Intrusive UXO Survey

intrusive uxo survey

1st Line Defence can provide Unexploded Bomb (UXB) Intrusive Survey to provide clearance ahead of individual pile locations, clusters & boreholes. This method permits survey at depths not achievable by non-intrusive methods and in conditions beyond of the detection capabilities of a non-intrusive magnetometer survey, such as in areas of made ground and gross ferro-contamination.

Anomalies identified during the survey, which are identified as having similar characteristics of a UXB, can be avoided or investigated dependent upon the site conditions and the client’s requirements.

The UXB Intrusive Magnetometer Survey can be deployed on different platform configurations to suit specific environments that our clients require including wheeled, tracked, railway compatible, confined spaces and over-water.

1st Line Defence can also provide a combined UXB and Cone Penetration Testing (CPT) Survey which will provide geotechnical data and clearance for UXB’s on each position surveyed.
