AT ALL SCANNING SERVICES OUR MISSION IS TO ENSURE YOUR JOB RUNS SMOOTHLY WITH PRECISE CONCRETE X RAY RESULTS.
Concrete scanning prior to drilling can eliminate the probability of cutting through any potential live power or post tensioned cables and all structural elements within the slab.
Utility locating is necessary when cutting/digging through roads, driveways, footpaths and around buildings/houses. Avoid costly mistakes resulting from hitting assets... we're here to prevent this from happening.
Some of our scanning equipment we use to tackle all job types on a day to day basis. We're able to cover all sub-surface depths in concrete slabs, Beams, footings and underground utilities.
In some instances, post-tension ducts may appear like normal reo bars on the reflected GPR image. For reliable GPR scanning outcomes, most scenarios need further structural analysis.

In some instances, post-tension ducts may appear like normal reo bars on the reflected GPR image. For reliable GPR scanning outcomes, most scenarios need further structural analysis. For example: determine what type of slab is being scanned. In this case line scans and incremental scans were conducted and then it became clear as illustrated in the image above that the target was a post-tension(PT) duct. Unfortunately, many amateur scanning technicians can easily misinterpret this and mark the post-tensioned duct as a normal reo bar.
Cutting through a post-tensioned duct can prove to be quite disastrous and the structural integrity of the building will be compromised.
The purple arrows are pointing towards conduit in between Reo bars. The left and right sections of the image are two separate incremental scans on the same target. The left section on the image shows the top and bottom steel of the slab and the conduit is barely visible, however the right side of the image clearly shows the conduit in bet
The purple arrows are pointing towards conduit in between Reo bars. The left and right sections of the image are two separate incremental scans on the same target. The left section on the image shows the top and bottom steel of the slab and the conduit is barely visible, however the right side of the image clearly shows the conduit in between the top and bottom steel. This is why an incremental scan when using a concrete x ray machine is necessary.
The image above shows one of our scans with three conduits/live power and a PT (post-tension) duct which is to the right side of the conduits. It would be disastrous if any penetration occurred in this section of the slab. This is why concrete scanning is important, and engaging with an experienced scanning technician is even more important.
Our humble beginnings started when two friends joined forces, a builder and an electrician. We began to explore ways to make our jobs safer and easier when cutting/drilling through surfaces such as concrete. This led us to ground penetrating radar(GPR) also referred to as an x-ray machine. Understanding the science behind GPR! it became clear that our trade backgrounds were of significant help, when using GPR.
It seemed a new career path was on the horizon. In 2014 we had been researching GPR for almost a year and furthered our knowledge by completing GPR courses. At the time GPR training was quite limited to the point that it was almost non-existent.
Not long after we were lucky to be introduced to Dr. Richard Yelf a co-inventor of GPR (ground penetrating radar), who offered to give us expert training over a few days. In short Dr. Richard Yelf is a remarkable human being, and while he couldn't divulge all the secrets of the GPR technology, we were lucky to gain further insight into the art and science of GPR, and its practical applications. It was an invaluable experience, which no training course could have taught us.
In mid-2015 we started concrete scanning and fell in love with the industry, we haven't looked back since, having reached seven years in the industry, no job is too big or small or too difficult.
Is to make your job run according to plan with no mishaps. We use the most advanced scanning equipment and always up to date with required certification. Our clients can rest assure that every job is done through precision and ensuring you drill/cut safely. It is our priority to maintain customer satisfaction.
And remember "SCAN THE FLOOR BEFORE YOU CORE"
“All Scanning Services prides itself on identifying hazards and takes every precaution to ensure that safety is maintained for each project”

GPR is generally 85% accurate, however environmental factors may alter the results. As a rule of thumb GPR can be out by approximately 15% plus or minus the target, for example, the exact slab thickness is 200mm and GPR (ground penetrating radar) may display a reading of either 170mm or 230mm respectively. Please note that most scans are closer to 100% accuracy and variations are within single digit millimeters'.
Generally, if the client/ site contact has all proposed locations prepared and cleared from the underside of the slab, then the rule of thumb is around 4-5 corehole locations per hour, at scan dimensions of 600x600mm. However, factors may hinder time allowed per proposed location due to Reo density, Anomalies and type of slab.
Dial Before You Dig Plans will display how the assets should be positioned, however on the ground in reality! environmental and other factors can change the positioning of an asset. For example the asset may have to curve around tree roots which won't be shown on the plans. These variations can differ from centimeters to actual meters from line positioning and even depth positioning.
We strive to be in constant communication with our customers until the job is done. To book in for a concrete scan, or if you have questions or special requests, just drop us a line. We look forward to serving you!
