The UniWest Tie Bolt Inspection System enables complete and fast inspection of all standard sized tie bolts with a single instrument.

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.
The strength of UniWest's tie-bolt inspection system is in the simplicity of the design. Using both gravity and thread angle, the probe is driven along the thread pattern and then manually manipulated along the rest of the shank and head radius. The entire inspection can be completed in less than seven seconds. There are no expensive fixtures to replace. All standard size tie bolts can be inspected with this one instrument. Special modifications can be made to fit over and undersized bolts. Tie-bolts are placed in the system bed on two rotating cylinders and rapidly rotated in a clockwise direction on a series of embedded rubber o-rings. An X–Y ball slide positions the probe for optimum inspection along the length of the tie-bolt. Probe travel stops at the end of the thread pattern and free spins. The operator then manually moves the probe along the shank of the bolt and positions it at a 45 degree angle for inspection of the radius under the bolt head. A single probe can accommodate a variety of bolts for proper centering of the coils for flaw detection. The probe body is slotted to fit into the probe holder and locked into place by a set screw. The system is shown with the UniWest US-454 EddyView® test instrument with both strip chart and impedance plane display of the indications. This allows easy and uncomplicated signal interpretation by the operator.

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.
