Project Echt.jpg

Den Ouden Infra

Do you have constructions planned in non- post-war disturbed soil, or do you suspect that World War II explosive remnants (OO) may still be present in the soil?

Historical Preliminary Research & Risk Analysis

Den Ouden Bodac has years of experience in surface and depth detection and is a reliable partner when it comes to explosives detection and securing.

Explosives detection on land 

For the detection and clearance of non-explosive remnants of war in an underwater environment, Den Ouden Bodac has a team of specialists who perform the work with great care. 

Explosives detection in water 

Den Ouden Bodac investigates whether there are archaeological remains in the ground at the project site and then secures these archaeological finds.
