Before construction workers start drilling or cutting through concrete, they need to know exactly what’s inside or behind the concrete slab.
Cutting through electrical wiring can cause significant damage to neighbouring areas and also to the construction site itself.
To prevent these mishaps, you have two options: concrete scanning and concrete x-rays.
Although both these methods provide similar results, the technology used is different.
Concrete x-rays, also known as radiography, use a radioactive source to find hidden utility lines underneath concrete structures.
They produce images on film with the machine scanning the surface of the slab to deliver the required results.
The x-ray scanner will scan not only the lower surface of the slab but also the upper surface.
This provides clear images of the area and prevents construction workers from damaging water pipes or electrical cables.
Concrete scanning, on the other hand, uses electromagnetic energy to scan through the concrete slab and return reflected signals.
These signals reveal the underlying lines and pipes below the subsurface.
The high-resolution images along with detailed reports give workers a precise indication of the area that they need to avoid digging.
One of the reasons why concrete scanning has the upper hand over concrete x-rays is it is a safer method because it doesn’t emit radiation.
Concrete scanning emits approximately 1/100th of the radiation level that an average smartphone emits.
So, you can understand why most engineers prefer this method instead of concrete x-rays.
Another significant difference between concrete scanning and concrete x-ray is the time taken to deliver the results.
Concrete scanning takes less time since the operators only need to scan one side of the slab.
Concrete x-rays usually scan both sides of the slab, and this elongates the entire process.
Moreover, concrete x-rays are only useful for smaller areas with shallow depth as they can only scan through concrete slabs with a maximum thickness of 20 inches.
However, concrete scanners are more powerful than x-ray machines.
As well as being able to scan a vast area, they can also scan through concrete that is more than 300 mm thick.
This is another factor that gives concrete scanning the edge over x-rays.
The GPR technology used in the concrete scanning process is cheaper compared to the radiation technique used with the x-ray method.
Moreover, the operators need to take a lot of safety measures to perform concrete x-rays, and that makes the entire process very cumbersome.
Concrete scanners don’t require any significant precautions.
The operator marks the area that needs scanning and sets up the machine quickly to scan the location.
Although the primary objective of both these methods is similar, they have their pros and cons.
However, when you compare the two, concrete scanning is a better alternative than concrete x-rays because of the price, safety, time, and efficiency involved.
Construction engineers often prefer concrete scanning because of the benefits compared go other scanning techniques.
If you have any construction or excavation projects on the go, it is vitally important to hire a concrete scanning company to scan the location first.
