Geo Penetrating Radar (GPR)
Why Choose Georadar?
Georadar is a geophysical, non-invasive technology** that uses electromagnetic (EM) waves to detect subsurface features with precision and efficiency.
- EM Wave Range: Operates within a frequency spectrum of 10 MHz to 2 GHz.
- Frequency Adaptability:
- Low frequencies (10–80 MHz) penetrate deeper layers, reaching depths of 15–120 meters.
- High frequencies (100–600 MHz) focus on shallower depths of 4–15 meters, providing detailed imaging.
Applications of Low-Frequency Georadar (10–80 MHz):
- Geological Studies: Stratigraphy, slip planes, ancient riverbeds, and zones with high water content or weakness.
- Geotechnical Engineering: Assessing soil properties, identifying seepage, and detecting leaks in dams.
Applications of High-Frequency Georadar (100–600 MHz):
- Infrastructure and Utilities: Locating underground cables and pipes.
- Structural Analysis: Detecting cracks in concrete, locating reinforcing iron within concrete, and analyzing foundations.
Georadar is a versatile tool, ideal for projects requiring accuracy, minimal disruption, and adaptability to various subsurface conditions.
