HEWEX® PEM Bunker

Monolithic Structural Electromagnetic and Radiological Protection System

Some facilities demand considerably more than high Shielding Effectiveness. Critical infrastructure, defence installations, strategic command centres and specialised research environments require protection systems that combine exceptional electromagnetic performance with structural durability, long-term operational resilience and, where required, integrated radiological protection.

HEWEX® PEM BUNKER has been developed as the highest level of the HEWEX® engineering platform, enabling Structural Electromagnetic Shielding and Radiological Shielding to become an inherent part of monolithic reinforced-concrete structures.

Rather than adding protection to a building, HEWEX® PEM BUNKER engineers protection into the structure itself.

The result is a permanent protective envelope designed to support facilities where operational continuity, structural resilience and long-term reliability are fundamental engineering objectives.

For what investments?

HEWEX® PEM BUNKER is designed for investments with specific requirements for electromagnetic safety, structural durability, and operational resistance. This technology is applicable wherever the protection system should be an integral part of the building structure, ensuring long-term reliability and the possibility of simultaneous electromagnetic and radiological protection.

Why this level of protection?

HEWEX® PEM BUNKER was developed for facilities where electromagnetic shielding is one element of a comprehensive security system. The monolithic design of the technology allows for designing protection as a permanent element of the facility, ensuring high mechanical resistance, stable protective parameters, and the possibility of integration with radiation shields. By using a structural electromagnetic shielding system, it is possible to achieve very high protection effectiveness while maintaining EMC integrity and resistance to operational damage. The solution is individually designed for each investment, taking into account its function, threats, and required level of safety.

What does the investor gain?

  • a monolithic electromagnetic protection system integrated with the facility's structure,
  • simultaneous electromagnetic and radiological protection,
  • very high shielding efficiency over a wide frequency range,
  • very high mechanical resistance,
  • a homogeneous protective structure ensuring continuous shielding,
  • durability of protective parameters throughout the entire period of operation,
  • the ability to design facilities with increased safety requirements,
  • individually designed protection system adapted to the investment requirements.

How effective can you design?

HEWEX ® PEM BUNKER enables the design of systems achieving approximately 75–85 dB of shielding effectiveness at 100 MHz and over 105 dB from approximately 300 MHz , while maintaining very high protection effectiveness also in the higher frequency range.
Combined with its monolithic design and the possibility of integration with radiological shields, the technology is used in the most demanding infrastructure and special investments.

Where do we use it?

HEWEX® PEM BUNKER is designed, among others, for:

Critical infrastructure

Command centers

Military facilitiies

Shelters and protective facilities

Specialized laboratories

Security centers

Facilities requiring simultaneous electromagnetic and radiological protection

Strategic state and industrial investments

Why Choose HEWEX® PEM BUNKER Over Conventional Shielding Technologies?

Conventional electromagnetic shielding technologies based on conductive foils, metallic meshes and lightweight metallic enclosures continue to provide effective protection for many engineering applications. These solutions remain appropriate wherever shielding performance alone satisfies the operational requirements of the facility.

HEWEX® PEM BUNKER was engineered for projects where protection extends beyond electromagnetic shielding alone. It integrates Structural Electromagnetic Shielding, Radiological Shielding and the structural performance of reinforced concrete into a single monolithic engineering solution designed for mission-critical infrastructure.

Rather than attaching a shielding system to the building, HEWEX® PEM BUNKER makes the building itself an integral part of the protection strategy. This approach delivers exceptional mechanical durability, long-term stability of protective performance and permanent integration with the facility throughout its operational lifecycle.
