What Is An Underground Bunker And Why?

With the popularity of underground bunkers growing due to the trend of prepping, it’s important to take a step back and examine the different types of bunkers and find out what’s best for you before you begin to invest in one type or another. Rather you are looking at bunkers for shelter from storms, fear of nuclear attack (which always seems to be looming according to this article from the Guardian) or martial law you need to make sure that whatever choice you make that it fits your needs. Consider factors such as storage space, number rooms, bunks and energy. You also need to consider your price range and rather you want an above ground, partially underground or underground bunker.

 There are pros and cons to each different type of bunkers that you should be aware of before you make any commitments. Here are some of those pros and cons:


Pros and Cons of Steel Bunkers

Steel is one of the strongest alloys out there, it’s not easily cracked or dented. A pro to consider when it comes to underground steel bunkers is that steel will contract and expand with the ground and it will not crack. The classic 4 wall shape is great because it allows for you to maximize your space within the bunker. However, the cylinder is a stronger shape than the cube. This is because a cylinder can absorb and distribute initial shock better than a cube. A cube will absorb all of a blow in the exact area that it was hit. This can lead to damage to the structure.

Pros and Cons of Pipe/Culvert Bunkers

Pipe or culvert bunkers are bunkers that are cylinder shaped and made of galvanized corrugated pipe. This cylinder shape is about 11 times more durable than a square, box shape. However, interior is usually wood which makes the whole bunker susceptible to fire. Also, these types of bunkers are welded, and on galvanized metals welding will accelerate rust. Space is also a major issue as the floor must be raised from the bottom to make room for walking and everything you put in must be rounded so that it can fit against a wall. If you're still not quite sure what a "culvert" pipe is then check out what Ask.com says about it.

Typically the price for a pipe bunker is usually cheaper than for a steel bunker which is a major plus, but the strength and room you get with a steel bunker might be worth the extra money.


Whichever type of bunker you decide is best for you make sure you research the company you use as well. Because prepping has become so popular you better believe that there are sharks out there just trying to cash in on the bunker industry without delivering what they promise. Also, carefully consider location and make sure that you have enough room for the size of bunker you decide on.

One of the best ways to take care of your family is to plan ahead for those unknown and unforeseen disasters that loom around the corner. Bunkers are one of the best ways to prepare so make sure you are educated on them so you can make the best choice for you and your family.
