3 Different Ways for Concrete Imaging and Scanning

3 Different Ways for Concrete Imaging and Scanning

If you’re wondering about the safety of drilling into concrete slabs and other structures, what you need to get peace of mind is concrete scanning and imaging. This is a series of non-destructive tests (NDT) for detecting and measuring flaws or imperfections beneath concrete surfaces.

In the past few decades, numerous imaging and scanning technologies have emerged. Before hiring professionals for surface and concrete scanning solutions, you should first gain a deep understanding of those technologies, and the reason why concrete imaging and scanning are important.

Why is Concrete Scanning Important?

There is always the chance of damaging vital infrastructure while cutting, coring, drilling, or sawing existing concrete slabs. This includes embedded materials like communications and electrical conduits, post tension cables, reinforcing steel, void defections, and refrigerant and plumbing piping.

Skipping out on the scanning process could mean project delays, additional costs, and injuries on the job site. Project managers certainly don’t need any added stress, so scanning and imaging services are always a must before starting a construction project.

3 Methods of Concrete Scanning and Imaging

Now that you know how important scanning and utility locating services are, it’s time to dive in on the various methods and scanning equipment.

1. Ground Penetrating Radar

To scan concrete without causing any damage, ground penetrating radar (GPR) is commonly utilized.  To detect subsurface objects, the GPR sends out electromagnetic pulses or radar pulses with a very particular core frequency.

The antenna then picks up the waves that have been reflected from underground layers, revealing the buried objects.

Choose Ground Penetrating Radar if you need to:

  • Find a safe place to drill, cut, or demolish
  • Locate objects such as post tension cables, rebar, reinforcing steel, and metallic or non-metallic conduits
  • Measure concrete cover and thickness
  • Determine the concrete’s internal condition
  • Uncover defects or voids in concrete

2. Ultrasonic Tomography

This acoustic method efficiently identifies defects in concrete no matter how complex the concrete slab is. This also helps when assessing the thickness and overall strength of concrete structures. It does it through transmitters that send pulses into test objects.

Any reflected signals indicate the presence of defects or interfaces. Using a receiving transducer, technicians can keep a close eye on emitted impulses and reflected waves.

Choose Ultrasonic Tomography if you need to:

  • Precisely measure the thickness of concrete up to 3 feet
  • Detect any cracks or delamination between the Portland Cement Concrete (PCC) layers
  • Locate steel reinforcement
  • Determine deterioration, dowel position, and spalling at PCC joints
  • Learn about material properties like the diagnostics of PCC strengths and asphalt compaction levels

3. Radiography Via X-Ray

X-ray scanning may appear to be outdated technology. Nonetheless, it is dependable in terms of providing a clear picture of what lies beneath. Because X-rays provide less room for interpretation of results—including the status of rebars, corrosion zones, and other faults—they are sometimes even considered more precise compared to GPR.

Unfortunately, this can also emit harmful radiation, and the process is slower overall, with images having to be produced off-site.

Choose Radiography Via X-Ray if you need to:

  • Identify where rebars are situated.
  • Evaluate bar diameter and depth below the surface
  • Search for cracks, foreign materials, and voids
  • Locate variations in density or the presence or absence of grouting in post-tension construction
  • Check welds on pipelines
  • Inspect steelwork production
  • Determine the level of internal and external corrosion

What is Concrete Scanning and What Can It Find?

What is Concrete Scanning and What Can It Find?

Before a renovation or construction project begins, concrete scanning is essential. This is the process of evaluating concrete slabs or columns before core drilling. Typically, technology like Ground Penetrating Radar (GPR) is used to spot buried and embedded objects. However, this method is ideal because it’s completely safe and nondestructive.

If you think that you need surface and concrete scanning solutions, it’s best to learn about the ins and outs of the process first. Let’s start with what exactly happens during a typical inspection of a concrete slab.

What Happens During Concrete Scanning?

During a concrete scan, a professional will deliver high-frequency electromagnetic waves using GPR technology through your concrete floor or wall.

Another specialist will then come in to interpret the data provided by the scanner. From there, they’ll be able to show you what’s hidden underneath your concrete and where it is exactly.

Types of Concrete Structures that Need to be Scanned

Any concrete surface can and should be scanned before any cutting or drilling is done. Some samples of structures that need to be scanned are provided below.

  • Slab on grade
  • Roadways
  • Bridges
  • Beams
  • Decks
  • Pylons
  • Walls
  • Balconies
  • Encasements
  • Tunnels
  • Sidewalks
  • Columns
  • Floors
  • Ceilings

Common Objects Found During Concrete Scanning

A proper concrete scan can uncover a large variety of objects in your chosen area. Below are just a few examples:

  • Metal rebars and other reinforcing steel members
  • Post-tension cables
  • Electrical conduits
  • Piping
  • Plastic tubing
  • Water lines

The Importance of Concrete Inspection

Before you do any work on your concrete like drilling, cutting, or repairing, you must first determine where utilities and reinforcements are located. This will save you time since you won’t have to spend hours looking for a secure area where you can start working on.

Investing in concrete scanning can also guarantee that you’ll be able to cut and drill safely without harming your tools or the materials that are hidden underneath the concrete.

Additionally, the process can help ensure and maintain the structural integrity of a structure’s foundation.

Check out even more benefits of concrete scanning services:

  • Reduces the possibility of damage to utilities, rebar, post-tension cables, pipes, and conduits
  • Lowers the risk of personal injury
  • Prevents costly mid-project repairs
  • Simplifies drilling, cutting, and coring

How Much Does Concrete Scanning Cost?

Important factors to consider when determining the price of a concrete scan are the location, area size, and the complexity of embedded materials. That said, the cost varies widely from case to case.

Don’t let this discourage you though. Just think of the construction delays, additional costs, and other possible headaches that can be put to rest with a carefully planned and scheduled concrete scan.
