options.

• Capability to detect features in complex conditions (clays, sands, urban areas).

• Expertise in multi-disciplinary integration with seismic, resistivity, and geotechnical data.

• Proven track record in engineering, groundwater, mining, and archaeological investigations.
