Core offering

Brimstone UXO provides a full suite of unexploded ordnance (UXO) risk mitigation services for construction, defence, government and energy clients across the UK and internationally. Its portfolio covers preliminary and detailed UXO risk assessments, intrusive and non-intrusive surveys (using CPT rigs, pushcart magnetometry and UAV-mounted magnetometry with LiDAR and photogrammetry), on-site investigation (watching briefs, borehole support, search and clear), and licensed explosive ordnance disposal. Services are delivered by long-tenured engineers using proprietary geophysics software for anomaly classification, with complementary IMAS-accredited training programmes and the live UXO intelligence platform Remnant.

Product overview

Brimstone UXO delivers a comprehensive suite of unexploded ordnance (UXO) risk management services spanning the full project lifecycle from initial assessment through to final disposal. The service portfolio centres on four core offerings: UXO Risk Assessments (preliminary and detailed desktop studies), UXO Surveys (both intrusive via CPT rigs and non-intrusive via magnetometry), On-Site Investigation (watching briefs, borehole support, and search and clear operations), and Licensed Explosive Ordnance Disposal. These are complemented by specialized capabilities including Drone/UAV Surveys (the UK's first commercial UAV UXO survey service with magnetometry, LiDAR, and photogrammetry), Marine UXO Services, and Deep Learning for geophysical data analysis. Training services include IMAS-accredited field courses and the UK's first online UXO Awareness Course. In June 2026, Brimstone launched Remnant, a live UXO intelligence platform providing real-time incident monitoring and visualization. Services are delivered internationally across sectors including construction, defence, energy, marine, and humanitarian, with a reported track record of over 223,750 UXO items found and 850+ client organisations served since founding in 2016.

Brands

• Remnant: A live UXO intelligence platform that monitors incidents as they're reported and visualises them on a single, continuously updated platform. Launched in June 2026.

Products and services

• UXO Risk Assessments Research-led desktop studies providing thorough preliminary and detailed UXO risk assessments drawing on historical records, site-specific data, aerial photography from wartime and post-war periods, and primary/secondary sources to identify UXO contamination risk. Sold to construction clients, developers, defence estates and energy developers ahead of ground-intrusive works.
• Intrusive UXO Survey Deep penetrating survey using CPT (Cone Penetration Test) rigs with magnetometer probes pushed into the ground by hydraulic pressure to detect UXO hidden deep below the surface, capable of approximately 20 probes per day and suitable for brownfield sites or sites with made ground. Designed for construction, energy and brownfield development clients.
• Non-Intrusive UXO Survey Surface-level survey using magnetometer sensors to detect shallow-buried ferrous anomalies without ground disturbance, conducted via five-channel pushcart, towed array or drone deployment. Five-channel magnetometry setup is used on greenfield land, with UAV surveys covering up to five times more ground per day than pushcart methods.
• UXO Watching Brief On-site monitoring service in which a qualified UXO engineer continuously observes ground intrusion activities to safeguard construction and development projects from unexpected UXO encounters during piling, excavation or drilling.
• UXO Borehole Support Service using down-hole probes to clear borehole positions as they progressively deepen, supporting cable-percussive, rotary, window and windowless sampling methods used by geotechnical and environmental contractors.
• UXO Search and Clear On-site service using advanced search equipment and techniques to quickly mark, excavate, identify and dispose of UXO targets in real time, supporting safe project progression on contaminated land.
• Licensed Explosive Ordnance Disposal Licensed explosive ordnance disposal services delivered globally by Brimstone's expert teams, including on-site demolitions and safe disposal of discovered UXO items at locations across the UK and internationally.
• Drone/UAV UXO Surveys UAV-mounted UXO surveys using magnetometry, LiDAR and photogrammetry technology to enable rapid coverage of large, difficult-to-access, or environmentally sensitive sites. Brimstone was the first company in the UK and internationally to bring drone-based UXO surveys to market, capable of covering up to five times more ground in a single day than pushcart surveys.
• Marine UXO Services Specialist UXO services for marine and coastal environments including underwater detection and assessment of UXO in dock, harbour and coastal areas, supporting port redevelopment and coastal construction projects.
• IMAS-Accredited UXO Training IMAS-accredited training courses including field-based Level 1 and Level 2 courses designed to build UXO awareness and technical skills for client personnel and partner-nation military staff, including training of in-country military in Lithuania.
• Online UXO Awareness Course CPD-certified online UXO awareness course providing in-depth UXO risk education. The first online UXO awareness course in the UK, approved by the International Institute of Risk & Safety Management and certified by The CPD Certification Service, aimed at construction, defence and infrastructure professionals who need foundational UXO awareness.
• Remnant Live UXO Intelligence Platform Live UXO intelligence platform launched in June 2026 that monitors UXO incidents as they are reported and visualises them on a single continuously updated platform, providing real-time situational awareness for construction, defence, energy and humanitarian users.
