Most concrete scanning companies use ground penetrating radar (GPR) equipment for concrete scanning.
This type of equipment utilises radio waves that are completely safe as opposed to gamma rays that are used in concrete x-ray equipment.
The reason why radio waves are preferred is primarily because concrete x-ray equipment produces radiation.
This radiation can be harmful to humans and requires complete evacuation of the premises during the x-ray process.
GPR technology, over time, has also proven that it can reduce the costs and time involved in the scanning process.
One of the primary reasons is that the results from the scanning are available immediately in real-time.
There is no question that cutting or drilling through a concrete ceiling, floor, or wall can be extremely costly and sometimes dangerous.
This is because the technician does not know exactly what is beneath the surface.
The better concrete scanning companies have qualified GPR technicians that can quickly and accurately find conduits, locate rebar, and identify post-tension cables.
More importantly, he will be able to do this prior to causing any major damage.
This type of equipment can also locate voids and sinkholes in concrete that is below the ground surface. It will also measure concrete thickness.
GPR scanning companies will be able to provide you with detailed information when comparing GPR technology and concrete x-ray technology.
Some construction companies claim that even when they hire a GPR investigation firm, they still hit conduits or other items when cutting or coring.
This occurs even though the technician told them that they would be clear of all anomalies.
However, these issues can occur because the scanning process was carried out incorrectly or an inexperienced GPR technician was used.
To cut corners, some concrete scanning companies employ operators that only do a simple line scan every 4 – 6 inches.
Instead of doing a high-resolution 3-D grid, they try to connect the dots between these wide line scans.
A basic line scan process can sometimes work when trying to locate rebar but post-tension cables and conduits can be easily missed.
It may take a little bit longer to collect all of the data but scanning every 2 inches with a 3-D grid process will, in the long run, save costly damage to post-tension cables and conduits.
It can even prevent a person who is cutting or coring from physical harm.
The primary goal for any GPR technician is to provide accurate details for the client.
Reputable concrete scanning companies know the importance of doing it right the first time.
They only use experienced technicians who understand the various challenges that are involved in proper concrete scanning.
In addition to marking and scanning concrete in order to locate hidden objects in the concrete, it is also important to choose a company that can provide detailed mapped reports.
Detailed mapped reports will include diagrams of all the scanned areas along with depths and locations of every anomaly.
Everything will be plotted to scale and can be used for future work or pre-engineering.
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.
