CBRN shelter

an internal sign of responsibility

To address CBRN threats

Keep your family safe.

In an increasingly uncertain world, the ability to protect people against modern risks — nuclear, radiological, chemical, and biological threats, as well as explosions — has become a critical requirement. Bünkl designs and delivers high-performance protective shelters engineered to withstand the most demanding scenarios. Our solutions combine CBRN filtration systems, controlled overpressure, blast resistance, and structural durability to ensure maximum safety for occupants.

The CBRN shelter

with an independently certified design

In many countries, having access to a bunker is a legal requirement. In France, what seemed extreme a few years ago is now a matter of common sense and responsibility in the face of rising CBRN (nuclear, radiological, biological, and chemical) risks and threats. Bünkl is the only company in France with independent certification for the design of civil protection shelters. We design your underground shelter based on your location, the layout of your home, and the specific needs of your family. We use high-quality components that are certified or recommended by civil defense authorities in leading countries in this field (Switzerland, Finland, Sweden, Israel… ).

Our certification

CBRN filtration

A vital component for air decontamination

CBRN filtration is much more than a simple particle filter. Made of highly microporous activated carbon with specialized impregnation, it offers a very broad filtration spectrum against toxic agents (viruses, radionuclides, acidic gases… ). It is this system that will protect you from inhaling toxic particles.

Blast doors

The first line of defense against shock waves

Blast-resistant doors are essential for maintaining the structural integrity and airtightness of the shelter. Our doors can withstand shock waves of up to 9 bars of pressure with and optional ballistic and thermal resistance.
