Gap Explosive Ordnance Disposal (Gap EOD) has unveiled UltraTEM, a technology designed to detect unexploded bombs underneath construction sites.

The system is based on equipment originally designed to locate leftover munitions following the First and Second World Wars.

Gap EOD spent more than seven years developing UltraTEM, which can identify unexploded ordnance (UXO) buried at depths of up to 3.5m below surface level.

Dr Stephen Billings, director of the Australia-headquartered company, said: “Gap EOD is now one of the only companies in the world with technology capable of finding bombs to the depths required to make areas safe for industrial, commercial, and residential development.

“We can scan up to 3.5m in depth using our UltraTEM system, which uses sensors to detect buried material. It’s a faster, deeper technique that completely redefines traditional exploration and tracing methods. It’s taken us over seven years to develop and refine the equipment,” he added.

UXO represent a threat to developers and contractors working in former conflict zones. Underground construction activities, such as the laying of pipelines, cables, or foundation works, can disturb and potentially detonate unexploded devices.

More than 83 countries, in regions such as the Middle East, Europe, North America, and Australasia, possess contaminated ground, according to Gap EOD.
