Our Slab Scan Technology

What makes our slab scan services so effective? We use the latest, state of the art technology to ensure our customers get the best results consistently.


We are constantly updating our equipment and technology to ensure that we are keeping up with what our customers want and need. We focus on providing a full service slab scan with products and technology that gets accurate results.

High frequency concrete slab scan – Ground Penetrating Radar (GPR)

Prior to cutting, coring or drilling of concrete slabs and structures, a safe and reliable, non-destructive means of inspecting work surface areas to locate and identify hidden features is needed to prevent damage to machinery, danger to the operator or the structure itself during these works. High frequency GPR is best suited for these concrete surveys. By using state of the art GPR scanners we are able to accurately locate and report on features present in the concrete structure to a depth of 300 to 400 millimeters (mm). The Mala CX-12 concrete scanner can detect both ferrous and non-ferrous objects within the concrete. The unit has a built-in EM detector that is able to detect mains cables as well.

We do offer a 3D concrete slab scan that provides a detailed surveys and report on the surface area..

Ground Penetrating Radar (GPR) low frequency used to locate power/signal cables and both ferrous and non-ferrous pipes in the ground and other sub-surfaces

Low frequency GPR is used to survey soil, tarmacs and other non-concrete sub surfaces. It is particularly useful for detecting plastic and other non-ferrous objects, which may be impossible to detect using other technologies. The low frequency ground GPR can comfortably work to a depth of around 3 to 4 meters (m) dependent on sub-surface conditions. Refer to the “Services” page for more information on applications.

See the Ground Penetrating Radar (GPR) video below for an explanation on how this technology works.

Electromagnetic Slab Scan – (EM) Detection 

Our electro magnetic slab scan techniques are used to locate power/telecom cables, ferrous pipes and some non-ferrous pipes if a conductive rod can be inserted

We use only the best EM scanners for cable and pipe location in non-concrete sub surfaces. Locating plastic pipes can be challenging if no tracer wire is present. In extreme cases where we cannot use low frequency GPR, we are able to insert a conductive rod into the plastic pipe if the pipe opening is accessible.

In the case of ferrous pipes we induce a signal on that pipe and are then able to locate the pipe by scanning for the unique injected frequency.

Mains and Telco cables can be detected in most instances by scanning for the unique frequencies emitted by the cables.

In the case of fibre optic cables, we have to insert a conductive rod into the conduit to trace.

See the Locating Utilities, electromagnetic detection video below to see how this technology works.

Latest Technologies

Sniper Concrete Scanning is always on the lookout for new concrete scanning and cable/pipe locating technologies that will enhance  and improve our technical ability and our service to our customers. Once we identify potential new technologies, we thoroughly test and  trial these technologies to ensure that they are able to deliver the desired results before implementation.

No application is limited to any single technology when it comes to cable and pipe locating. We use a combination of all of the latest  technologies to ensure that we achieve the most optimum results for our customers.
