Working with concrete is a difficult and sometimes time-consuming job.
If you do not have detailed plans of a structure you may be unsure whether there is rebar present, where the utilities are, and where it is safe to cut the concrete.
Even if you do have plans, it pays to confirm that the layout is exactly the same as the plans specify.
Rebar is the term used to describe steel bars or mesh that is used to reinforce concrete, helping it to remain strong and hold tension.
Rebar is very important for larger pieces of concrete since concrete without rebar is weak and can shift or crack.
If you are planning to tear up a piece of concrete, you should confirm where the rebar is.
If not, the equipment that you use to break down the concrete could be damaged when it comes into contact with the rebar.
This makes it quicker to work around the rebar, and you are less likely to damage the concrete.
There are a number of options for finding metal objects in concrete, but perhaps the most commonly used and the most effective is Ground Penetrating Radar.
The appeal of Ground Penetrating Radar is that it is safe and non-destructive.
It sends signals into the concrete, which are then processed through a computer, to determine where there are objects of various densities hidden in the concrete.
Ground penetrating radar can detect rebar, mesh, voids, tubing and post tension cables as well as other substances that are hidden in the concrete, and plots 2D or 3D maps to show you where these things are.
It is safe to use even with thick concrete, and unlike X-ray methods, it does not expose the users to any radiation.
GPR is based on electromagnetic radiation, which is different from x-ray radiation.
It can be used to record reflected signals and to highlight objects (or the lack of objects) in a given location.
This is important for safety and quality control, since the radar may detect cracks which could be a threat to the safety of the building.
Interpreting GPR results is a skill and it can be quite difficult for an inexperienced person to do it.
With proper training, the accuracy of results for detecting even fairly small things such as cables is quite high – between 97.7% and 99.2%, if the latest computerised hyperbola fitting techniques are used.
For this reason, we recommend that those who are considering using concrete scanning equipment enlist the help of the experts.
A scan is only as useful as the knowledge that is gleaned from it, and if you are simply provided with a pretty picture and little guidance on how to read it, then you would almost be better off with no scan at all.
We are a team of experts in modern imaging techniques, and we can help you with concrete scanning, utility location services, concrete imaging, and more.
If you need to dig in an area and are worried about hitting sewer pipes, cables or other utilities, then you should have a full scan of the area done before you start work.
The scans can be done quickly and non-invasively and could save you a lot of time and money in the long run.
Making a mistake could damage your equipment or, worse, leave you on the hook for costly repairs to utilities or services.
A little extra research and preparation will go a long way.
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.
