To keep a more natural aesthetic, and to provide optimum levels of comfort, our underground shelters are dome-shaped, making them substantially stronger than traditional metal box shelters. The modular shell panels are made with prefabricated aerospace composites nested in an outer core created with aerated concrete reinforced with synthetic fibers and waterproofed using Crystalline technology.
Our modular system can be used to create many different sizes and configurations. Because of its unique shape, it creates a naturally cool space, is easy to install, can fit in various depths, and provide security for years to come. With an eco-friendly underground shelter, you can create your own subterranean cave and safeguard your family against all of the elements.
For added peace of mind, we offer several extra options. This includes a nuclear, biological, and chemical (NBC) air filtration system with a hand crank for emergencies, CO2 scrubbers to remove carbon dioxide from the shelter whenever air pipes are blocked or if the air system is turned off, and a watertight hatch to keep your environment secure.
