For 8,000 you could probably build your own underground bunker. It needs to be erected with a forklift, not something you could store in the rucksack then.

It's not really portable or fast...
it took a forklift to deposit it
then you need a car to assemble it/pull it out,
then you need to to inflate with and electric fan,
then you need to hose it down with water which might not be so readily available and wait 24 hrs for it to harden.

The parts where it said it's fireproof and can be covered in earth/sand to be thermally insulated were pretty cool. Still in an emergency situation it's a bit more hassle than what I'd be looking for. Maybe it could be like an outdoor cellar if you entomb it in dirt

Don´t get me wrong buddy ! it´s a great idea and quite possibly in many situations a great form of shelter. I do tend to agree with the other poster though, if you where in a sticky situation it might be more hassle than it was worth. Hopefully none of us will need this form of shelter in the future. Peace.

Obviously, this isn't a speedy setup, it's for creating a hidey-hole bunker.

I agree that you could probably build your own for that much, but would it withstand as much wear and tear as this can? I think that a little planning ahead and setting one up in a remote location now would greatly benefit you in the future.

Some rebar, concrete blocks, and pourable concrete...yeah, I think that would stand up pretty well...and be fairly cheap to make.

dont give fema any ideas

personally i have looked into insulated concrete forms

from what i have read they go up fast and are just as strong as pouring

concrete is the only way to go for bunkers next to salt mines and digging into mountain rock

Nice thread. F+S. Saw this mentioned in a thread a while back, and it is deffinately worthy of a thread of it's own. Great thing to use to make/start a hidden bunker. With a little work it probably wouldn't be very hard to conceal, just got to make sure that grass or bushes wouldn't grow into it and destroy it.

S&F. I know this is an old thread but I just found this concrete canvas on the internet. Did a search and found this thread. Good. If it wasn't already here I would have started one. Thank you for finding a price range. This company is one of those annoying ones that wont even post an estimate on their website. tyvm!

The implications of this are disturbing but the applications are vast. The interior can easily be made into a sanitary environment... 2 men to set up (even the large unit) and 24 hrs to cure. So basically with enough manpower and equipment you could set up a military base with just about a day's notice... and have it camoflaged and concealed within 2 days...

Need to build research stations in the arctic or desert... 2 days.

Need emergency shelters because haarp keeps inadvertanly making natural disasters catastrophic... 2 days.

There are scarier uses such as building and concealing concentration camps within just a few days and if you do it quickly enough and time it just right even the spy satellites won't see you... but let's not talk about that okay... Any advance in technology can be misused... after all nuclear technology can power a city... or destroy much of it while poisoning the rest. I'm going to try and focus on the positive.
