As the direct successor to the Galvapulse the CorroMap provides easy to use half-cell potential and galvanostatic pulse corrosion rate measurements.

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:
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 CorroMap is a rapid, non-destructive technique for the evaluation of reinforcement half-cell potentials and corrosion rates. It maps the contour plots of half cell potential and resistance in colour on the screen and for transfer to PC.
The CorroMap is a lightweight system with rechargeable batteries for optimum portability and is designed to be operated by one man. It offers reliable evaluation of reinforcement corrosion also in wet, carbonated or inhibitor treated concrete so that the Half-cell potential and electrical resistance to the cover layer are given.
The system will also take galvanostatic pulse measurements which are an indication of the rate of corrosion of the reinforcing steel.
The equipment comes with a Lightweight electrode and a hand held computer pre-installed with easy to operate software. A durable steel ring for applying the current field to the reinforcement allows for measurements possible on uneven and curved surfaces with a replaceable sponge.
The system also includes a variety of connections and cables to make obtaining reinforcement contact as simple as possible.
The CorroMap is typically used in connection with:
The included software for the PISON workabout Pro3 is used to set up mapping parameters and record resistance, half-potential and corrosion rate data.
This system allows a grid of any size to be established, a data collection procedure defined and data quality parameters set below which information will not be recorded. Data is exportable to excel format.

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.
