How to Build an Underground Bunker

Whether you are preparing for the end of the world as we know it, or you are curious as to what you should do in an emergency situation, you might be considering how to build an underground bunker.

There are a few ways of doing so in terms of materials, but there are some basic things that you will need in order to build your own underground bunker.

There are many threats today in the world that we live in, and the future is always unknown, but if you find yourself preparing for the worst, then we will let you know here how to build your very own underground bunker. 

The majority of people that build an underground bunker will do so in their own backyard. This typically makes sense, as if a disaster were to strike, then everyone that you live with will be ready and prepared. You can use this as an emergency meeting place just in case the worst does ever happen.

Getting Permission

Something that you might not think about is getting permission to build your own underground bunker. You can’t simply go ahead and start digging up your backyard or in a local area if you are not permitted to do so.

Make sure that you have the correct permission or permit to start the building process so that you don’t get into trouble. If you own the land, this might not apply to you, but it is always better to double-check just in case. 

What Do You Need in Your Shelter?

One of the first things that you will need to consider before building your shelter is what you actually require from it. The size of the shelter will depend on how many people there are going to be living inside of it.

You should also think about what you will need to protect yourself from, as this will determine the materials that you use while building it.

In terms of supplies, you need to think about how long you will be using your underground bunker, as you don’t want to run out of food and water before it is safe to leave. 

How to Build an Underground Bunker

The first step in building an underground bunker is planning. You will need to think about every possible problem that could occur before you even start building.

Try coming up with a sketch or plan of the layout, as this will help you be able to think about your plan of action. How are you going to filter the air? Where are you going to go to the bathroom?

These are all things that you are going to need to carefully consider before you even think about starting to build the structure.

Most importantly, it needs to be big enough to house you and your family, with enough room to store the essential items that you will need to live underground for as long as you think that you will need to.

Once you have your thorough plan in place, and you have considered every single possibility, you can start to actually build your underground bunker.

The most obvious thing that you will need to do first is to start digging. You need to dig deep enough to protect you from any situation and wide enough to fit all of you inside. 

You should use cement to create the foundation as this will stop the hole from collapsing, and it will also make the living area much more pleasant. You can then start to build your structure.

The most cost-effective option for the structure is to use cement and bricks, just as you would build a house. However, the most ideal is metal sheeting, though this is more expensive.

Metal sheeting is the most long-lasting material that is the least complicated to use. You shouldn’t use wood for the structure of your bunker because it will start to rot and break down over time, which is not ideal at all. 

When you have finally finished building the foundation of your underground bunker, you might want to think about hiding it from plain sight. Ultimately, the bunker is there to help keep you and your family safe, and you wouldn’t want somebody trying to steal your sanctuary from you in an emergency. 

Things to Consider When Building an Underground Bunker

Building the underground bunker itself is a difficult task, but there are also some other factors that you will need to consider while doing so.

It isn’t as simple as building a shelter underground, and there are other complications that you can run into if you aren’t careful.

Filtered Air

It is hard to know exactly how long you will be living in your underground bunker, and you are going to need access to fresh air if you intend to be there for a long period of time.

This is especially important if you are in a situation where the air is contaminated, like nuclear fallout. When you are building your bunker, make sure that you leave room for air vents to provide you with fresh air and help to keep the bunker cool in warmer weather.

Make sure to purchase an air filtration system and stock up on air filters. This will ensure that you are prepared for any emergency that requires you to live underground.

It is also a good idea to buy enough gas masks for you and your family just in case your air filters are compromised or you are forced to leave the bunker before the air is safe to breathe.

Give Yourself a Way Out

If you create the perfect underground bunker, and the entrance gets stuck with debris, you will be trapped. Without an alternative escape route, you will be creating your very own tomb.

In a situation where your only escape route becomes blocked, you will become trapped in your bunker. The only way to save yourself in this situation is to include an alternative escape route when you build your bunker.

It might be more difficult to have to monitor two entrances to your bunker, but it will be worth it if the worst happens. There is no point in having an underground bunker if you get trapped inside.
