Collect high-density, georeferenced GPR data across wide areas and view the subsurface in 3D as you scan. Choose the GX2 array for SUE and utility mapping, or the GX1 array for structural, bridge and pavement investigations.
Best suited to:
Best suited to:
Recommended array: GX2
Recommended array: GX1
Cover more ground
Collect multiple parallel profiles in one pass instead of uilding a grid line by line.
See results during acquisition
View georeferenced radargrams and time-slice information in the field rather than waiting until the data is returned to the office.
Produce repeatable mapped data
Combine wheel-positioned GPR data with GNSS, project coordinates and survey linework.
Use one platform for two very different applications
Exchange GX1 and GX2 arrays without purchasing two complete cart platforms.
The GX2 transforms the GS9000 into a high-density subsurface utility mapping system. Its 11-channel, low-frequency GPR array captures an 83 cm-wide swath in each pass, helping operators detect and map buried pipes, ducts, cables, voids and other subsurface features. Live georeferenced data lets SUE teams review coverage on site and produce accurate CAD, GIS and project-coordinate deliverables.
1. Plan the survey
Load satellite imagery, CAD information, project coordinates or survey control.
2. Collect dense multichannel data
Survey an approximately 0.82 m-wide swath with 11 channels in each pass.
3. Review data live
Examine radargrams, georeferenced time slices and marked features while still on site.
4. Interpret and digitise
Add points, linework, tags, photographs and field observations.
5. Process and deliver
Merge survey areas, apply processing and export mapped information for the customer’s CAD, GIS or reporting workflow.

It is now easier than ever to verify the thickness and integrity of concrete flatwork. Drilling, coring and excavations are now obsolete. Save buckets of time, effort and money by simply using the CTG-2 instead.
No specialized knowledge or training is required. The CTG-2 comes ready to use straight out of the case, with inbuilt default parameters. Great accuracy is achieved through calibrating against your specific concrete type.
Use your own Windows 7, 8 or 10 Laptop/Tablet* and simply connect the CTG-2 to directly view live measurement recordings, via the WinCTG-2 Software. Thickness and flaw information can also easily be transferred to spreadsheets or to your reports.
*Please note Tablet is not included
Impact Echo testing can be used for:
Concrete Thickness
Impact Echo relies on an estimation of p-wave velocity through concrete to determine thickness. Thickness measurements are obtained when the test head is applied to the concrete surface and triggered.
Calibration Process
Default settings are customised to standard concrete and generally produce results within ±10% accuracy. Accuracy of ±2% is achieved when the p-wave velocity is calibrated on-site against a slab with known thickness.
Data Transfer
WinCTG-2 software works alongside Windows 7 or 8, converting frequency and thickness data into most spreadsheet formats for further analysis and reporting.
WinCTG-2 Analysis Software
The Windows based WinCTG-2 allows data and measurement setting review. Customised test grids can be set up using X and Y coordinates from your point of reference. Live field data can be viewed while testing.

The GX1 transforms the GS9000 into a high-resolution structural assessment system for concrete slabs, bridge decks and pavements. Its dense, dual-polarisation array captures detailed 3D data across wide areas, supporting reinforcement and cover mapping, moisture and deterioration assessment, and analysis of asphalt and pavement layers. Live visualisation helps confirm survey coverage on site, while post-processing tools produce clear, report-ready condition maps.
1. Define the inspection area
Import the structure, bridge, pavement or survey background.
2. Collect closely spaced profiles
Capture 35 longitudinal and 15 cross-polarised channels with dense spacing.
3. Review coverage in the field
Use live radargrams and time slices to confirm that the required area has been captured.
4. Process the dataset
Apply velocity, gain, background removal, migration, filtering and topographic correction as appropriate.
5. Generate diagnostic maps
Create depth slices, reinforcement maps, layer information or application-specific condition maps.
6. Integrate with the engineering assessment
Export figures, mapped anomalies and raw data for inclusion in the engineer’s final interpretation and report.
