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.

SuperSonix Ambient UT Gel

SuperSoniX is an enhanced performance couplant with a broad operating range, slow evaporation rate and gel viscosity that remains in place.

  • Gel viscosity remains in place for overhead and vertical surfaces
  • Broad operating range for a water-based couplant
  • Slow drying
  • Salt-stable viscosity
  • Water-soluble
  • Environmental and operator friendly

Contains glycerin. Not for aluminum aircraft inspections.

UltraSonix

UltraSoniX is a high-performance couplant, available in medium viscosity, ideal for spreading.

  • -12°C to 104°C temperature range for most flaw detection and thickness gauging applications.
  • Water-soluble: easy to remove Environment and operator-friendly – no formaldehyde, nitrates, nitrites, or glycol ethers.
  • Lower residue than most UT couplants.
  • No glycerin as required for carbon fiber composites.

Removal: Wipe with wet or dry paper or cloth rag or water wash.

EchoMix® Single Powder

Single packet powdered UT couplants provide an economical solution for travel, remote access inspections and storage limitations.

EchoMix Single is a one-part (one packet) powder, easily mixed in ambient water in five minutes, providing a strong, continuous coupling film that adheres well to vertical and overhead surfaces. Single mix packet, one step mixing.

  • Easiest mixing powder couplant
  • One packet
  • Less residue
  • Blue mixing tracer
  • Salt stable – will not thin with corrosion salts or in marine or highway environments
  • Fast, easy removal with water
  • Compact for shipping and storage
  • Easy mixing, fast gel time in ambient water

Removal: Remove with a dry rag, water and brush or pressure washer.

Air Bubbles: All powder couplants will form small air bubbles after mixing if water is not de-aired. These small bubbles usually do not negatively affect the use of the couplant and will dissipate in 3-4 days. If an air bubble-free couplant is desired immediately, use hot water and allow to stand overnight; then proceed with adding the powder couplant.

The Blue Color is a visual marker to ensure uniform distribution of the corrosion inhibitor by encouraging thorough mixing.

VersaSonic High Temperature Couplant

VersaSonic® is Echo Ultrasonics' most versatile couplant, from high temperature on turbine rotors to extreme weather inspections.  VersaSonic is a low-toxicity, biodegradable couplant that does NOT contain peanut oil.

  • Instantaneous ultrasonic response (does not contain plastic powders which delay ultrasonic conduction)
  • Excellent high temperature transducer lubricant, extends transducer life
  • Multiple viscosities covering flaw, corrosion mapping and thickness gauging at high and low temperatures and in mud, snow and rain
  • Ambient and low temperature coupling where corrosion inhibition is critical
  • Excellent corrosion inhibitor. Provides non-toxic, superior, long-term corrosion inhibition for steel and cast iron and is compatible with other metals and most plastics. VersaSonic may be left in place unless it will interfere with subsequent manufacturing operations such as painting or electroplating
  • Low environmental impact. Contains no perfluorocarbons, silicones, peanut or tree nut oils.

Removal: wipe with paper or cloth rag. If complete removal is required, dish detergent and water or a chemical degreaser can be used.

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.
