And you thought bunkers were so 1950s. Au contraire:

Constructed of 6500 PSI high tensile reinforced concrete and a proprietary blend of composite fibers and enhancers, the patented aerodynamic “DSS” boasts 12-inch thick steel reinforced walls that provide ample protection from normally unsurvivable forces including category 5 hurricane winds, flying debris, blizzards, fires, earthquakes and other all-too-common threats.
