The Atlas SAFE-CELLAR was designed to be installed under the concrete floor of a new house. It provides a Safe Room, Wine Cellar, Gun Room, Tornado Shelter, and can be equipped with our Nuclear Biological Chemical warfare package to serve as a modern NBC shelter. The steel structure is shipped in one piece and craned into the hole. Once in the excavated hole, the underground air ducts, water pipes, electrical lines, antenna cables, solar cables, sewage line etc. are installed. After ducts and lines are installed, the shelter is backfilled with stone and a 28-inch thick concrete slab is poured over the shelter to provide mass and radiation shielding. The SAFE-CELLAR can be installed under the kitchen, garage floor, closet floor, spare room, or living room.
