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.

The Auxiliary testing frame is used for the measurement of deflection during the flexure test on 100x100x400/500 mm or 150x150x500/600 mm beams.
The auxiliary testing frames can be used on all UTEST flexural testing frames.

The test assembly is used for center or two-point loading flexural tests on 100 mm or 150 mm concrete beams.

Two lower rollers and one upper roller of 38 mm dia. and 610 mm length.
Suitable for flexural testing of concrete pavers and terrazzo tiles, natural stone kerbs and slabs.

The set includes two lower rollers 38 mm dia. x 610 mm long and 40 mm dia and an upper loading piston with ball seating assembly.

With two 50 mm high accurate displacement transducer. Outer dimensions 700x700 mm and 100x100 mm square section loading punch.

UTC-4512 comprises an upper platen with ball seating assembly included and a lower platen both of 165 mm diameter.
Distance pieces need to be added to an order to allow proper spacing.

Flexural test device for center-point or two-point (third-point ASTM) loading flexural tests on concrete beams of 100 x 100 x 400-500 mm or 150 x 150 x 600 - 750 mm.
Consisting of two upper rollers and two lower rollers of 38 mm dia. and 160 mm length. Double upper bearer for four point test. Total height is 330 mm when adjusted for 150 mm beams and 290 mm for 100 mm beams.

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.
