My favorite CZcamsr always teaching me something
Really? I am your favorite CZcamsr???? no way I suck at this shit lol
@@AtlasSurvivalShelters you have really informative content keep up the good work!
@@AtlasSurvivalShelters Actually, you have great videos. I've been watching them for hours. Being yourself is what people like, I believe.
I believe the concept is called “earth arching”.
This was a great demonstration
Awesome
Thanks for the info, very informative
Nice video! Keep em' coming 👌👍
Great video!!!
Damn giants jump up and down on top of my shelter....
i swear to you i thought the same thing in my head right before i read this 🤤😂

Great Video!
Thanks I notice you always watch my videos and comment on the bad people Thanks for having my back buddy Ron
I work on the pipeline, we do compaction at 6” lifts 12” seems to be a little too much to get proper soil hardness. I guess it depends on soil type. A, B, or C soil
Great Video.
The 15 Thumbs down must be friends and family of competition "S"...
oh my word, if only i had the money :( my shelter design would be mint! alas i live in the uk and broke :( never mind, in another life maybe lol. love your shelters btw :) much luv from the uk :)
I feel the same right now i am in germany. Its expansive here and iam sure you need alot of paperwork to get the permission.
But I also do have some nice design in mind...maybe the lottery will help me :-)
Excellent video Ron but what I would like to know is instead of compacting soil around the pipe if you poured concrete all around the pipe and a few foot above it would that make it stronger than just soil
green magic great question, I wondered that myself
yes. look up stainless steel fiber reinforced UHPC. concrete's enemies: aggregate/ mix design, chemical leeching and intrusion/ acidification (porosity), lack or geometry of reinforcement, rusting corrosion or debonding of reinforcement, improperly engineered geometry
Great idea radar resistant
door and hatch seals need to be better
Good
I'm a welder/ boilermaker!! Do you back grind and weld both sides? Do you repaint welds with galvinized paint??
galvanization is a cop out. the layers are there to act as sacrificial anodes along the whole surface, or as a simple barrier layer in non-hostile environments. it is not truly durable
What if you encase it with cement?
This looks like it was filmed back in the 90's and broadcast on public access TV still relavent today though nonetheless!
He stands on tip toes on one foot. and then stands flat on both feet... It doesnt take an einstien to know youre transferring 80% of your weight to the surrounding dirt and not the Shelter Itself. Not Saying Its completely incorrect Im just saying Thats inconsistent.
right. has more to do with unsettled dirt not providing a strong enough arch since the particles don't touch or transfer the force very well
@@Baigle1 I mean i watched the video pal... doesnt change the fact one time hes literally applying easily 230ish pounds over the Surface area of the Tip of his boot... and then once the dirts Packed He distributes all of his weight Evenly over the Surface of the Packed soil. The inconsistincies Bothered Me. If i were mentally incompetent id thank you for assuming i dont know what im on about.
yep. hard to judge where a comment comes from. most are lacking the basic understanding. however you feel, it doesn't matter. drop in the ocean. will continue on as usual
I LIVE IN SAINT AUGUSTINE FL,DO YOU SET UP YOIUR BUNKERS IN FL?HOW MUCH DOES 1 COST?
Would pouring concrete on the sides of the pipe make it last longer or allow it to be installed deeper?
yes. just choose a strong, durable mix design with proper reinforcement that won't leech acidic or corrosive materials into the concrete over time (non-porous cured). search UHPC.
I'm watching Pete and Bob pound sound at 5 am. When I get a shelter I'm gonna crawl in it and die.
Road Center, Road Commission, Dept of Roads? Same?
My question was is hydro packing and acceptable alternative. Ie wetting down the ground so it turns to basically mud and settles. I understand there's the challenge of keeping the pipe from popping up out of the ground in such a scenario. That's my question though.
wetting it down after compaction will probably help stabilize the earth more, not too much water.
Compaction is very dependent on the moisture content of the fill material. To little moisture and the fill material will not consolidate. To much water and the particles in the fill will be held apart by the water and not reach maximum compaction or may not compactat all. You realy need the fill to be compacted when it has the right moisture level for that particular fill material. That is why test labs test fill material then come out to the job site to test how well the material was installed. But a fair generality is water will wash 1/4 minus crushed rock under the pipe after the pipe is in place. Then use larger rock to completely surround the pipe after the water has drained away. Be aware that if you bed the pipe in concrete then change to a different back fill material right at the change point there there can be a serious corrosion problem. That point should be protected with a mastic or a 20 mill plastic tape for a few inches either side of the change fill material. This can also happen where the metal pipe crosses from rock fill or native material in to a protective concrete pad at ground level.
galvanic corrosion series is the worst
If you were to encase one of these shelters in a concrete shell, I wonder how long it would last
as long as the concrete remains intact (proper mix and reinforcement design) and the alkalinity doesn't acidify or corrosion occur, you can expect it to last thousands of years, as some mix designs are as strong or stronger than the hardest granite. search UHPC
You have a shelter? What is it like
I want one
If you were to fill it with concrete instead of compacted soil would that work even better?
yes. see my other replies.
Pretty amazing, peaty can even eat a few more doughnuts...
It wouldn't matter
Is the shipping and installment cost included in the price?
No. That depends on what size bunker ? How deep ? What sort of ground your digging into ?
He went on the ball of 1 foot for the non compacted but not for the compacted and used 2 feet for the compacted, thus about 5 times more pressure on the non compacted. Not an accurate test. You can see that compacted still wants to crush if he used the same amount of pressure
What about sled outs
What if instead of packing down earth, I buried it in concrete? Would this work?
Yes concrete would work, but it's expensive. Properly compacted soil works just as well, and it's much cheaper.
What about removing moisture inside the Atlas Survival shelter? Moisture even from peoples breath can cause condensation. How do you remove the moisture?
The bad air is pushed out when clean air comes in.
What about a poured concrete under and surrounding the culvert? Would this offer more protection/stability?
if you do it right. see other comments i've replied to.

Ron how deep? Grand solar minimum protection ...
I tried calling your toll free number. BUT it said that your number is not available to be contacted from my calling area.
Are you selling this abroad too?
Yes.
If one concrete it in what will happen?
I wander what is the max earth quark it can withstand
What about earthquakes ? Is there any test or data about that too ? I mean in california it might be a important question.
Your biggest concern in this context would be be soil liquefaction, this is most likely to occur in uncompacted, moderately saturated, granular soils. Since it's probably not cost effective to change the soil type, your best protections against this are good drainage to keep the surrounding soil relatively dry and soil compaction. If you're particularly concerned you might want to excavate down a few feet below the base and put the soil back in 6-12 inch lifts, compacting each layer ideally to 95% but at least to 90% of the modified proctor density (ASTM D1557). And make sure you have good drainage, keeping the soil around your underground structure relatively dry is probably the best thing you can do.
Granted, most my knowledge is related to underground culverts, not bunkers, but I don't see why the same principles wouldn't apply.
@@costakeith9048 compactionis anyway very important of course. ..but why a cementation of the complete bunker this should also help against to much water like they do with a tunnel
@UC1vlJ_PjZAIP_gCZSNZWyfg thx i just need do more research about underground construction technique. Till now i just liked the bunker design and even researched the air system.

Good video, but chances are, you're not going to put your shelter where there's any sort of major foot traffic, let alone vehicle traffic. Never the less, compaction is very important for the sake of radiation protection. You need compacted soil to stop radiation, and the denser the material, the more protection. Concrete is very dense, and provides great protection, lead is even more dense, and of course provides more protection, loose soil...not so much. Keep up the great work.
Have been looking into these shelter types for weather issues... but, now re-thinking as I see that protection from foreign sources may also be a necessity? Please tell me I'm not seeing things : Seeing Russia increase a military presence along its borders, and now Sweden informing their citizens to know how to prep... czcams.com/video/YCAJofc4ajM/video.html --- has got me thinking I'm either seeing things incorrectly or...
Making shelter radarr resisted
you posted twice
Virtually all road tunnels installed under hills, mountains and rivers are tubular in design, that alone should tell you something about strength levels.
try telling that to the competitor lol
Ill just do a gentle push.. Adds entire body weight so much so he is worried about breaking the glass...
but isn't that shelter too small for a person to live in?
Being an engineer tech that deals with this stuff day in and day out
This is a awareness video but also not a very good video because it's mislead for someone doing this sort of thing
Many factors go into this typ of work
Height of lift for compaction is rated by size of pipe
Compaction % of rate can only be known by testing each lift after is compacted and that is not easy as it's done with a government regulated nuclear operated device and the soil gravel and or granulars must be lab tested first to find out the ideal % rate of compaction
Width from pipe each lift has to be
Over compaction is worse then under compaction
Moisture levels needed for rate of compaction again must be lab tested first
The list goes on and on as the things needed to do before you just rent a tamper and start beating yourself to death compacting materials
Always use finer granulates beside the structure
Beating rocks into the side of a structure is not a good thing to do
is there a good set of videos that describes these factors, and their importance, that you can link to?
surely if your compacted earth is confined by a retaining fiber or mat then the overcompaction matters less as it would be unable to wash out for the life of the mat or mesh?
Not sure about videos as I have never looked
As for using fibber mat yesxit would help from material being washed out depending on what your backfilling
Something els that should be mentioned is the fact that the earth under a structure or pipe should also be compacted so the weight of the structure and compacting material beside the structure does not move the ground under it
You can find a local testing lab that will run an ASTM D1557 for you for about $200-$300, it's well worth the investment. This will give you an optimum moisture content as well as a maximum density. As for compaction testing, you can generally get someone out there for a day for under $1000, but most technicians in my experience aren't particularly reliable for trench work, so your mileage may vary. You can always get Sand Cone equipment for a few hundred dollars and measure compaction the old fashioned way (which is often better in trenches unless your technician really knows what he's doing with the nuclear gauge), just practice it a couple times first and make sure all equipment is turned off and there are no vibrations when performing testing. As for lift thickness, you can always go down to 4-inch lifts if you're worried though 6-inch lifts are generally fine, 12-inch lifts are unfortunately not uncommon and allowed by many state specs.
One thing to keep in mind, most the stresses that culverts encounter and most the problems one sees are a direct result of traffic loading. If there isn't going to be any traffic loading above your bunker, you won't have nearly as many problems with it as you would with a culvert under a roadway. But one big thing to consider that many people overlook, even in culverts under roadways, is drainage, you want water to drain away from your bunker and you want to do what you can to ensure the soil surrounding it doesn't get saturated; if you're going to have landscaping over it you might want to develop some underground drainage system to move water away.
Being in Canada your prices in the USA very and from what your saying and what I know from working here they very allot.
Thanks for your info on the subject as it does very from USA to Canada
Side note I hear you on testers
Yes many are not worth having
But I guess it's why I work jobs start to end as no matter what I am doing it's done correctly
Where does poop in bunkers go to
Septic tank !
While the principle is accurate this test is bogus. Watch where the ball of his foot is on the "smashed" pipe versus the flat foot approach of the tamped pipe.
When you transport these shelters, do you tarp them for anonymity so nosy people like neighbors and passersby's don't know what's underneath? I'd rather outsiders not know what I'm doing.
Nope no tarps to big and we come in the dark usually
Where does that poo go lol
goes in the septic of into a composting toilet
@@AtlasSurvivalShelters thank you I was curious where all the drain water from showers and toilet went
