Even seventy years after the end of World War Two, war relics such as ammunition, small explosives and bomb duds are still being found at construction sites. As the property developer, you are obligated to organise your construction site in such a way that no dangers ensue as a result of work being performed. You are also faced with considerable economic disadvantages in the event of an unexpected discovery of wartime ordnance, such as a construction standstill, possible evacuations, or in the worst case, damage to people and property caused by explosions.
This is why a precautionary search for explosive ordnance forms such an important part of every ground investigation. Minimise your risks and protect the health of all those who may be in the vicinity of your construction zone.
Our trained personnel are available at any time to conduct a professional search of your construction site for potential contamination from ordnance materials.
Be on the safe side and trust in a historical-genetic reconstruction, the indispensible basis of any successful explosive ordnance detection.
We offer the following investigation services for explosive ordnance detection:
– Surface searching
– Depth sounding
– Explosive detection during building phase
One of the surface search methods we offer is of course the conventional technique of using a hand-held sensor to detect any foreign bodies in the soil surface. However for more extensive documentation, we highly recommend a computer-aided surface search, in which we investigate the potentially contaminated surface over a wide area. The area under examination is continually recorded and subsequently subjected to a graphical analysis. If the soil displays any ferromagnetic anomalies, we can pinpoint their coordinates immediately. Depending on the geological soil conditions, the depth that can be reached with surface searching can be up to three metres below the upper edge of the terrain.
Explosive detection during building phase
The process of depth sounding areas with potential explosive contamination takes the form of exploratory bores conducted in a grid formation. These are then lined with non-ferromagnetic pipes (PVC level pipe) prior to deploying the probes. The measurements are subsequently analysed by computer, which produces a graphical representation of the locations of any ferromagnetic anomalies detected. The process takes the form of depth sounding, also known as bore hole sounding, and is performed by our specialist personnel; this may be done, for example, during ground investigations, but it is also used for pile foundations, sheet pile walls and lining beams.
With qualified depth sounding, you know whether your suspected contaminated ground is in acceptable condition or whether clearing activities are required, even down to great depths. You can trust in the high standards of our trained specialists even when it comes to bore hole sounding.
