Say someone wanted to bury some items for an extended amount of time and did not want them to corrode, but wanted them to be in serviceable condition condition upon extraction from casche. Any suggestions on design of fictional chamber and preparation of possible contents?

Dip in vat of cosmoline, shrink wrap, bury in sealed container.

Why would you want to bury anything. As Tom Gresham puts so eloquently, the time to bury is the time they need to be dug up and used....

I really liked the one from Terminator 2...:smokin:


it would be kinda noticeable build in front of the neighbors though. (provided you have close neighbors)

To play the devil's advocate...what if you had enough "stuff" that buying 4 or 5 safes is not really economical?
:homer:

and when you have too many to use ? :flipoff2:


And no, that does not mean you can use one :laughing:

for semi-permanent storage cosmoline or heavy grease is the best, but it will not be "ready to use" to say the least when you dig it up :laughing:

Ready to use: large pelican case, and as much dissents/O2 absorbers as you can stuff it it, latch, seal in heavy mil plastic.

geocache my ass.:flipoff2:

Just a thought to add here. Make sure you have an alternate method of locating your geocache. It is entirely possible that when you want to find it again, your gps may not be functional (old technology or no functioning satellites). Be a bad deal to know that your "cache" is out there in the forest somewhere, but you can't find it.

Noted that the guy in kwranglin's link used nitrogen in his tube. An alternative might be to use an oxygen absorber pack. I've only seen them for use in dry-packing grain for long-term storage, but they have to be available somewhere.

i would coat metal parts with oil and place in a heavy duty vacuum sealed bag with a desiccant. then place individual vacuum sealed items in a larger hard container.

Well you can also use a new/old big rig inner tube cut it so it is the length you need as this will be the outer layer/shell and seal up one end with tie wire.

use packing grease to cover all steel then wrap it all up with seran wrap and then one more coat of grease and put it in the inner tube and seal up the end and start digging :D

or you can use desiccant and not the grease in a sealed container if you go this route use more than you think you will need.



Oh yeah punch a post hole type hole as to have a smaller profile just in case and in the 80's-90's it was called mid-night gardening

What about something like Terminator 2, but just cement it in? Or something...

My buddy owned a bunch of property 10 years ago and the couple hundred acres next to him was owned by Hell's Angels. On day he saw a Uhaul truck pull up. Then all night long he could hear heavy machinery. Next day, no more Uhaul :laughing: They buried it and were making drugs in it underground :eek:

Get a septic tank.

Get a septic tank.

Wha? I'm talking about an underground shelter with cement walls that's sealed so water can't get it. Then seal the entrance off. Why not!?

Don't you recall the car that was sealed in a similar concrete chamber that was unveiled in the midwest last year? The results pretty much sucked - concrete is a pretty crappy "capsule".

Thats because the porosity allows water in without a vapor barrier

schedule 40 pvc tube to fit
two endcaps
primer and adhesive
spray cache with WD40, stuff inside tube with O2 absorbers
seal

you can get a fiberglass septic tank and modify it. just have to make your hatch air and water tight. it would be a little work but it could be done.... there a little seapage inherently with those things but you have a good shot of sealing it all out...

So you'd want to elevate/suspend the interior items to keep them from sitting *in* any collected moisture, as well as taking the already mentioned precautions to seal and use desiccant.

Much better than concrete IMO. You could spray the outside with a rubberized coating, and possibly the inside. Fabricate some shelves, put all sorts of junk inside it and seal that bitch up!

how much would it cost to have the entire exterior of a 20' shipping container covered in Rhinoliner?

yeah, i agree with it being better than concrete. its cheaper too, plus easier to move and they can be had in all sorts of sizes. if you wrapped the entire outside in an impermeable liner on top of some sort of exterior lining attached directly to the side of the tank. Also, you can "wipe" the inside with some quickdry sealant that is used inside of manholes to make sure they are air tight and can be vaccum sealed. dont know what it would take to get it to adhere to fiberlass though.

They also sealed that chamber with asphalt. I think that was as much the problem as the porosity of the concrete.

We need build photos. :flipoff2:

If you did it yourself, I bet you could cover the whole outside for less than a couple grand. That's not counting what you spent on prep work, depending on the condition of the container.

But they also I believe only put a tarp over the car and thats it and then surrounded it with concrete. It was a damn shame how badly that car rusted though.

IIRC, the concrete settled or something and cracked, leading to a very early, although unbeknownst, demise.

More off topic but heres a video and more about that car. That was a good looking car when they buried it.

YouTube - Buried Belvedere vault full of water (http://www.youtube.com/watch?v=ETwNR4lNW18)

Depends on what it is.

If you want ready to use get some hd vacume bags, O2 obsorbers, and dissicant from some of the survivalist food prep places.
I like the idea of a sealed PVC pipe safe.
if you are going to glue shut the thing, Get some plasti-dip and some hacksaw blades. Coat the blades, and after cured duct tape to the outside of the container. that way if you are really in the shit you can still get the thing open.
After recovery that 'container' can be used for water storage.

If you remove the pistol grips or other parts to get things to fit into your container, Make sure the tool to reattach is with the weapon.
You can vacume pack individual loaded magazines.

And my point remains:

The "best practice" of today may prove woefully inadequate tomorrow after who-knows-what has happened.
