Here where I am, the water table is about 6ft. Hard to have a basement when you have water 6ft down.

A cement safe room on a slab, will still be safe if built properly.
They showed a home this evening that took a direct hit from a monster storm, and they huddled in an above ground cement room. They came through it fine.
There were ten or more people.
The home built around that room, completely gone. You couldn’t even tell there had been a house there.
