Professionals in the construction industry need to be able to cut through concrete without damaging utility & water lines and post tension cables etc. In order to be able to achieve this goal, the best way is by using GPR utility tracking. ‘Ground penetrating radar’. In a nutshell, it can accurately penetrate hard surfaces such as concrete and find exactly where said utilities are so that you can work around them safely and efficiently without having to cause any unnecessary damage.
How Does GPR Work?
GRP locates elements underground via the emission of electromagnetic signals. These then penetrate substances such as concrete and will pinpoint anything that is below with direct surface hits. Following that these signals are reflected back to the GRP devise, displaying a clear and evident ‘map’ of below the surface.
You might wonder how the GPR can differentiate between different substances below the surface. This is basically determined by the strength or ‘level’ of the signals. So, the higher signals will indicate stronger obstructions such as steel or enclosed water, whereas lower levels indicate plastics.
What Are the 3 Main Benefits of Using GPR in Construction?
- Easily and efficiently locating utilities that are located below ground
- Taking safety precautions and avoiding hitting rebar support
- Easily and efficiently locating post-tension cable that lies within the concrete
Of course, the main benefit of using GPR is the fact that you can locate utilities before commencing any digging or concrete cutting. This makes life much easier and allows you to avoid cutting away unnecessarily until you find something. An excellent advantage which is certainly not to be snuffed at if you want to save time and work as efficiently as possible.
In addition to that, if you use GPR to locate utilities on one side of a concrete slab, you should be able to accurately gauge the location of a rebar or pipe will be on the other side if they’ve been laid symmetrically.
You can locate things like tension cables before having to begin the cutting or coring. Using GPR makes it possible to pinpoint how far said cables drape. This invariably makes the entire process much safer and more accurate for the construction crew before beginning the work.
It’s certainly a worthwhile investment. You can hire the experts who are well-versed in scanning concrete to find utilities. This will make life much easier for you with your construction projects. Don’t take any chances or cause any unnecessary damage to property when it can so easily be avoided with the correct approach.
