Non-Destructive Subsurface Investigation & Utility Detection
At Geopin Consult, we specialize in high-precision Ground Penetrating Radar (GPR) surveys for non-destructive subsurface investigation and utility detection. Our advanced GPR systems use electromagnetic radio waves to detect and map subsurface structures, utilities, voids, and geological features without excavation or drilling.
Our GPR surveying services provide critical subsurface intelligence for construction planning, infrastructure development, archaeological investigations, and environmental assessments. With multiple frequency antennas ranging from 100 MHz to 2.6 GHz, we can penetrate depths from a few centimeters to over 30 meters, depending on soil conditions and survey requirements.
We follow a systematic approach to ensure every GPR survey delivers accurate, reliable subsurface data:
1. Site Assessment & Survey Planning: We begin by assessing site conditions, reviewing historical records, and planning the GPR survey methodology. Our team determines optimal antenna frequencies, line spacing, and data collection parameters based on project objectives.
2. Grid Establishment & Control: We establish precise survey grids and control points using GPS/GNSS technology to ensure accurate positioning and alignment of all GPR data across the project area.
3. Field Data Collection: Our certified GPR technicians conduct systematic surveys using advanced GPR systems with multiple antenna frequencies. We collect comprehensive subsurface data along predetermined grid lines or specific areas of interest.
4. Data Processing & Interpretation: We process raw GPR data using specialized software to create 2D radargrams, 3D volumetric data, time-slices, and depth-mapped interpretations. Our geophysicists analyze the data to identify subsurface features and anomalies.
5. Report Preparation & Deliverables: We prepare comprehensive GPR survey reports with annotated radargrams, 3D visualizations, depth maps, and GIS-compatible data. Our deliverables include recommendations for further investigation or mitigation if required.
We operate advanced GPR systems with multiple antenna frequencies (100 MHz - 2.6 GHz) for varying penetration depths and resolution requirements.
Our GPR systems support 3D data collection with high-density grid surveys for comprehensive subsurface visualization and analysis.
All GPR data is integrated with GPS positioning for accurate georeferencing and seamless integration with other survey data.
Our GPR technicians are certified and experienced in data interpretation, ensuring accurate identification of subsurface features.
