Premier Concrete Scanning Services in Western Australia

 TG Concrete Scanning uses the latest technology such as Ground Penetration Radar (GPR), GSSI Structure Scanner and Radio Detection to provide real time reporting completed onsite and emailed to you instantly with in depth and comprehensive scans of structures to assist engineers, builders and developers.

Not knowing what lies beneath concrete creates uncertainty. This uncertainty can lead to blown out budgets and delayed projects.

Precision Technology at Your Service

TG concrete Scanning locates post tension cables, map reinforcement, provide slab thickness, locate live services
and then present you with the required information about your structure. TG Concrete Scanning also locate in ground services and items to assist in digging or excavating.

Our Equipment

GSSI STRUCTURESCAN MINI XT

The StructureScan Mini XT is GSSI’s newest generation of the very popular all-in-one GPR systems. The StructureScan Mini XT offers a 2.7 GHz antenna for superior target resolution and can reach depths of 20 inches (50 cm). Ideal for locating rebar, conduits, post-tension cables, voids, and real time determination of concrete slab thickness.

Typical Uses for StructureScan Mini Include:

  • Concrete inspection to locate metallic and non-metallic targets in walls, floors and ceilings.
  • Structure inspection on bridges, monuments, walls, towers, tunnels, balconies, garages and decks.


  • Measure slab thickness and Void location.
  • Condition assessment to map relative concrete condition for rehab planning

HILTI PX-10 TRANSPOINTER (HOLE LOCATOR)

The Hilti PX-10 Transpointer hole locator is used when needing to transfer the starting point for drilling through-holes to the other side. Wall and ceiling thickness measurement for easy selection of the right drill bit or core bit length. To determine drill bit exit position and transfer drilling positions when drilling through walls and ceilings in concrete and masonry.

Position point can be transposed through floors, ceiling and walls – allowing any drilling work to be carried out quickly and efficiently. Measures wall thickness automatically saving time by skipping trial-and-error pilot drilling.

RADIO DETECTION RD7200

The RD7200 Precision Underground Utilities Locator is used for accurate and fast locating of underground cables and pipes.

HDR Easy Pro Ground Penetrating Radar

The EasyLocator proGround Penetration Radar (GPR) is a non-destructive testing method and for that reason it has various limitations and restrictions. The GPR concrete unit has a maximum depth of 400mm in ideal conditions like concrete structures with minimal steel. The depths that are collected for the located targets are an approximate and maybe slightly shallower or deeper than stated. Targets are located by the centre of the GPR units where the antenna is situated.

Targets are located by the centre of the GPR units where the antenna is situated. The centre of the antenna needs to be able to roll over the target perpendicular, this means GPR data cannot be collected within a 100mm from any wall or obstruction on the concrete scanning unit and 400mm from any obstruction on the utility locating detection unit.

    The GPR units must have the wheels rolling in order to operate and collect data. There is a small gap between the bottom of the concrete scanning unit and the ground, which means the surface needs to be somewhat smooth. 


    The GPR scanning units cannot penetrate through metallic objects or through water.


    GPR can locate voids however cannot image anything within or beyond a void.


    GPR scanning units cannot establish the material or the diameter of the target/ object.


    GPR concrete scanning unit cannot locate in slab services if they are below the steel reinforcement bars.


    The 50Hz electromagnetic sensor and the pipe and cable locator cannot detect inactive or low voltage cables within the concrete structure, they must be energised at the time of the scan.


    Locating electrical cables can only be accurate when connected and traced from a known point of existence.


    The electromagnetic field can be broad when detecting an electrical current, this means when marking the location of the electrical cable will not be exact.


    When scanning for services with the electromagnetic locator, the services can be within the concrete slab or below the concrete slab.


    With a GPR Scan, TG Concrete Scanning are able to provide a detailed report with real-time data, revealing critical components within concrete and other structures.
