- UtilityScan HS (High-Speed): Ideal for highway and rail corridors where fast-paced coverage is required without compromising depth resolution. Offers GPS integration and onboard data logging.
- RoadScan System: Designed for pavement structure analysis, including layer thickness and defect location in tarmac and concrete roads. Used in asset maintenance and resurfacing schemes.
- RADAN Software Suite: Used across all our GSSI data workflows for post-processing, depth calibration, and export into CAD or BIM environments. Enables full survey traceability and client-ready deliverables.
Why We Use GSSI
GSSI systems are trusted worldwide for their signal clarity, robust construction, and software interoperability. At NDTScan, we rely on GSSI because their radar performance holds up in diverse UK site conditions — from reinforced concrete buildings to contaminated ground. The real-time feedback, multi-layer data capture, and PAS128 survey readiness make GSSI the backbone of our scanning operations.
Other Tools in Use
In specific cases, we also deploy Mala GPR and IDS GeoRadar systems — particularly where extreme depth, 3D rendering, or radar interferometry is required. However, GSSI remains our preferred platform for concrete inspection, utility detection, and sub-surface decision-making across the built environment.
Accurate Subsurface Intelligence Without Disruption
At NDTScan, we use GSSI ground-penetrating radar UK systems to capture subsurface data with clarity, speed, and zero physical disruption. Whether verifying slab integrity before drilling or locating buried services beneath an urban pavement, our GSSI units provide high-resolution results in real time — reducing guesswork, risk, and rework across civil engineering, construction, and infrastructure inspection.
Every scan is traceable, calibrated, and integrated into digital formats — ready for review by engineers, project managers, or compliance authorities. With instant visual feedback, we can adapt in real time to site conditions, asset complexity, or emerging scan anomalies. GSSI gives us the confidence to work in live environments and time-sensitive scenarios — delivering actionable results that support safe, compliant, and cost-effective decision-making.
Supporting Safe Access, Design, and Construction Planning
One of the most valuable applications of GSSI ground-penetrating radar is pre-construction risk mitigation. Before coring, cutting, or drilling into slabs or pavements, we use handheld and cart-based GSSI units to detect and mark subsurface hazards — from rebar and conduits to post-tension cables and embedded steel. This protects workers, avoids utility strikes, and preserves structural integrity during intrusive works.
We also support early-stage project planning through full-slab or site-wide GPR surveys — mapping out known and unknown subsurface features so that design teams, architects, and contractors can work with complete confidence. By detecting voids, delamination, undocumented utilities, or legacy foundations, we help eliminate uncertainty and avoid costly surprises mid-project.
Versatile Solutions for Every Site Condition
Our range of GSSI radar systems allows us to adapt to the specific demands of each site — whether that means fast highway scanning, tight indoor corridors, deep utility tracking, or highly reinforced concrete.
-
StructureScan Mini XT is our frontline tool for high-resolution concrete scanning. Lightweight, wireless, and rugged, it delivers fast data on reinforcement layout, cable runs, slab thickness, and shallow voids. Ideal for lift shafts, floor slabs, suspended soffits, and wall cores.
-
StructureScan Pro steps in for larger slabs or elevated safety zones. Its increased antenna size and multiple-channel capability give us higher coverage rates with no loss of resolution. Commonly used on bridge decks, industrial floors, podium slabs, and mezzanines.
-
UtilityScan DF gives us the best of both worlds — a dual-frequency radar that captures shallow service lines and deeper structural features in a single pass. This is crucial in congested city centres, redevelopment zones, or brownfield sites with mixed-depth infrastructure.
-
UtilityScan HS is our tool of choice when coverage speed matters. Designed for long-range environments such as highways, airports, or railway corridors, it provides high-resolution imaging without slowing down the inspection team.
-
RoadScan System enables non-destructive road condition assessment — including pavement layer depth, delamination, and void mapping — supporting long-term asset maintenance and resurfacing planning.
No matter the site — dry, wet, reinforced, filled, or unstable — GSSI radar units adapt with adjustable frequencies, interchangeable antennae, and advanced digital filtering to deliver clear and usable data.
Digital Outputs for Engineering and Compliance
GSSI radar data captured by NDTScan is processed through the RADAN Software Suite, a powerful platform for depth calibration, data layering, filtering, and export. This ensures all GPR scans meet the documentation and integration needs of today’s engineering environments.
We deliver reports and outputs in:
-
CAD-ready plan views with marked scan targets
-
Depth slices and signal profile views (B-scans)
-
3D visualisations where site conditions allow
-
PDF reports with annotated screenshots and interpretation
-
DXF, DWG, and BIM-compatible formats for design use
Every deliverable is georeferenced where required and supported by metadata including equipment ID, scan settings, environmental notes, and operator details — maintaining full audit traceability and PAS128 compliance where applicable.
For utility mapping projects, we also align GPR data with electromagnetic location (EML) and site records to produce composite utility drawings — enhancing safety, supporting permit requests, and streamlining construction workflows.

Why GSSI Sets the Standard for Subsurface Clarity
There are many GPR systems available — but few offer the field reliability, data quality, and ecosystem integration of GSSI. That’s why we continue to invest in their platforms across our handheld, cart-based, and highway-capable radar systems.
GSSI units are rugged enough for live construction sites, yet precise enough for forensic-level concrete inspection. Their modular design, battery life, real-time visualisation, and post-processing power make them the backbone of NDTScan’s scanning operations.
In high-risk environments, under time pressure, or in regulatory-driven projects — we trust GSSI to deliver.
