A safe room is a hardened structure specifically designed to meet the Federal Emergency Management Agency (FEMA) criteria and provide near-absolute protection in extreme weather events, including tornadoes and hurricanes.

Near-absolute protection means that, based on our current knowledge of tornadoes and hurricanes, the occupants of a safe room built in accordance with FEMA guidance will have a very high probability of being protected from injury or death.

Our flush exterior storm shelters are designed to be installed on flat ground and are completely underground, other than the top of the door and the air vent. Meaning our shelters do not protrude out of the ground.
