What is Ground Penetrating Radar?
Ground Penetrating Radar (GPR) uses high-frequency pulsed radio waves, between 10MHz – 3000MHz (UHF/VHF frequencies), to collect subsurface information to map both metallic and non-metallic structures within a variety of materials such as concrete, ground, rock, soil, walls or other structure.
How does GPR Work?
- Ground Penetrating Radar (GPR) equipment uses a transmitting antenna to radiate electromagnetic (EM) waves through the material.
- Under the surface, any objects with an abrupt change in electrical properties cause the electromagnetic waves to reflect, refract or scatter back to the the surface.
- The GPR receiver on the surfaces detects the reflected, refracted or scattered waves, processes the data and records it digitally in the monitor.
How Accurate is GPR?
Ground Penetrating Radar (GPR) can provide high quality images however as the surface materials are very dense and potentially complicated, GPR doesn’t work like a x-ray. The best analogy for how GPR appears, is a fish finder found on a boat.
What are the advantages of GPR?
Ground Penetrating Radar (GPR) has several key advantages over the alternative methods such as excavation. GPR advantages:
- Portable – GPR can be transported to any job site and operated in confined spaces
- Non-destructive – as GPR uses radio waves it won’t damage the surface being scanned
- Precise – our technicians control the exact horizontal and vertical positioning of the GPR scanner
- High resolution – subsurface imaging provides an accurate picture of the subsurface areas.
- Variety of materials – GPR can detect both non-metallic objects as well as metallic objects
- Inexpensive – GPR is quick to setup and operate compared to excavation
Slab Scan in Sydney
How a Slab Scan in Sydney Can Help Make Your Worksite a Safer Place
Before cutting into, coring, or conducting invasive work on concrete, you should always order a slab scan in Sydney. Whether you’re in charge of a trade team contracted to carry out renovation work or a project manager overseeing the work on your job site, examining a concrete slab with x–ray technology is the best choice that you can make for safety and efficiency.
A scan will contribute to your ability to complete a better job at a lower price and with fewer risks, and you can pass on satisfaction and value to your clients. At GPR Concrete Scanning & Coring, we provide a responsive, cost-effective service to equip your team with everything that they need to know to prioritise safety.
Why You Should Scan Before Drilling or Cutting
Looking inside a concrete slab has real-world importance. What are some of the key reasons why you should consider hiring services such as ours to carry out concrete slab scanning on-site?
- The knowledge that you gain through the process is critical for reducing your team’s risk of encountering hazards such as live electrical conduits, gas lines, or other infrastructure that may be encased in the slab. Just as you need to know what’s underground before you dig, you should know your slab before you cut.
- Renovation works carried out during the structure’s life could mean that previously-marked conduits no longer reside in those locations. A slab scan ensures that you have the most up-to-date picture possible.
- Plan better cutting operations. Once you understand the composition of the slab, it is simpler to create a plan of action for efficient work.
Get a Real-Time Report
In the past, GPR equipment was not as advanced, and analysis primarily took place after gathering information through concrete slab testing. There would typically be some delay between the scanning efforts and the delivery of a final report. At GPR Concrete Scanning & Coring, our technology enables us to view real-time results and produce a report much faster. Why does that matter?
- We reduce troublesome delays that can cause frustrating overruns for your project. Real-time reports enable you to quickly assess how soon you can move forward to the next phase of work.
- Your investment goes farther. Instead of waiting for days or weeks for a final report, you instantly see a valuable return on your spend when you receive detailed information in hand.
- Ask questions sooner. Is there something on your report that you find concerning or confusing? Now you can submit your inquiries and receive a faster response from our pros.
