Frequently asked questions
How long have you been manufacturing and installing storm shelters?
Has your storm shelter been tested at Texas Tech University Wind Engineering Institute and if so what were the results?
Have you ever had any storm shelters leak if guaranteed against and if so how many, and what did you do to correct the problem? Ask if you can speak to a few individuals whose shelter was repaired or replaced.
In the very small percentage that this has happened we have stood behind our warranty with the shelter being repaired or replaced.
Has your shelter been designed with the help of a qualified engineer?
Southern Illinois Storm Shelters, Inc. had extensive help in design and development from a local University School Of Engineering on our new design.

Some competitors say fiberglass is old technology and is not a superior product. What is the truth to this?
Our 20 year track record speaks for itself. There are thousands of fiberglass shelters in the ground and have been for 20+ years. Concrete will crack and leak over time, Steel will rust, and polyethylene can also fail.
