GPR
Ground Penetrating Radar
Ground Penetrating Radar (GPR) is a non-invasive geophysical method that utilizes radar pulses to image the subsurface. GPR is typically effective to depths of about 10 meters, but can reach greater depths in highly resistive materials like salt or ice.
- Archaeology:
- Site Surveying: GPR is used to locate and map archaeological features without excavation, allowing for the identification of potential dig sites.
- Preservation: By providing subsurface information, GPR helps preserve the integrity of archaeological sites while gathering essential data.
- Utility Locating:
- GPR is effective for locating buried utilities such as pipes and cables, including non-conductive materials that traditional electromagnetic induction tools cannot detect.
- Construction and Engineering:
- Used for assessing the structural integrity of buildings and infrastructure by detecting voids, cracks, and mapping rebar within concrete.
- Environmental Studies:
- Helps locate buried hazardous materials, such as oil tanks or drums, and assess contamination spread in landfill sites.
- Forensics:
- Employed to locate buried evidence in criminal investigations, including unmarked graves.
