SUE & utility mapping

Structural & pavement assessment

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.

Overview

The PHASCAN has 32/128 Pulser/Receiver channels for Phased Array. There is also high-performance TOFD detection using dual independent channels
Calibration is very convenient to implement and can be verified for each beam.
An Embedded focal law calculator allows:
- 4 modes of scanning: linear, sectorial, depth and static.
- True Depth, sound path, projection, and focal plane with 4 variations of focus types
- Display modes: A/S/B/C
Multiple group for parallel scanning- which is the equivalent of multiple instruments working simultaneously.
Negative square-wave emission, with resolution up to 2.5ns, PRF up to 20KHz.
A 10.4'' TFT LCD colour touch screen, with resolution 800*600 pixel.

Features

Convenient Setup Wizard

Materials selection, with a velocity database
Workpiece configuration for flat or curved surfaces.
Library of probes and wedges for fast selection as well as user-defined options
Multiple options for scanning modes and depth are available with the same probe simultaneously

Accurate Calibration

Every beam is a single channel detector, ensuring calibration of each channel.
Interactive menus allow operators to quickly adjust the velocity, wedge delay and sensitivity calibration.

Powerful Data Analysis

Measurement and Reference cursors can be used to quantify defects that are found and this information can be used to generate reports.
Interactive analysis in all modes: A, B, S and C-scan. Defect analysis is, therefore, more precise.
All measurement results are obtainable online. An off-line analysis is performed on the saved complete A-scan.

Excellent Focus Imaging

Precise image resolution
Angle accuracy of up to 0.1 °.
Focus type can be set which more clearly shows defects

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
