DEMINETEC, a French company headquartered in La Seyne-sur-Mer (Var), delivers civilian demining (pyrotechnic clearance) and unexploded ordnance (UXO) risk management services to public and private clients in Paris, France. We cover the full chain from historical pyrotechnic desk study (EHT) to ordnance neutralisation and disposal, in line with French Decree 2005-1325 and international best practice.
Paris has experienced three major waves of pyrotechnic risk: the Prussian siege of 1870-1871, German bombardments in 1914-1918 (the Pariser Kanone, zeppelin and Gotha raids) and above all the 1940-1944 occupation, marked by Allied bombing of peripheral factories (Renault Boulogne-Billancourt, La Chapelle, Gennevilliers) and by the August 1944 liberation.
The Paris region also hosts former ammunition manufacturing and storage sites (Sevran-Livry and Le Bouchet powder works, Issy and Vanves forts, Saint-Cyr depots) whose footprints are now the focus of vast urban projects, from Grand Paris Express to the 2024 Olympic Games.
Construction sites across Île-de-France (brownfield redevelopment, metro extensions, mixed-use districts) regularly uncover UXO, making historical desk studies (EHT) and magnetometric geophysical surveys indispensable before any deep earthworks.
Document research in national and foreign archives to qualify pyrotechnic risk on a site (bombings, combat, depots, ranges).
Residual risk assessment, definition of effect zones, safety perimeters and collective protective measures.
On-site detection of ferromagnetic anomalies, surface or deep, onshore or underwater.
Extraction, identification and neutralisation / disposal of munitions by our NEDEX / EOD-qualified operators.
Survey and clearance in ports, rivers and offshore environments, in partnership with our group company SEMTEC.
DEMINETEC operates in Paris and across France from our French head office (285 avenue Marcel Paul, 83500 La Seyne-sur-Mer, France). We mobilise teams and technical assets to fit each mission: documentary studies, short field surveys, or long-duration clearance operations.
In Paris and across France, the most frequently recovered items include artillery shells, hand grenades, landmines, aerial bombs and — in coastal areas — naval mines. Exact typology depends on the site history and is the focus of the prior historical desk study (EHT).
French Decree 2005-1325 governs civilian pyrotechnic clearance on French soil. Internationally, DEMINETEC uses it as a best-practice benchmark alongside IMAS (International Mine Action Standards) and the contractual requirements specific to France.
Duration varies with surface area, investigation depth and anomaly density. An EHT desk study takes 2-6 weeks, a magnetometric survey from a few days to several months, and active clearance from a few weeks up to multiple years for major projects.
Yes. Through our subsidiary SEMTEC and the DEMINETEC group, we provide commercial diving, underwater magnetometry and submerged-ordnance neutralisation for ports, rivers, lakes and coastal areas.
