Steel Bunkers

The Modular Steel Bunker is a proprietary line of bunkers from Atlas Survival Shelters that are specifically engineered to be buried. To achieve industry-leading quality, our bunkers are:

pressure-tested to ensure a gas- and water-tight seal to combat leaks from groundwater
coated with a cold-tar substance that is used to coat cargo ships, further waterproofing the material
engineered to be structurally sound under the massive weight of earth that covers them
