As the title says... looking for a relatively inexpensive tornado shelter solution. I'm not really after a plush and comfortable "doomsday bunker" that I can live in. No, my interest is in getting my sons and myself underground safely in a tornado.

I grew up in West Central Alabama, and if you drive around in the country, you'll see "storm cellars," as we called them back then and there, all over the place.

Now I live in East Tennessee. We have far fewer tornadoes here, but believe it or not, there's a slight downside to this, and the downside is that there's no one within a hundred miles of me selling a decent shelter at a decent price. That's because by the time I had one shipped here, it'll add at least another $1000.00 to the overall cost, plus I'll have to hire a septic company to bury it for me. Between digging the hole and backfilling, that'll be about another grand. The old "price includes installation" thing doesn't apply for me.

I'm not really into the whole indoor "safe room" concept. Even though most say they're rated for 250 mph winds, I can't help but wonder how they'll hold up to the neighbor's tractor hitting them at 250 mph. There's a bit of a difference there. My interest is in strictly underground. Besides, my house is a framed type with a crawlspace, so the only feasible place I could put one of these would be in the garage on the concrete floor, and that takes up apace.

I've considered the storage container idea, but I figure by the time I get welding equipment, learn to weld, buy the scrap steel, and reinforce it, I've spent enough to just buy a prefab steel shelter and have it shipped.

But then again... a properly reinforced buried container would have much more space and be nicer overall than a prefab shelter, plus it could hold more people and I could also use it for storage.

There are several other concepts I've explored:

1. Buy a used dumpster, bury it, and pour concrete (with rebar) around the bottom three feet or so.

2. Just straight-up build a concrete block shelter.

3. Just bite the bullet and finance a steel prefab shelter and call it a day.

Input is appreciated!

8' dia. culvert (steel or concrete). You have to close the ends but this gives you the advantage of having two ways in and out. That is good planning.
I'm very interested in the culvert idea, but with a slight twist. Rather than laying it horizontally, as most people do, I would love to find a piece that's 10-foot diameter by about nine or ten feet long, then pour a round concrete base and set it in vertically. I assume there are pre-made caps for these? If so, I could get a cap and cut an opening for the entrance and a smaller one for an air vent.

But so far I've had very little luck finding anything less than about 30 feet long for $10k or more.

I'd check with the TN dealers for >>>> Tornado Shelters | Southern Illinois Storm Shelters | United States

they manufacturer a variety of shelters in S Illinois and stockpile the popular stuff with their dealer/installers in the surrounding states - you'd be sharing transportation $$$$
Thanks, but I forgot to mention that I really don't want fiberglass. Even the little 4-person Storm-Tek is usually $5k and up. They also require some anchoring to prevent them from floating up.

Good thinking, though.

Rent a backhoe from Hone depot (300 for a weekend)….. Spend a weekend digging a hole, Pour a floor, build the wall forms out of plywood….. Pour again, make sure to notch out 4 spots to put 2 wood beams across the top, pour a ceiling/roof with an access hole…… Finish how you like, bury.
I bet you could do a 10x10 with rebar for 6-7 grand ( that’s here in PA, I bet cheaper in TN) You could do it in sections therefore financing it a month at a time. For 200 by us you could epoxy coat the whole inside to further waterproof it.

if you want to go that direction - look for old storage tanks - crapped out for that purpose but patchable to be waterproof - an end or top operable hatch >>> just need to be careful about dangerous residue

I did not check prices, but something like this? Maybe find used or never used/old inventory from a city nearby? Although you may die from claustrophobia.





Contact the cartels in mexico and see how they build underground tunnels?

I've thought about just driving around and looking for dirt construction sites.

"Hey, I'll give you $500.00 for this and another $500.00 if you'll haul it to my backyard."

I posted a series of photos from the construction of my ICF basement. Perhaps you could build a smaller version, connected to your existing home.

Since you only need it for very short times, why not just dig a storm cellar like they used to (and add a few modern safety things)? Shovel-dug hole in the dirt under the house with an angled door and a latch inside. Keep wipes, TP, plastic bags, case of water, first aid kit, fire extinguisher, flashlight, weather radio with power output capability, batteries, axe, air horn, whistle, and a couple bottle jacks inside. Maybe an old cell phone (911 only capability). All fits in a milk crate.

Garden-type back-hoe with long-reach, you could do it in an afternoon (unless bedrock too close to the surface).

For those that don't know what 'm talking about, first part of Wizard of Oz.
