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.

The ResiPod is a fully integrated 4-point Wenner probe, used to perform resistivity measurements on concrete as a non-destructive test.

Proceq's Resipod is extremely fast and stable and packaged in a robust, waterproof housing designed to operate in a demanding site environment.

Resipod Models and Probe Spacing

Resistivity Measurement, Resistivity Meter, Concrete Resistivity, resipod, concrete resistivity test

Wider probe spacings provide a more consistent reading when measuring on an inhomogeneous material like concrete. However, if the spacing is too wide, there is more danger of the measurement being affected by the reinforcement steel. The industry standard 50 mm probe spacing has long been seen as a good compromise.

The 38mm model is designed specifically to comply with the AASHTO standard (under development) for “Surface Resistivity Indication of Concrete’s Ability to Resist Chloride Ion Penetration”.

The contact extension cable kit can also be used to attain variable spacing for the contacts. Spacing from 20-85mm can be achieved using the kit, which is bought as an optional accessory.

Features

Despite being extremely simple to use, ResiPod provides a variety of features that are unique in a concrete surface resistivity instrument.

  • Fully integrated surface resistivity instrument
  • Wide measuring range (0 to ca. 1000 kΩcm)
  • Fast and accurate delivery of measuring results
  • Highest resolution available for a surface resistivity instrument
  • Meets the AASHTO standard (38mm spacing) (standard under development)
  • Current flow indication and poor contact indication
  • Hold, save and delete function, with onboard memory
  • USB connection and dedicated PC software
  • Designed to float (waterproof according to IPX7)
  • Allows variable probe spacing to be set
  • Allows replacement of standard tips with accessories

Display

The display of the ResiPod shows all necessary information while acquiring data on site.

Resistivity Measurement, Resistivity Meter, Concrete Resistivity, resipod, concrete resistivity test
  • Measured resistivity
  • Battery status
  • Range indication
  • Current indication 20%, 40%, 60%, 80%, 100%
  • Indication of scaled reading

Indication of Poor Connection

A good connection between the instrument and the concrete surface is the most important factor for obtaining a reliable measurement. ResiPod automatically detects a poor connection and alerts the user.

Resipod Link Software

The collected measurement values can then be analysed comfortably with the ResiPod Link PC tool.

System requirements: Windows XP, Windows  Vista, Windows 7, USB-Connector. An internet connection is necessary for soft- and firmware (using Pq Upgrade) updates if available.

Bulk Resistivity Module

Resistivity Measurement, Resistivity Meter, Concrete Resistivity, resipod, concrete resistivity test

The ResiPod can now be upgraded to take bulk resistivity of 102 x 204 mm cylinders using the Bulk Resistivity Module. Bulk Resistivity measurements are taken in such a way that the whole of the cylinder informs the result and are able to be correlated to surface resistivity measurements. The module includes 2 metal and sponge contacts and a convenient stand for the ResiPod.

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.

  • 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
