Clearance of unexploded bombs

Unexploded bombs are detected by performing surface or subsurface surveys, depending on the site conditions.

Once a suspected bomb has been localised, it is uncovered manually, with the aid of construction machinery. This process may also require deployment of special civil engineering methods, such as the vibration-free installation of sheet-pile walls, insertion of shaft rings or aluminium rings, or lowering the ground water level

All procedures must comply with the provisions of the BGI 833 safety guidelines.
