Concrete Shelters and EMP Protection

Concrete walls do not give EMP protection. If EMP protection is needed, rooms within the concrete bunker can be lined with metal, to form a faraday cage. Penetrations into these rooms will require EMP filters and wave guides, depending on the use and equipment within.

Rooms within concrete shelters can be lined with metal, to form a faraday cage. Theses rooms may also require large EMP filters and wave guides, depending on the equipment within. This can become a very expensive undertaking. Steel shelters make a natural faraday cage and will protect all electrical equipment inside the shelter IF there are no antennas or other electrical wires entering the structure. Every incoming wire potentially offers entrance of the electro magnetic pulse (EMP). All doors must have the proper gasket material, in order to protect against the slot antenna effect.
