Reinforcement of Facilities and Internal Spaces Against Blast Effects
Engineering Solutions for Retrofitting and Upgrading Protective Spaces The protection of existing buildings and internal spaces against blast effects is an important engineering challenge, particularly where complete reconstruction is not practical. Atmas Group provides reinforcement systems designed for both retrofit projects and new construction, with the objective of upgrading the protection level of rooms and structures against blast, ballistic and forced-entry threats. A
Rebound and Negative Pressure: What Happens to a Blast Door After the Initial Impact?
Explore how outward-opening shelter blast doors respond to initial pressure, rebound, and negative-phase loading, and why door construction, support conditions, and the basis of specified reverse loads matter.
Prefabricated Concrete Shelters and Bunkers: Modular Protective Structures
Prefabricated concrete shelters and bunkers provide a modular approach to creating protected spaces using pre-designed concrete precast modules and components. Atmas Group presents these solutions for both on-the-ground and underground applications, with configurations ranging from compact shelters to larger protective structures. Atmas Group The use of prefabricated elements allows protective structures to be developed according to the required application, capacity and pro
CBRN Filtration and Protective Shelter Technologies: Engineering, Equipment and Practical Demonstration
Modern civil defence shelters require an integrated approach to protection. In addition to the physical structure, protected facilities may incorporate CBRN air filtration, emergency ventilation, blast and overpressure valves, gas-tight components and other air-management systems. Atmas Group provides technologies and solutions for civil defence shelters, bunkers, safe rooms and other protected facilities, including CBRN filtration and ventilation systems, blast valves, overp
NordFort™ Modular Reinforced Concrete Shelters for Civil Defence: A Scalable Prefabricated Solution for Above-Ground and Underground Protection
Modern civil defence infrastructure requires shelter systems that combine structural strength, rapid deployment, modular scalability and compatibility with advanced protective technologies. NordFort™ Modular Reinforced Concrete Shelters, developed by Consolis in cooperation with Atmas Group, represent a complete modular shelter solution based on prefabricated reinforced concrete elements designed for both above-ground and underground installation.

The "Good Bunker" Composite Watertight Bunker System: Modular Polypropylene Formwork for Reinforced Underground Shelters
Modern civil defence infrastructure requires shelter systems that combine structural strength, long-term durability and efficient construction methods. The Good Bunker is a modular underground shelter solution developed around prefabricated polypropylene modules that serve as the permanent watertight shell and formwork for reinforced concrete protective structures. According to the manufacturer, the system is designed for underground bunkers covered with concrete and/or earth
CBRN Filtration, Ventilation and Air Management in Civil Defence Shelters
Modern civil defence shelters require more than structural protection. A protected facility also needs engineered systems for ventilation, air filtration, pressure control and the management of potentially contaminated air. Atmas Group provides solutions covering these areas, including CBRN/NBC filtration systems, ventilation equipment, blast valves, overpressure valves and CO₂/CO filtration systems. Atmas Group — CBRN / NBC Filtration Systems CBRN filtration CBRN refers to C
Build a Finnish S-1 Shelter Locally Under Our Design & Certificate: Localized Civil Defence Shelter Manufacturing Based on the Finnish Model
