If you have the space and resources, you can turn a shipping container into an amazingly effective underground shelter. This is a great step-by-step example of how a 20 foot container can be buried, reinforced, and have utilities added to make a shelter that has everything you’d need in an emergency, and double as a cellar for food storage – or in this case, wine. 🙂
I-beams are placed on each side of the steps level with the container, then heavy sheet metal is placed over the top and across to each of the side banks. Blocks are set to create the entrance down into the container. Air vents are installed, along with PVC stubs for utilities, then a rebar framework is built over the whole unit.
The steps taken to build this shelter by installing the concrete cap and keeping water and dirt away from the walls will ensure it will stay relatively rust-free and last for many years. See the building process in the video below.
