Maintaining the integrity of the concrete that is one of the most important elements that needs to be considered when it comes to dam maintenance and concrete scanning. It is also vital for many other processes. This is why a thorough understanding of the entire make-up of the concrete is of significant importance where the builders are operating powerful equipment and working at considerable heights.
For instance, during the reinforcement work for the original Cotter Dam that had been constructed in the year 1912, the workers had to abseil down the entire dam wall to be able to check if there were any cracks in the brittle concrete, they didn’t have ground penetrating radar systems like we do today. There was a need for hundreds of Hilti anchors at different points of the wall to be able to attach to the abseiling equipment.
The drill holes of the anchors had to be positioned correctly in order to avoid any damages to the rebar and prevent any costly delays. The PS200 detection system of the Hilti Ferroscan was then used to rule out any possibility of damages to the steel reinforcement.
Furthermore, the cordless Ferroscan system makes use of a monitor unit, scanner and PROFIS software for the PC in order to determine the number of rebar that are present, their depths, diameters and positions.
The magnetic resonance principle is employed by the system to be able to detect the reinforcing metal bars. A magnetic field is generated by the concrete slab scanner and it interprets the variations of the magnetic resonance that are caused by the reinforcing bars.
After the scanner passes over the surface of the structure, the reinforcing bars’ position would be marked directly onto the concrete and the data that is applicable would be recorded and immediately transferred on site to the monitor unit which is portable so as to enable viewing and evaluation.
A reliable image of the concealed reinforcements would be provided to the workers simply by concrete scanning melbourne over the structure and the surface. Then, they would correctly identify the suitable rebar-free sites which would be where the holes would be drilled and the anchors would be inserted.
The best practice are followed for reinforcing, cutting and drilling on the construction projects so as to ensure integrity of the structures and to help the builders enhance efficiency and accuracy.
The non-destructive concrete technology of today allows the builders to perfectly drill into the correct position the first time around and avoid any damaging of the structure. Before they build, it’s best to use concrete scanning in melbourne to see what’s under the surface. It is all due to the fact they would have instant access to critical information of what lies beneath the surface of the structure.
Understanding the depth and position of the rebar allows the builders to keep the functionality of the structure intact which is only possible using concrete radar scanning, and it also makes reinforcements possible. In turn, it allows water to continue being provided to the masses and helps preserve it for future generations to come. GPR and other technologies are the only way to go.
