Ground Probing Radar (GPR) is a high resolution, field-portable geophysical method that produces graphic sections of subsurface structure. Site investigation applications include the accurate location of voids and buried obstructions, mapping of subsurface soil and rock interfaces and buried archaeological structures; identifying ancient landfill, and detection of buried hazardous waste. GPR surveys are non-destructive, revealing detailed information on subsurface ground conditions without drilling or excavation.
1. Investigates thickness and internal structure of floors and walls.
2. Locates internal steelwork in concrete such as rebar, girders & cable ducts.
3. Identifies ties between courses of brickwork.
4. Locates voids, cracks and delaminations in all types of materials.
5. Finds zones of water penetration and corrosion within defective concrete.
6. Determines thickness of brickwork and masonry construction layers.
7. Locates buried voids & cavities.
8. Determines depth of bedrock and overburden thickness.
9. Finds buried underground storage tanks (USTs) and drums.
10. Tracks non-metallic culverts and sewers.
11. Maps buried foundations and other obstructions.
12. Defines extent of ancient landfills.
