underground storm shelters and tornado shelters provide protection for what matters most...your family.We design all of our Supercell Shelters™ in house. An Alabama Professional Engineer certifies and stamps each unit to meet and exceed the requirements set forth by FEMA 320, 361, and ICC 500 codes. Our underground storm shelters undergo testing at Texas Tech, Wind Science and Engineering Research Center. They pass all requirements to withstand the impacts of 250 MPH winds of an EF-5 tornado.


Supercell Shelters™ manufactures every underground tornado shelter in our own 37,000 sq. ft. facility  in Decatur, AL. We have a showroom open six days a week to allow customers to see our quality and design.

Supercell Shelter™ employees install every storm shelter, not a sub-contractor. Our mission is to help better prepare your family for the “next round” of hazardous tornadoes that frequent our area. We strive for perfection in everything we do. Our goal is to provide you with the best protection available at a reasonable price. You will not find a company with more dedication anywhere in the country. We design our solid steel underground storm cellars to install in garages and covered patios. We install our tornado shelters in both new and existing homes. These units can usually be installed in just one day.

Our underground storm shelters all have solid steel benches and removable steel steps. We design our two-piece removable sliding lid system with two things in mind. Protection comes first, then the ability of several exiting options in case of entrapment. Both doors are removable. In addition, each unit contains a winch and available hydraulic jack system  for exit assistance if entrapment occurs. The design of our underground tornado shelters provides you with the best protection on the market. Therefore, you will have the peace of mind knowing you and your family are safe during even the most violent tornadoes.
