3 Types of FlatSafe Tornado & Storm Shelters

Whether you choose our HDPE shelter or one of our steel shelters, we GUARANTEE that it will never float. FlatSafe Tornado Shelters are back-filled 100% with ready-mix concrete (NOT dirt) to counteract buoyancy and flotation of the installed shelter.

Each option provides its own benefits and options. Not sure on which is right for your home and budget? Contact our dedicated shelter experts.

Single Piece Lid System

All of our in ground FlatSafe Storm & Tornado shelters come with our patented single piece lid system. The lid is ¼” thick steel plate with added structural tubing to provide extra strength. The single-piece lid is larger than the frame of the saferoom opening and sits above the frame, not down inside the frame. Our lid system is MUCH stronger than the typical 2-piece lid system offered by everyone else and provides more than adequate ventilation to the occupants.
