Our shelters offer the "Faraday Effect." They are safe in lightning.
A "Faraday" is any enclosed "hollow" shell made of an electrical conducting material. If there is a large electric field outside the conducting shell, the electric charges on the shell will move around and rearrange themselves until the electric field inside the shell is zero. Therefore a Faraday structure acts as a shield for large electric fields or for electromagnetic waves. Including  Lightning and EMP's!

First we test them for leaks three ways: Visual, Zyglow, and water pressure at 4,200 PSI. 
We then coat them with a Marine epoxy,  five gallons or more of depending on shelter size.  It's even approved by the U.S. Corps of Engineers on dam gates. It's also used on  underground gasoline tanks, barges, and offshore drilling rigs.

Please don't just ask for more info! 

Unlike most, We show prices, sizes, pictures, and even videos. Look over the site well. 

Most questions are answered on our website.  Specific questions please. Thanks!

About Us.

Cozy Caverns is a BBB Accredited Storm Shelter in Austin, AR

Most of us have had the old "can't crack the egg" trick played on them. That and the fact most underground structures are in a rounded shape is the reason we designed our shelters with the dome roof. It's stronger. Same as tunnels, culverts, gasoline storage tanks and such are built. We've even run our backhoe across the top of ours; not even a dent!

Handcrafted quality, Built one at a time. We don't hire extra help during the rush season. That can compromise  the product. But, the end result will be worth the wait. Over 900 satisfied customers in 26 States, Since 1999. We must be doing something right.

A shelter isn't a shelter just like a crop duster and a Boeing 767 aren't both just airplanes.

Why Steel? Ground shifts. Steel can give without cracking like fiberglass or concrete. Look at your driveway.
We've had many people wanting us to dig up their concrete shelter and replace it with ours. Also, unlike most concrete or fiberglass, our stairwell is offset and doesn't take up room in your shelter. It's just a new Higher Tech and better approach to a creating a higher level of  quality for  protection against tornadoes. Bottom line... You can get cheaper, But, you won't get better for the price. We have folks all over the US come get one of ours. From South Florida, South Texas, to Montana, to Washington.

     
       There's a reason for it. Quality, reputation, and price.
