GPR vs. X-Ray |
- GPR can be used to visualize numerous materials, voids, and leaks at slab grade that X-Ray simply cannot do.
- Inexpensive when compared to X-Ray
- No Gamma Radiation
- GPR can find materials that are ferrous, metallic, or non-metallic.
- No time wasted on film processing
- Accuracy of ¼”
- 3 - 5 Times faster than X-Ray
- Markings only needed on top of slab
- Continuous Digital Images– Infinite Area Size - Printouts Available
|
- X-Ray requires the 2 floors of an area to be shut down due to the presence of radioactive materials.
- More expensive than GPR
- Gamma Radiation present
- X-Ray can only find ferrous metals in concrete.
- Lengthy film processing time
- Accuracy of 1”-3”
- Maximum of 10 locations per day
- Requires markings above and below slab – Time Consuming & Inaccurate
- Viewable area limited by 18” x 18” Film size
