GS9000 Multichannel GPR for 3D Utility Mapping and Structural Assessment

Overview | GX1 vs GX2 | SUE & Utilities | Structures & Pavements | Software & Outputs | Case Studies | Specifications | Support

Discuss Your Application

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:

  • Subsurface utility engineering
  • Utility locating and mapping
  • Civil and survey contractors
  • Road and corridor investigations
  • Void and subsurface anomaly surveys

Best suited to:

  • Bridge-deck investigations
  • Concrete cover and moisture mapping
  • Pavement and asphalt-layer assessment
  • Reinforcement mapping
  • Structural deterioration surveys

Recommended array: GX2

Recommended array: GX1

Why use the GS9000 instead of a conventional single-channel GPR?

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.

High-density 3D GPR mapping for SUE and utility investigations

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.

  • Utility corridor mapping
  • Detection of pipes, ducts and cables
  • Mapping non-conductive services that may not respond to electromagnetic locating
  • Congested service investigations
  • Road-crossing and easement surveys
  • Potential void and cavity investigation
  • Pre-excavation and design-stage surveys
  • Utility mapping to project or local coordinates

The SUE field workflow

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.

All devices in the range include a 320 x 240 pixel display, control of gain and a measuring range between 0.6 to 508 mm depending upon material tested. TG4500D models add Thru-paint testing and TG4500DL also adds a data logging functionality.

Thickness gauges are widely used in the Oil & Gas, Petrochemical, power generation, shipping & manufacturing, pressure vessels and storage tanks.

Performance Features

Common applications include metals (such as steel, cast iron, aluminium, copper, etc), plastic, ceramic, glass, fibre-glass and other ultrasonic good conductors.

  • Can be used with various dual crystal probes in different sizes and frequencies.
  • Flexible Calibration Function for single point calibration or two point calibration can correct the error of the system automatically.
  • By using known specimen thickness, the sound velocity can be measured, which will improve the measurement accuracy.
  • Coupled with prompt, low voltage-tips on the screen.
  • EL backlight display function: for measurement in poor light conditions.
  • Dump energy indicator function: to display the real time dump energy of the batteries.
  • Shutdown mode: manual and automatic shutdown features are helpful for increasing battery life.
  • Compact size is able to deliver high reliability, ability to handle vibration and the typical Australian harsh conditions.

Applications

Various parts of instruments, to provide fast, accurate measurement of the plate and the parts processing table. Another important application of this watch is monitoring the production equipment of all kinds of piping and pressure vessel, in the use of monitor to the refinement degree. Can be widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and other fields.

Why the GS9000 matters for SUE businesses

  • Increase area covered per field day
  • Reduce the number of manually positioned survey lines
  • Improve coverage in congested corridors
  • Review coverage before leaving site
  • Produce higher-value mapped deliverables
  • Combine GPR and GNSS in one workflow
  • Retain raw data for later reinterpretation
  • Expand from locating into mapping and subsurface modelling

High-resolution multichannel GPR for structures, bridges and pavements

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.

  • Bridge-deck reinforcement and condition mapping
  • Concrete-cover mapping
  • Reinforcement layout and spacing
  • Moisture-related and deterioration mapping
  • Asphalt and pavement-layer thickness
  • Road and runway investigations
  • Detection of embedded features
  • Large-area concrete-slab investigations
  • Comparative and repeat surveys

The structural assessment workflow

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.

When to use the GS9000 rather than a handheld GPR

Use a handheld or single-channel GPR when…

Use the GS9000 when…

  • The inspection area is small
  • You need local marking before drilling
  • Rapid spot checks are sufficient
  • Manoeuvrability is the main priority
  • The output is primarily site marking
  • Large areas must be covered
  • A completely mapped dataset is required
  • Large datasets are required
  • Productivity and spatial continuity are priorities
  • The output must support reporting or engineering interpretation
