Specialist UXO Detection Equipment Built for Precision and Depth
Cone Penetration Testing
S.I UXO operates a robust Cone Penetration Testing (CPT) rig dedicated to intrusive UXO surveys. Our tracked rig provides deep-penetration magnetic susceptibility readings capable of identifying large air-delivered ordnance up to 10 metres below ground level.
Key Features:
20-tonne static weight for enhanced soil penetration
Integrated magnetometer array and data acquisition
Operates in constrained and urban environments
Rapid deployment and low environmental impact
Unmatched stability on soft or variable ground
Whether validating pile positions or confirming deep anomalies identified in geophysical surveys, our Cone Penetration Testing rig offers reliable, repeatable results for high-risk locations.
Other Key Equipment:
Towed and handheld magnetometers
Digital multi-channel geophysical arrays
Borehole cameras and positioning systems
ATEX-rated detection tools for explosive environments
Tracked Vacuum Excavation
S.I UXO offers tracked vacuum excavation services to support safe, controlled investigation and clearance of buried utilities, anomalies or suspected UXO. Designed for use on soft, unstable or restricted-access ground, our tracked systems deliver high-precision excavation with minimal environmental impact.
Tracked vacuum excavation combines high-pressure air with a suction system to break up and remove soil without the need for mechanical digging. Unlike conventional excavation, this method reduces the risk of striking live services or disturbing sensitive subsurface hazards.
The tracked platform allows access to challenging terrains such as brownfield sites, embankments, waterlogged ground or confined urban locations.
Key Features:
Tracked chassis for low ground pressure and access to soft or uneven terrain
Non-mechanical excavation minimises the risk of UXO detonation or utility damage
Ideal for pile position investigation, target validation and service avoidance
Reduces reinstatement costs and environmental disruption compared to mechanical excavation
Can be deployed as part of a comprehensive UXO risk mitigation strategy or as a standalone service
This method enhances safety and efficiency across a range of high-risk and technically constrained sites. When integrated with S.I UXO’s intrusive survey and geospatial services, tracked vacuum excavation offers a complete, low-impact solution for sub-surface access and risk reduction.
Drone Survey (Walked Magnetometer Survey)
Our drone (or walked) magnetometer surveys are designed for use in areas where vehicular access is restricted or unsuitable for towed systems. This method is particularly useful on constrained sites, overgrown land, woodland, or areas with buried infrastructure.
Key Features:
Single or dual-sensor handheld magnetometers
High-resolution detection of localised ferrous anomalies
GNSS logging for positional accuracy
Minimal setup time, adaptable to complex terrain
Ideal for linear assets, access routes, small plots and infill zones
Drone surveys complement wider survey strategies and are often deployed to assess specific features or hard-to-reach areas identified during desk-based assessments.
Geospatial Services
Geospatial data underpins all effective UXO risk assessments, surveys and clearance operations. At S.I UXO, our in-house geospatial team manages spatial data capture, analysis, and reporting to ensure all outputs are accurate, usable, and aligned with client and regulatory requirements.
Key Features:
Georeferenced mapping of UXO risk zones and anomaly locations
GIS integration of survey data, historical archives and construction overlays
Custom basemaps for client use (AutoCAD, GIS, BIM formats)
Site layout planning for intrusive works, pile positioning and safe corridors
Production of high-resolution UXO risk heatmaps for planners and engineers
Our geospatial support ensures survey results are fully integrated into your project workflows, aiding design decisions, health and safety documentation, and long-term digital records.
S.I UXO is a UK-based leader in unexploded ordnance risk management, delivering compliant services for land and marine developments with precision, safety, and integrity.
