I could build one hell of a bunker for way under the 'mini bunker' price of 39,000
Problem I have with a bunker mentality is whether or not I would be close to it when I needed it. Would not mind having a small storm shelter, but that's all I need. If it is bad enough to need one of these things, then I am living in the wrong part of town.
My son buried a 20 foot container, for a total cost of $5K.
$2K for container, $3K for mod's & burial.
Cut a 4x4 hole in the roof, preferably in a corner & recover with a good lid & ladder.
Just dig a 10 foot deep hole, with a ramp leading into it.
Back that puppy in there & cover it up.
Don't forget to mark where your entry hole is.
Be creative as to your entry.
You now have a cheap 8x8x20 buried treasure.
I have 2 buried now, one for god knows how many years, one just recently. Maybe in Ireland we get the better containers, but neither have shown any sign of bowing at all - and they are close enough to the lake that you could drag them out with a barge. Very wet, clay soil.
Just storage at the minute for the concealed one, for the expensive stuff like outboards and quads - the other is half-buried for general use - patio furniture, small RiBs, etc.
All I do is dig them out, then backfill with a very rough mixture of 6-12 to 1 not particularly well mixed (shook up in the bucket a few times, then dumped in) soil and cement. No founds, no nothing - and they are fine so far.
