ExSpar Inc. was founded by two U.S. military veterans who design and build underground bunkers and saferooms that provide the best protection possible in the event of a natural or manmade disaster. Tapping into extensive experience in overseas combat and law enforcement as well as welding and fabrication, our team goes beyond designing and building your bunker, providing detailed guidance on set up, stocking, and use to help ensure your family’s survival.
