Ground Penetrating Radar (GPR) versus X-Ray

Ground Penetrating Radar (GPR) versus X-RayThe use of GPR in construction, inspection and concrete repair has many advantages over older x-ray methods. Simply put, GPR is safer, more economical, more versatile and more accurate than x-ray.

  • More Economical - GPR gives real-time on-site results so it takes a fraction of the time of x-ray development and processing.
  • Safer - GPR uses an electromagnetic radar pulse that has no harmful effects. X-ray processes requires a potentially dangerous radiation source and requires evacuation of adjacent areas.
  • More Versatile - GPR only requires access to one side of concrete slabs to image them. X-ray requires two-sided access so the x-ray film can be placed on the opposite side for exposure.
  • More Accurate - GPR displays real-time 3-D images at your location with proven accuracy. X-ray film can mistakenly be rotated, flipped or improperly lined up to provide innaccurate target locations.

X-ray requires the evacuation of surrounding areas (which includes floors 50' above and 50' below) due to radiation safety concerns. Just this fact alone makes GPR a superior alternative to x-ray. The time lost because of evacuation can be substantial depending on the size of the project. GPR units are easily portable and can be "in and out" in a fraction of the time and they eliminate the safety concerns of dealing with a radiation source.

When you consider all the factors, GPR is clearly a better solution for the concrete inspection, construction and repair industry than X-ray methods.
