Uxo Borehole support

Our UXO Specialist's are equipped with the Sensys SBL10 Magnetometer to carry out  downhole uxo mitigation surveys to detect the presence of ferro-magnetic anomalies, which could represent the presence of buried unexploded bombs (UXB).

Our UXO Specialist's will attend site and carry out a surface scan of each borehole location, prior to exploratory works commencing. Once confident clearance has been issued onsite, the drillers will be cleared to continue 1m depth before another UXO magnetometer survey is carried out. Surveys will be carried out at 1m intervals from surface to the required depth.

Required depths are assessed on site by our UXO Specialist, who will combine magnetometer survey results with the geological data gathered by the on site Engineer/Driller to confirm maximum bomb penetration and safe continuation depths.

Once maximum bomb penetration depth has been reached, our UXO Specialist will give verbal clearance for the drillers to continue to the required depth of the borehole.

Our UXO Specialist's have years of experience working with window sample, cable percussion and rotary drillers across the UK, which has enabled our specialists to understand how drillers work and the processes required for each drilling method. This allows our UXO Specialist to know the optimum time to carry out each survey to help to reduce disruption to the progress of works. Each survey takes around 5 minutes to carry out.

If at any point our UXO Specialist detects an anomaly, the site supervisor/manager will be notified and the borehole will either be discontinued or moved to an alternative location. Our UXO Specialist will complete a report outlining why the borehole has been stopped, what depth was reached and what magnetometer readings are recorded. Further investigation works will be carried out if required.
