The Importance of Concrete Scanning

Why is concrete scanning necessary?
It demands caution to have concrete structures drilled, cored, and cut. This is done to find hidden features under the concrete that may cause problems within the structure and the machinery. If these features are not addressed, these may harm the operator himself as well as the people who work in the vicinity.
We make sure that construction professionals have the safe and accurate means of inspecting concrete areas to locate, identify, and unearth hidden features.
How is the testing done?
The first step is that we try to locate the reinforcement and also the post-tensioned tendons found in walls and floors. The different antennas we have also detect and locate different features. For instance the 1600 MHz antenna is intended to find PVC pipes and also those voids that are within the walls and even slabs that are up to 0.5 of a meter. Inconsistencies are also checked like honeycombing, cracks, and voids that are found in walls and in between slabs. Locating targets under the slabs and also behind walls is done as well as verifying thick slabs, verifying areas within slabs and walls if they are safe for drilling, coring, and cutting. We also locate the penetration exit points accurately to get away from beams and thickenings within slabs. We also measure the steel mesh and the concrete cover for reinforcement on the work site. We can also accurately locate and determine dead and alive services found under and within the slabs. Of course, everything will not be complete without us providing a comprehensive report.
What is the competitive edge in our services?
It is our aim that workers from the work site can go home safe, and that deadlines are met, and profits are maximized of course without loss of time and most importantly loss of life. Slabs have to be checked while workers are working on them for purposes of worker safety and work downtime. For instance it would be fatal for a worker to accidentally cut a live wire. This can cause downtime in work as well which can cost a lot and as a result the deadlines of the project might not be met.
Why do we use GPR system?
We use the GPR system since it is non-intrusive and non-destructive and it can be done quickly and efficiently without any work obstruction and inconvenience on the workers. This method is known to produce faster results, 2D imaging and projection, and also it is safe to use in public areas. This system also works efficiently on large areas, and the GPR produces real time reports and images that the concrete scanner technician can analyze on the site itself. This system can save time and money for our clients and ensure safety for  our workers.

Concrete Scanning

We provide highly accurate professional concrete scanning services. Concrete scanning is a requirement before concrete is drilled, cut, or cored. Through the results of concrete scanning, contractors, builders, and engineers will have the accurate and well-researched and interpreted subsurface data that will ensure these professionals can make the right decisions regarding their projects. With concrete scanning, all rebar, utilities, or any hidden features are identified so that damages during and after the construction process can be prevented. That also means preventing expensive downtime, errors, injury and even death.
What is GPR System?
The GPR System means Concrete Imaging Ground Penetrating Radar system. It is also known as “concrete x-ray” service. This is intended for investigating and imaging concrete and other structures in a way that is not destructive. Through the use of GPR or x-ray imaging, you can scan the concrete inner structure safely and be able to present the date in real time and through the in-the-box data acquisition, analysis, and display.
We at Expert Office Fitouts make use of cutting edge technology developed by the world’s leading manufacturer of GPR. This is made to locate and record accurate details of conduits and services. Compared to traditional scanning procedure, GPR allows the technicians to work on the other trades without evacuating or coming up with an exclusion zone.
With GPR system, the energy that comes out from the GPR unit is many times lower than the ones emitted by the mobile phone. This means that relocation is not necessary since everyone is not at risk of being exposed to harmful chemicals. GPR also makes it easier and more convenient to scan large areas. The GPR can create one or more scrolling images that can come up with a sectional view of the test area. These can be put together to form virtual 3D model much like an MRI at the hospital.
GPR system can be applied to the following: post tension cables, stressing cables, voiding detection and location, location of reinforcing support structure/rio bars, location of nonmetallic items, etc.
This can create images on all of the following: phone lines, metallic gas pipelines, fibre optic or data cables, storm water pipes, PVC water mains, terracotta sewers, etc. Even our antennas can help find geological targets just like changes in the subsoil consistency and in its composition which is needed for environmental surveys and mining purposes.
