GPR
Accurate Mapping of Buried Services for Planning, Safety & Compliance
Underground Detection Services
Arthian delivers high-accuracy utility mapping and ground penetrating radar (GPR) surveys for industrial, infrastructure and high-hazard sites across the UK. Our surveys help clients avoid costly utility strikes, reduce health and safety risks, and comply with planning, CDM and permitting requirements.
We follow the latest industry standards, including PAS128, and provide confidence-rated data for design, excavation and construction.
Utility Mapping & GRP Surveys – The Basics
We offer a comprehensive GPR service consultancy.
What We Detect
- Water, gas and telecoms pipes
- Electric cables and ducting
- Drainage and culverts
- Non-metallic services (e.g. plastic, clay, concrete)
- Voids, tanks and buried structures
- Unknown or undocumented utilities
Survey Types & Standards
Our surveys are delivered to PAS128 and TSA standards and include:
- Type C: Site reconnaissance and surface feature validation
- Type B: Geophysical detection using GPR and electromagnetic locators
Each utility is assigned a Quality Level (QL) from QL-D to QL-A, indicating confidence and detection method.
Our Technologies
- Ground Penetrating Radar (GPR)
- Electromagnetic Locators (EML)
- GPS and GNSS positioning
- Sonde tracing and CCTV inspection
- CAD, GIS and BIM-ready deliverables
Deliverables
- Colour-coded utility maps (CAD/PDF)
- Depth and alignment data
- Quality Level classification
- Integrated topographical overlays
- Utility conflict drawings for design coordination
- GIS and BIM formats available on request

Frequently Asked Questions
What is utility mapping?
Utility mapping is the process of locating and recording underground services to support safe excavation, design and construction. It includes detection, verification and documentation of buried assets.
What is PAS128 and why does it matter?
PAS128 is the British standard for underground utility detection. It ensures surveys are delivered to a consistent methodology with defined confidence levels—reducing risk and improving safety.
Can you integrate utility data with topographical surveys?
Absolutely. We overlay utility mapping with topographical data to support planning, design and permitting.
Can you detect non-metallic utilities?
Yes—our GPR systems can detect plastic, clay and concrete services, though depth and resolution depend on ground conditions and object size.
