Is Digital Concrete Rebar Scanning Better Than
GPR in Bay Area?

• In a construction job, there are a variety of
  ways for scanning concrete structures. Each
  method comes with its own share of merits as well
  as demerits. One method which works absolutely
  fine in one construction environment may fall
  back in a different setting. This article
  compares two widely used digital concrete rebar
  scanning techniques GPR and concrete X-ray, so
  that you can pick the better one as per your
  construction needs.

Major Differences between GPR And Concrete
X-Ray

• Two most popular scanning methods are GPR and
  X-ray scanning. These are non-invasive digital
  concrete rebar scanning technologies. Lets take
  a look at the differences between both methods to
  better understand which one will suit your
  construction project.

Concrete X-Ray Scanning

• Concrete X-ray scanning method has been used in
  the construction industry for a long time, due to
  its accuracy. There are two ways of using this
  technology
• Digital X-ray scanners digitally scan and render
  an area, by showing the scanned area on an
  electronic device.
• Regular X-ray scanners process your renders from
  film.
• Technical interpretation is required in both
  methods to accurately locate and identify the
  structures within concrete. On the negative side,
  the devices used in this method emit radiations
  which are hazardous for human health. Also, it
  takes a lot of time to scan a site, which can
  increase the overall call of project. This is
  undesirable if you are working on a tight budget.

GPR

• Ground Penetrating Radar (GPR), is a more viable
  option when budget is of high consideration, and
  you are working on a tight budget. It is also
  desirable for speeding up the process of digital
  concrete rebar scanning in Bay area. Moreover,
  when consistent results are required, then GPR is
  ideal scanning option because it can scan large
  areas at deeper subsurface levels.
• On the challenges part, GPR requires more
  professional operators and technically adept
  contractors to interpret and analyze the massive
  amounts of raw data.

When to pick GPR over Concrete X-Ray Scanning?

• As discussed above, both digital concrete rebar
  scanning technologies have their advantages and
  disadvantages. Yet, looking at the bigger picture
  reveals that GPR presents fewer challenges, and
  comes at a fairer price. Below, we have discusses
  why GPR is better than X-ray scanning.

Real-Time Concrete Scans

• While X-ray concrete scanning takes some time to
  display results, GPR provides immediate scan
  results without any additional steps. Also, it is
  non-invasive, therefore, there is little
  work-site footprint. For quick results and
  reports, you can use GPR for spot analysis.

8
Cost-effective concrete scanning option

• GPR helps you do large scans in a short time,
  which allows you to save significant time and
  labor cost. Resultantly you can save more using
  GPR digital concrete rebar scanning, as compared
  with the X-ray concrete scanning procedure. If
  you are working on an underground site, then GPR
  is an ideal option for locating and marking out
  underground facilities.

9
Safety on the Job

• GPR is the safest digital concrete rebar scanning
  in bay area, as it emits lesser amount of
  signals- even less than your smartphone. Also,
  while working with a GPR, there is no need to
  evacuate a site because of the fear of radiation
  exposure to workers. Concrete X-ray scanners
  demand extra precautionary measures.

10
3D Scan Results

• GPR is ideal for digital scanning of concrete
  structures. On the other hand, X-ray concrete
  scanning equipment can only scan one side of a
  structure. GPR can also identify underground
  facilities such as tunnels.

11
Low Noise Emissions

• One major reason for picking GPR over X-ray is
  its ability to operate quietly. GPR allows
  performing of concrete scans any time and any
  day, without interrupting activities on site
  surrounding. So, you dont have to worry about
  disrupting offices or schools nearby due to your
  construction work.

12
Increased Accuracy

• Digital concrete rebar scanning such as GPR is a
  radar-based technology, which can scan a concrete
  slab with a minimum of 4" to an accuracy ranges
  of -/ 0.5". Whereas, such accuracy is not
  possible with X-ray scanning.
