The Weakness Of Underground Bunkers

We often think of underground bunkers as being the ultimate survival backup plan. Whether it be a natural disaster, civil unrest, or the zombie apocalypse, these survival shelters can prove to be pretty useful when it comes time to batten down the hatches.

However, if they are not built properly, these bunkers can quickly throw a wrench into your survial plans. Along with stocking your bunker with everything it needs, you need to ensure the structural soundness of your shelter.

Read on to take a look at three of the most common weaknesses in underground bunkers.

Weak Entrance

Entrances are typically the weakest part of a structure. Debris from a major disaster could force the door inwards, in which case you are no longer protected from the elements and are exposed to broken remnants flying inside. You also need to be able to conceal yourself from unwanted visitors.

Your best option is to have a solid-core door, such as a mix of steel and plywood,. A steel frame is also an integral part of your entrance. You may have the world’s best storm shelter door, but a weak frame will make it useless.

You may also install a 90 degree barrier outside the door to inhibit intruders from knocking the down the door. Construct a concrete or cinder block barrier with just enough room to open the door and climb inside the shelter.

Check out if your door is FEMA approved.

No Air Circulation

Air circulation is critical. I once heard of a group of folks that hid in an underground school bus. Although this is an innovative idea, the bunker did not have adequate air circulation and the group of people baked to death.

While the ground around the walls offers protection from natural disasters and most explosions, it can also be an oven, trapping heat. You not only need proper air circulation to cycle in oxygen and maintain body temperature, but also to cycle out contaminants or contagions.

A simple remedy can occur with two holes and a fan, although HEPA filters can remove airborne bacteria and viruses. You can also use UV light to disinfect the air before it is circulated.

Waste Management

The time you plan on retreating into your bunker will vary depending on the situation, but you can never count on an exact estimate of time. That being said, sewage and garbage must be dealt with as to avoid harboring contagions and diseases within the underground shelter. Depending on the terrain, a septic tank or sewage system can do the trick. You may also incinerate garbage inside the shelter, as long as there is proper air circulation.

Now that you are aware of these weaknesses, we hope you are able to improve your next underground bunker.

  1. Folks- remember talking inside your shelter many times can be herd thru your air and return intake.
    if you plan on using abs or pvc be sure and use a T at your turn and a couple if foot of pipe going down in the ground to catch condensation that will collect in your pipes.
    Good Luck.

  2. The solar panel control advertised……..does it produce only 115 volts. Or can it provide 220 volts . I live in Mozambique on the east coast of Africa
    Many thanks

  3. well you do need to camo your entrance and vents due to unwanted intruders as well as the 10 to 12 feet of dirt to protect from fallout….however think of the time spent in this inviroment?….you need a good mental library or you will go “stir” crazy…so food .shelter.physical well being and mental well being.once you got this thing built see how long you can last in it ????

  4. The weakest point of any underground structure is the fresh air intake,all it takes is for someone to tie a plastic bag over the air intake and then wait for them to open the door.T he best way to avoid this problem is to keep everything concealed,The shelter and any type of ventilation must be hidden.

  5. One concern i have is the potential for intruders to breach the vents that provide air or circulation cabilities by introducing foreign substances such as smoke or water that would force an early evacuation.

  6. The entrance needs a 90 degree barrier minimum to prevent radiation from entering through a closed door. That barrier and the entire shelter should have 10 feet of earth minimum to protect against fallout.
