Shelter Features

We pride ourselves on the quality of our products. Our shelters are built with the highest quality materials including corrugated pipe and bullet-resistant hardened steel. Once you have selected the plot of land on that you would like to have your shelter installed, our team will begin designing and manufacturing your shelter based on what you need.

Build Quality

Shelters, Doors, Hatch, Air Filtration



We put 12″ of 4,000 PSI concrete underneath our modular shelters for ballast and to keep the shelter level from earth movement.

Reinforced with Concrete

We cover the square shelters in 12″ of 4,000 PSI concrete. This is needed to strengthen the roof and to create ballast.

Shelter Finishes

Wood Surfaces

Our stairs are hot-dipped galvanized and we use pressure-treated wood for the steps so they never mold or rot.

Galvanized steel

We use 6″ diameter galvanized steel for our air intake pipes. Our system brings in 50% more air.

All our air pipes are hot-dipped galvanized to prevent rust. The lifespan should be 100 years.

90-degree turn

Any shelter that does not have an L-shaped or 90-degree turn at the bottom of the stairs is going to let in the prompt radiation at the time of the blast because the radiation will go right through metal as if it wasn’t there. What is protecting you is the 36+ inches of earth on top of you, not the door.

This image shows a properly engineered entrance into a nuclear fallout shelter. It must have a 90 degree turn at the bottom of the stairs.

Why do I need an L-shaped entry into my shelter?

A 90-degree turn at the bottom of the staircase is vital to the survival of the people inside. The 90-degree turn will attenuate the gamma radiation so that it does not enter the shelter. Any shelter that does not have an L-shaped or 90-degree turn at the bottom of the stairs is going to let in the prompt radiation at the time of the blast because the radiation will go right through metal as if it wasn’t there. What is protecting you is the 36+ inches of earth on top of you, not the door.

Protective Paint

Atlas tries to hot-dip galvanize as many items as we can. Those items that are not galvanized are sandblasted first, primed with an automotive primer, and painted with automotive paint. Yes, the same paint as on your car.

Atlas Shelters Guaranteed Quality

Our owner is an award-winning designer and fabricator with 37 years of experience.



Our hatches are designed after the nuclear blast hatch by the US Nuclear Civil Defense Department. It is surrounded by heavy 12″ channel, then surrounded with 12″ of concrete.

Rust Protection

to prevent our doors from rusting Anything that we do not hot-dip galvanize we will at least sandblast and apply either an automotive type of paint on the interior and the hatches

High-Quality steel

Our doors and hatches are AR500 bullet proof steel


Our hatch opening is 36×80 inches and the stairs are at a 35-degree angle which makes it easier for the handicapped and elderly to get down the stairs.

Hydraulic Lifts

Our hatch is hydraulically lifted due to the extreme weight of the hatch. Another example of a style of hatch we use are spring



Marine-grade doors are used for the entrance below in the living quarter’s area for decontamination. Our doors are both gas-tight and waterproof. If the shelter is not airtight, biological, chemical, and some radiation will get into the shelter

Locking System

there is a 6-point locking system hidden inside the bunker. the door also Features an interior door latch

Air Filtration System

Business Partners

we get our NBC Air Filtration Systems from companies like Andair and Bethel who are professionals that have been doing this for over 50 years

Air Circulation

the air system brings in 50% more air than systems with 4-inch air pipes.


All Atlas air systems are made from metal housings and have readable gauges and adjustments for airflow. We use 60 pounds of carbon.

Ease of use

Every NBC Air System we provide has an easy manual crank in case you lose power. Our NBC Air Filtration System is so easy a 6-year-old girl with one arm can operate our air systems as shown in our pictures.

How Does it Work??

Atlas Survival Shelters uses only military grade NBC Air Filtration Systems from companies like AndAir or Bethel who produce thousands per year.


Entrance, Blast Valves, Air-pipes, Escape Hatch, Concealment


Water and Gas-tight Doors

The exterior hatch is bulletproof and the interior doors leading to the living area are water and gas-tight to prevent unwanted stuff from your bunkers

Steel Box

The Atlas hatch has a tamper-proof steel box to protect the tamper-proof padlock from torches or grinders.

Mud and Decontamination Rooms

Any properly designed and engineered nuclear fallout shelter will always have a shower present before you enter the shelter. If you enter a shelter covered in fallout, you will not only contaminate the shelter, but you will endanger other people.


This is our 8×12 from our website. Notice the decontamination shower in the mudroom, the 90 degree turn at the bottom of the stairs, the larger entrance hatch, and the interior doors that open out.


The mud room – or decontamination room – has a shower in it as specified by the nuclear guide handbook.

Blast Valves

Emergency Protection in Air Pressure Changes

A nuclear weapon creates a shock wave, which may produce sudden pressure changes of more than an atmosphere (about 1 bar) even several kilometers from the detonation point. After the shock wave passes, a sudden negative pressure follows.

the Atlas overpressure blast valve can be manually pulled closed in case of an attack from looters

Air Pipes

Tamper-Proofed Airpipes

Our system not only protects you from vandals, but it also cools the air down before it enters into the shelter through our patented air condensation system. Also, our air pipes are 6″ in diameter compared to 4″ in diameter on the Nado series.

Escape Hatch

Basic Features

The escape tunnel is standard on all the larger Atlas Shelter models. It is not included on the Nado Series and some of the smaller Atlas shelters. The way the escape works: You crawl through a 42-inch pipe and then you climb up a ladder that’s installed into the escape tunnel. The escape box is full of sand that must be released before you open the door down into the escape tunnel. Once you get to the top of the escape box, you will have to punch through about 12 inches of earth to get to the surface.

In Case of an Emergency

In the case an intruder tries to enter your bunker through the main hatch, you have the means to escape by digging out through the ATLAS ESCAPE HATCH and escape or defend your shelter.


Avoiding Detection

A good way to avoid unnecessary attention from looters or intruders is to make your entrances and escape hatches hidden

Storage Facility

Under the Floor Storage, Storage Locations, Water Storage, Vaults

Under the Floor Storage

Our shelters are famous for under-the-floor storage.

The advantage of having under-the-floor storage in your shelter is that it gives an incredible amount of storage which keeps all your supplies out of sight. Square shelters have no built-in under-the-floor storage, We do offer under-floor storage on our square shelters for an upcharge.

Storage Locations

These locations are under the floor, under the bed, under the TV, under the dinner table, and under the counter.

How long can I stay in the bunker?

You can stay in a bunker as long as you have food and water. All our shelters will hold enough food and water for a minimum of 30 days at the capacity listed. Our larger shelters with underfloor storage can hold up to 6 months of food and water, and some can even hold more.


Water Storage

Water Capacity

1250 gallon to 2500 gallon polyethylene water tanks can be pre-installed on your bunkers


Installing a Vault is also a great idea to store your guns and some important valuables

Electrical and Plumbing

Electrical System, Water System, Wirings and Fittings, Emergency Power

Electrical System

There are a few primary systems that people use. Solar with a battery bank in the bunker is popular and now there is an EMP-proof model on the market. The second is an underground diesel generator in a separate generator pod, but this is strictly for large shelters. The third is an above-ground propane stand-alone generator that can also be used as the backup to your house but any power source above ground is susceptible to vandalism and high winds.

Water System

water filtration systems can also be outfitted, for a clean drinking water supply

Wiring and Fittings

Electrical wire fittings and Plumbing are neatly organized and stored for easy access and repairs

Emergency Power and backups

Air System Manual Crank

Every NBC Air System we provide has an easy manual crank in case you lose power.


Emergency LED lights are activated in case of an emergency power outage
