Utility Scanning and Mapping
3D Underground Utility Survey
A radar profile is built up of scans (traces) collected along a selected line path. Each profile consists of enhanced high-frequency radio imaging which provides subsurface information based on the variations in the Dielectric Constants (The Electrical Conductivity and Resistivity) of materials.
The recorded reflections can be analyzed in terms of shape, travel time and signal amplitude to provide information about a target’s size, depth, and orientation in relation to the material around it.
Benefits of 3D Underground Utility Survey
• 3D output
• Clash detection
• No excavation required
• Eliminate the risk of injuries and increase safety level
• Great time saving
• Cost reduction
• Highly accurate data
• No operation interruptions
• Environmentally friendly operation

GPR Field Operations
The system is to be configured to provide sampling (Scanning) with high resolution to the required depth below ground level (bgl) using the proposed GPR unit with DF antenna (250/700 MHz).
