Municipality of Aalburg 2011
For the new district ‘Den Eng' in Veen Bodac has conducted explosives research. In addition to surface detection, depth detection has also been carried out. With the aid of a cone with a magnetometer the soil can be searched for large metal objects up to a maximum of 18 meters below the surface. In areas with a ‘weak’ subsurface, (aircraft) bombs may have penetrated the soil to a greater depth. To find conventional explosives at such depths it is necessary to work with an MDE-drive. This is a long lance with a sensing probe in its tip, which is pressed into the soil in accordance with a predetermined measuring grid (as in probing). This implies that a (senior) OCE-expert is real time monitoring the penetration of the measuring probe into the ground. When a disturbance is measured the OCE-expert can immediately stop the process and register the measurement. This way a major area can be mapped relatively quickly and accurately. An advantage of this method is that the soil structure remains intact. During the excavation work remains of a 60 LB SAP missile were found. This resulted in an adjustment of the search order. As expected according to the historical research, remnants of an aircraft bomb were also found.
