Building a bunker could be a great option, since there are at least a dozen SHTF scenarios where you can save your life by having an underground bunker to hide and spend some time. Therefore, the idea of ​​making a bunker is excellent for all survival enthusiasts. A definite need for every experienced survivor. You will come to know that building a bunker is not as easy as it might seem, but once everything is ready and everything is finished, you will be at peace knowing that whatever happens, you and your family will be safe.

In order to help you get started and get an idea of ​​what you need to build your own shelter, we guide you with our step-by-step instructions on how to build a bunker.

How to start?

Regardless of what you are building, you need a permit; That means that the entire construction process must be legally permitted and in accordance with the law of your state. Otherwise, you may be facing unwelcome legal regulations and lawsuits, and that’s the last thing you need. Before starting to build your bunker, there are many things you must take care of.

One of those things is to make sure that you are legally authorized to dig a big hole in your backyard; There may be gas or water pipes buried in your backyard, and that is also the reason why you need to check everything legally. Once you have set this up and you are allowed to dig the hole, you can start digging.

Make a plan

No matter what you are plotting, as a survivor, you know that first you need to make a plan (things are not different in the construction of a bunker), it is the opposite, since you will have to work every detail before starting. excavation. There are numerous factors to consider: you must determine what type of soil you have in your yard or find out if you will need to dig through the concrete to build an underground bunker.

Some houses have concrete foundations that are deeply excavated in the ground, so making a bunker in that case would require much more work and planning.

When you consider all the factors, including mold, soil type, ventilation, radiation, and natural gas pockets that may or may not exist in your backyard, you can determine if you want to build a bunker under your home, or You can consider building a hut under which you will build an underground bunker.

The option of having your bunker built in another place instead of building it under your house has some advantages, since you will not have to worry about breaking the concrete or crossing gas installations or accidentally tripping over electrical installations, which can be very dangerous. Another thing to consider before starting is the climatic conditions in your country, especially the cold intervals, since it could happen that the soil collides in your bunker if your plan is not completely worked out.

If you are not an expert in the planning of construction projects, you might even consider hiring someone to help you with the planning, make a plan for your electrical installation network, as well as determine if building a bunker under your home is a problem. . smart idea

Advantages of having a bunker built under your home.

So, you’ve heard about some disadvantages of building an underground bunker under your house, but what are the advantages? There are many, in fact. If it is determined that building a bunker under your house is perfectly safe and feasible, then you will have less trouble providing electrical power to your bunker, and the fact is that you will need electricity. However, you can always turn to portable generators designed for home use and choose one that runs on batteries or fuel. That way, you will not have to worry about not having electrical power in your bunker.

So, even if you do not build the bunker right under your house, you could still have sources of electrical energy. But what about the entrance? You’re not spending much time in the hut, right? Therefore, building a bunker under a hut could be useless unless you decide to build a tunnel from your home to the underground bunker, which requires more planning and more work, although it is a pretty good idea and an interesting project.

The best thing is that you can easily access the entrance to your bunker, so, in case you can not leave your house to enter the bunker safely, you can access your bunker through your home; Preferably through your basement. Another question that might not go in favor of having the only entrance to your bunker through your house is: what happens if the house crashes?

Well, that would not be as good for you as you would be stuck in the bunker. To avoid this potential scenario, you should consider building another security entrance, covering it with curious eyes.


Then, if you are legally established and familiar with all the requirements of the area, in addition to having all the information about the groundwater, the gas bags, the type of soil and the climatic conditions, you can start digging.

To accelerate the process, it is recommended that you use machinery, and when we say “machinery”, we refer to heavy machinery – hard core style. Or, you might end up digging more time than you could want.

As you dig, you should know that the soil is well compacted, so naturally, the more you dig, the more soil will come out of the hole. Keep the soil away from the hole and save it for later, as you will surely need it. According to the size you want your bunker to have, it will dig the hole to match your plan and its construction, and once you have finished digging, you can continue with the construction of a structure for your bunker.

If you do not have the necessary machines to help you dig, you can always go to the old school and use a shovel. There is another option: rent the necessary equipment, since you can rent machinery or hire someone with the right machinery to help you.


The structure can be built by your own hands, but if you want to speed up the process and if you plan to build a smaller bunker, you can buy a large shipping box to meet the needs. You must make sure that the hole you dug is big enough to fit the cage and that it is not too big so that the ground does not collide. You can also request a construction as a mounting object and then simply place it in the hole, again making sure that the hole is aligned and is suitable for the structure to fit.

Once again, you will need a heavy machinery to place the box or its structure in the hole, so you can rent the machinery again, as you will need it.

On the other hand, you can build the structure by yourself and, in that case, you will not need to buy a box or ask for the object to be assembled, which also means that you will save some money in renting the machinery as you get moving. I will not need it

If you are going to build the structure by yourself, but that would mean you will have to do more planning, since the material used to build a bunker is very important. For everything to be fixed, you must first learn some basics about how to build an underground bunker when it comes to the material used to make the structure for yourself.

To begin with, although the wooden structure is a true classic to choose from to build its structure, you must know that the wood will decompose if it is not treated previously. There are also other disadvantages with regard to wood as a material for its structure: even if the wood is treated permanently, the wood construction is not suitable for an underground construction, since the toxins are released gradually into the soil, and that It is anything but Good for the construction of the bunker.

The wood is also not strong enough to support an underground building and is not as durable as concrete.

Speaking of concrete, this material is perhaps the best option for its structure, as it is profitable, durable and strong enough to support an underground construction. Basically, you will get everything you need when selecting concrete for your bunker structure material. After choosing the material, you must first start from the construction of the base of the floor and then move on to the fabrication of the walls for your underground bunker.


The construction of passages from your home to the bunker can also be useful, since you will have an alternative way of accessing the bunker when you need it. To ensure that passages are completely safe, you must secure them and to do so, you must choose the correct structure for your tickets.

A strong option to support the passages is to use the scaffolding posts that will give the small-sized rooms sufficient support, but avoid these poles being used to support the roof, as they are not as safe to support larger rooms, so there is a possibility that the roof could collide in that case.

If you are not sure which construction would be so good to hold the roof, you can feel safe using brick pillars. Brick wood could also be used as a large structure for the bunker, as it is much better than wood, but concrete is probably the main material for such projects.


Beware of obstacles, such as ground water, gas pockets, electrical circuits and, of course, rocks. There are many huge rock blocks under the ground and you must ensure that none of these factors can interfere with the construction of your underground bunker. .

If you run into groundwater, the best thing you can do is try to find another place to dig, since there is nothing you can do to make the water disappear. The positive is that if you have found the source of groundwater, you can take advantage of it and make it your main source of SHTF water supply, of course, you must build a required system for the water supply, but if it is potable and ecologically correct, the Groundwater is your treasure of SHTF.

However, if you encounter a massive rock, you will have to find another place to dig or go to work and start drilling the block. That, of course, will require more effort, more time, more money, energy and, once again, you will have to rent heavy machinery to get rid of the block.

Another thing you can do to make sure that the rock does not get in the way of your bunker is to build another structure around the massive rock and widen the hole so that your originally planned structure can fit, so that you can continue with the construction of your bunker.

If that option seems like a lot of work, you can pour some water into the cracks in the rock and wait for the water to freeze; the block will break easily afterwards. This will only work at low temperatures, so it could not be an option for you either.

Once again, you will have to plan every detail so that it does not end up with twice as much effort as originally planned.


One of your enemies when it comes to protecting the bunker is bad weather. The rain is good for the crops and the soil, yes, but it does not adapt so well to your bunker. At least if the bunker is not secured to be waterproof.

To make sure that the water does not reach your bunker, you can use some type of waterproof sheet, which can be easily placed on the roof of your bunker and protected from the water.

Thinking in different scenarios of SHTF, the need arises to think about the soundproofing of your bunker. There are many potential scenarios in which you would not want your bunker discovered because you were not whispering all the time you spent underground. Also, you probably want to keep your bunker a secret, so that’s where the entrance is hidden.

If your bunker is not built inside your house or in the basement, or if you have given up building a small hut on top of the bunker entrance, which is a pretty good way to hide your SHTF hideaway, it is recommended that you find another way to hide the entrance to your underground bunker. To begin with, the bunker should not be built in the middle of the opening, but should be covered with bushes or trees. One option is to plant trees and shrubs throughout the garden, including where the entrance to the bunker is located.

Survival features

You can not survive without water, so another thing to consider along with building a bunker is to build your own water supply system. If you were lucky enough to find the ground water, you can use that and build a water supply system that leads to your bunker for safe and easy access once the SHTF scenario occurs. You can also use rainwater and install the rainwater barrel system that will collect the rainwater for later use. Having water purifiers and living straw is an excellent backup option to have around the bunker.

Keep in mind that you will also need to plan your food supplies and find a way to bring electricity to your bunker if you think you need it (and you certainly do). It is recommended to hire an electrician for all work related to electricity, just to be sure.

Ventilation is another important aspect to have a fully functional bunker on long runs, so research and find the most suitable ventilation system that meets all your needs, so that your underground bunker can work perfectly once the SHTF scenario occurs.

To make sure that our instructions are visually compatible, here are some videos that will help you get a broader picture of how to build an underground bunker. You can have a clear overview of how the construction of a bunker should be:

Before starting to build a bunker, make sure that all the safety rules are well thought out and that your plan will work perfectly, since your survival could depend on how you build your underground bunker. As a survivor, you will surely know how important preparation is, so get ready, get ready and start digging!
