Prior to ground penetrating radar, x-ray was the only means of "looking" through concrete to identify embedded items such as rebar, conduit and post-tension cables. Concrete x-rays poses a serious health risk and is not as fast, accurate or as efficient as GPR. Structural Radar Imaging specializes in GPR.
Ground Penetrating Radar and x-ray are both used to find conduits, locate post-tension cables, locate pipes, locate buried lines and finding unknown items in concrete slabs among other uses. A few advantages of using GPR over radiography in Washington, Oregon, Alaska and Hawaii are:
- No need for evacuation, GPR is safe.
- There is no radiation involved, so there are no health hazards
- No chance of accidental exposure to gamma radiation
- Real time results!
- Access from one side is all that is needed allowing us to scan slab on grade.
- GPR is cheaper than concrete x-ray technology
- GPR uses radio waves no more powerful or harmful than those picked up by household radios
- GPR can provide information about the depths of features in the concrete, x-ray cannot.
- GPR is quick and portable
- Ground penetrating radar is non-destructive and non-invasive
- Surface penetrating radar has 3D imaging capabilities
- Ground penetrating radar gives improved accuracy
- GPR images through floor coverings
Concrete x-ray is an inefficient method for seeing through slabs. Concrete x-ray is also unable to look into the ground because a film must be placed on the opposite side of the slab as the source. Concrete x-ray is only able to look at supported slabs, or structures where both sides are accessible.
GPR is an invaluable tool to use when safe concrete testing is needed.
