Picture of How to Build a Super Top Secret Bunker Under Your House.  the Prelude...

EDIT: 07082012  Finally gonna finish it up in next few weeks....

Another vid! 

When I built the house I just spent 7 years working on, I had a lot of days that were just plane monotonous, so I would daydream about the Next Great Project as soon as I finished the house...

If you're OCD you know exactly what I am speaking about.

Perhaps it was watching too many reruns of Stollag 17...

Maybe it was all the Underground cabins we built as kids to have a cool place to hide out in the summer.

Truthfully though I just love to build things and when I designed the house I made the bottom level only half the size of the main floor and the other half is a crawlspace about 4 foot high.

Most of my plumbing and stuff runs around the floor joists down there so I wanted enough room to have access to everything but I didn't want to build an eight foot wall, It took me 7 weeks to do the block for the garage workshop and storage room so saving 4 feet of wall seemed like a good idea.

Looking back if I really intended to do this and had the wife's permission I could have saved a lot of bother by doing this first and I wouldn't have to worry about the house falling on my if I dug out too much from below it.

I didn't leave any vents to the outside mostly cause of wanting to be energy efficient and not have a cold room under one above I was trying to heat in winter. I did talk to the building inspector about this and convinced him I could put a gable vent fan on a timer at each end one blowing in and the other blowing out to ensure a good change of air so it never mildews. I intentionally made it to push air into my workshop and draw replacement air under the house at the far end of the garage. This way in the winter when I am using the wood burner if I am working on something I can open the duct to the workshop and close the damper and the heat travels in a big circle across the garage into the crawlspace and then back into the workshop to circulate the heat so I can work on something midwinter if it is 40 out with a t-shirt on.

I got lost in a Blizzard when I was abut 20 for 23 hours and was 31 miles from where we parked when found, so I don't do cold anymore...

When I laid out the supports to the crawlspace I left a wider gap between two of the columns supporting a beam since the crawlspace is 20 foot wide and I didn't want to pay to special order 20 foot 2 by 12's and I just happened to have gotten a deal on a couple 40 foot beams delivered by accident to my house and unloaded before we discovered they loaded the wrong ones and were two thin to support the bottom garage ceiling. They sold me them to me at cost when they delivered the proper beams a few days later because it would have cost them money to rent a piece of equipment to lift them back on the truck.

I also filled the back of the bottom garage wall wide enough for a ten foot door and didn't put any rebar in that section. All the rest of the bottom level block has rebar in ever other hole and is filled to the top with concrete instead of just every 4 feet as code calls for. I will be able to saw this opening or get some of that ACME black paint they use to make tunnels and then start digging with a bobcat and dumping the dirt on the slope behind the pool so its not as steep a grade since I use a push mower for the exercise.

Step 1: Different Methods of Moving Soil and Reinforcing Sides

Picture of Different Methods of Moving Soil and Reinforcing Sides

When I started thinking seriously about starting this I knew I had to do a few simple tests first that would cost me a bundle if I had to hire an Engineer and do them even before I applied for a permit.

They'd want to know the different types of soils, how thick each seam was and most importantly I wanted to know how far down the water table is.

I live in Florida and generally if you dig a hole a few feet down you'll hit water but I'm in the Panhandle of Florida so we actually have some hills here. The lot slopes to the lake enough I was able to dig a bottom level into the hill giving me a pretty safe place to hide if we get a bad hurricane. The house is extremely reinforced and all the walls are shear walls meaning at least one side has plywood glued and nailed every four inches, including a second layer on the inside of the outer walls which also went a long way to soundproofing the place. I have more anchors than required and threaded rod going from the footers to the trusses including the interior walls.

The molding work on the ceiling of the great room is actually tied into the roof trusses and the floors are all 3/4 plywood tongue and groove and glued and nailed plywood every four inches for a subfloor. It's covered by 3/4 by 2 1/4 Oak tongue and groove running perpendicular to the floor joists. The Kitchen, Halls and Bathrooms I tiled but the bulk of the house has the Oak making a very stout roof for the bottom level.

My workshop also has plywood ceilings so that part is especially strengthened to the point of a tornadoes shredded the top two floors you'd be safe huddling under the work benches.

I tend to ramble because I crushed my head three years ago in an accident so back to the intended topic of how to dig a hole under a house and not have it fall on me.

My primary method was that I felt I could safely dig along side of a footer and pour a 2 foot high concrete wall so long as I did it in stages the sides would not cave in for a few day, especially if I misted it with water from the hose. I drove rebar about a foot into the sand or clay and left the rest sticking out the top so the final bottom to top pour would bind everything together. I also after the concrete had dried and I had the forms moved down another 2 feet I would use a small spade to find the bottom of the previous rebar, and using a piece of pipe for leverage I'd bend it into the area of the new pour at a 45 and then bind it to the rebar for the next pour. The end result is a very solidly secured concrete wall 10 or 12 feet high shaped like an inverted wedge to discourage it from sinking into soft ground. Also I decided to only do 10 or 15 feet at a time but never the length of an entire wall in one shot so I didn't have the sides blowout like in a mine accident.

I spent 7 years building the house I don't want to cause it to collapse and the wife would never let me hear the end of it.

I then figured I could keep repeating the process essentially forming a very tall staircase and when I had enough head room I'd pour a final layer 8 or 10 feet high to tie it all in. Billy down at the building department would have a fit if I told him I wanted to do this and I'd need a real engineer to put their stamp of approval on it and it's not the type of job you can start and walk away from halfway done if something comes up, so this is too much for me to do as a solo project and I;m not actually Licensed Florida Contractor.

I did figure I should do a test shaft to see if it actually worked and get a record of what was down there and I would definitely need to know the water table height and the thought of having to assemble a mini drill rig in a crawlspace seemed pretty expensive but by staring long and hard at it for a time and a day, I decided I could dig a shaft by hand right next to the access port and cover the stairs with a snug piece of plywood then shovel it out the port onto the stairs then into wheel barrows and dump it out back.

How hard can that be?

I had a limited budget but I do own a mortar mixer and had a great stockpile of rebar and three inch pvc pipe left over from something I cannot recall and some lumber I'd used already for concrete forms and yes there is a Plus side to OCD especially if you have the room to store it until you need it.

I chose not to mention to the wife what I was planning mostly because she would have said no but I had just about used up all my savings finishing the house but I still had my emergency $1000 so I did some math and bargained for a lower price on 80 pound sacks of Redi-Mix if I bought 6 pallets and so I snuck a look at the wife's calendar to see her next doctors appointment and her caregiver would drive her so I set up the deliver for when she was gone and had a space cleared in the bottom garage that I could store all of this, and had some pieces of pipe on hand to walk like an Egyptian and move the 3000 pound pallets to the far back of the garage by rolling then and then using the next pallet to roll the first to the back until all six would be safely hidden inside.

The wife was running late though and they showed up just as she was leaving...

Fate Strikes Again but my wife knows I was still not quite right in the head in fact she'd say I was like that even before hitting my head and is used to me just jumping up in the morning to start working on something and I did after all build her a house and miraculously she didn't ever really ask me what the cement was for.

Once I had the cement I thought about forms and I decided if I am to do this and make a 2500 square foot bunker I need the forms to be modular so I could keep reusing them over and over.

I decided on a few basic sizes, 2' by 8',2' by 6', 2' by 4', 3' by 4', and I made them with the braces in each size identical so when I needed to make 50 of these I could drill around the perimeters in a standard pattern so I could just bolt these together, pour the concrete, then unbolt them the next day and move on. Trial and error taught me that staple gunning a smooth layer of 6 mill plastic makes for a much smoother wall than plain plywood and you just need to replace it every few pours.

With the forms made and the 6 yards of concrete safely hidden and covered with a tarp just to be safe I started digging next to the access port so I could get some standing room. The first five feet of soil is sand I believe referred to as Orange Ruffie but I'll need to check my soil survey of Walton county to be sure.

Regardless sand is pretty easy to shovel although the very top layer was had dried out pretty solidly and had some clay mixed in I had to spray it with the hose to soften it up. You actually need to keep the sand moist or the sides will cave in quickly and I made a point of misting the ground before I quit working on it for the day.

I made this approximately 7 by 7 since as I went deep it would get narrower and I was about 18 inches between two columns supporting the beams so this was a good spot to test. On the first 2 foot pour I also poured and formed a beam between the columns with a lot of heavy angle iron cut to fit tight between the columns.

The I started getting the hits from The Office of Homeland Security which I figured was just because so my of my traffic comes from Walter Reed Hospital and the rest from our troops abroad.

Then the cable company knocked on my door and said some magic piece of equipment let them locate the source as somehow coming the crawlspace under the house and they needed access under there to check for problems...

Step 2: Ten Yards of Sand by Hand Out in the Yard

Picture of Ten Yards of Sand by Hand Out in the Yard

I made a big dent in it, the hole not my head, but that to has a dent but only the size of a tennis ball.

A mere dimple compared to shoveling out 10 Yards of sand by hand.

For a time the pick and shovel bumped the floors joists and my wife started asking about the noises where? What could be causing it and well and this is actually true I have a perforated drain line that runs around the perimeter of the monoslab making up the garage floor, about 40 yards of concrete and at times of heavy rain the water would sometimes back up this pipe and actually cause the bottom row of block to wick some moisture out so one of the factors in choosing this location was that it was in the center of the drain line and I figured when I found it I'd think of something and when she asked of the noises I thought well I'm just digging a hole to run that pipe into so it drains well and keeps the bottom level dry and patted myself on the back for being quick on my mental feet and actually coming up with a valid reason to dig down there.

By now I was pretty proficient in digging using the tower of babble approach and was getting strong again but really 10 yards was making me wish for a better way and then I looked at my 3 inch trash pump and the pile of three inch pipe and by now I had gone down a good 4 feet below the bottom level floor and had hit a seem of very water impervious clay that would hold water for days.

Sometimes you just get lucky!

I also looked up and saw my 1 1/4 central water supply line and added a T and a valve plus a spicket for a hose and I could draw up the max the 2 hp well puts out and fill the hole in no time then while its running start the trash pump with the flexible line in the drink and it pumped as much sand out as I could shovel in, slurry style and I could pump out a yard in five minutes or so plus I stretched the hoses out so it deposited the sand in the low spots of the yard I had always been meaning to fill.

It was surprisingly effective and on a bigger scale I'd get a second trash pump to deliver a large volume of lake water up to the pit since I had to constantly pause to let it fill back up with water.

It also ran my power bill up a bit...

I continued this pouring two feet at a time although you can go 3 or 4 feet without the walls caving in when dealing with clay but better safe than dead so two foot at a time and ever other 2 feet I drill a hole with a water jet at a 45 into the layer of clay then shot a piece of 3 inch pvc 5 foot long again with water, drove a piece of rebar about a foot into the clay past the pipe incase I ever ran into it from the other side I could tie the rebar together and ended up with 12 fingers extending into the seam of clay and tied solidly to the walls rebar so they could almost hover if you dug out from under them.

Once I had about 18 foot of headroom I jetted a ten inch piece of schedule 80 about 15 feet down so I could get an idea where the water would because and by my rough guestimate I was as low as the lake is high so I figured the water was near and sure enough it's almost 25 feet below the dining room floor, very unusual, and apparently the seam of clay is acting as a sort of underground dam since the seam follows the contour of the ground and free of the pressure of a layer of clay above it, it rises up the pipe to about 5 foot below where I stopped going down.

I did this to have a drain.

I would not want to come home and find the bunker has turned into a swimming pool because a pipe broke and the ten inch pipe filled with gravel would have been very effective and require no power.

OCD rears its head and I remember I have some 2 inch sch 40 and about 15 feet of 2 inch well screen and so I shot the well point down about 60 feet then filled around it and the inside if the ten inch pipe up almost to the top with gravel so nothing could fall into it. I temporarily hooked a half horsepower well pump to it and ran about 8 gallons a minute for 30 hours to get all the fine settlement out so I figure it should be able to drain almost as fast as it empties. Plus it could serve as an emergency water source if we ever get slammed by another Katrina and have to go a few months without power since only having to lift water 5 feet can easily be done with a hand operated crank.

Step 3: So in Conclusion...

Picture of So in Conclusion...

The house did not fall so I would say with a real engineer telling me how to place the rebar I can dig down about 21 below the dining room floor, there is a 4 foot crawlspace, 5 to 6 feet of sand then about 20 feet of clay sitting on top of the water table.

Two stories would be possible but I am thinking it would be better to have one floor with 12 foot ceilings with everything gently sloping to the drain in the center and I could have an easy 1200 square feet of tornadoes proof shelter, enough for the entire street according to FEMA. It's not likely that I'll build the big bunker since I'm pretty close to being tapped out, need a few more surgeries, and it's not likely I'll ever get hired to do anything since without a short term memory I spend a lot of time walking around trying to remember what it is I am doing. They would need to hire someone to follow me around and keep reminding me what I was working on at the moment but it might make for an interesting Discovery Channel Show...

LOL If you're gonna Dream a Dream don't ever cut yourself short.

When I had the accident I had the house dried in but it was just sticks inside no wiring, plumbing etc. Fortunately I had the siding on already since that took a month but I hadn't bricked the bottom level yet and I managed to do that in about 2 years by putting a white board up in the Foyer and every morning when I arrived I'd write down what I was planning on working on and I finished the house and relearned how to walk and talk since somehow I fell through the medical cracks and was never actually sent to any therapy or rehab but maybe it worked out better this way.

If worse comes to worse I'll just turn this into a stairwell and make an 8 by 12 foot room under one part of the bottom garage floor which according to
it is the safest place to build a shelter.

I just finished reading "The Tunnels of Cu Chi" about a labyrinth of tunnels in the area northeast of Saigon used during the Vietnam war. It appears that two things you would have to be sure of before beginning your little postapocalyptic hideout are the consistency of the soil, (the Cu Chi soil was hard enough to withstand tunnelling), and the other thing is the water level (the water level was sea level, (Cu Chi area was high enough it didn't seep in.) Otherwise, you would need to pump constantly, which would use up a lot of power. In some places, like suburban District of Columbia, the water level is about three inches down.

I actually started with a test shaft about 7 by 10 and went down into the clay and lined it with concrete I carried in 80 pounds at a time and telescoped it as I went down. When I had about a 14 foot hole I shot a piece of 2 inch pipe down using water and watched until I hit the water table and so I could see where the seam of clay ended since it's very water impermiable fortunately and appears to be 22 feet thick. When I built the house about I put an I Beam in the footer where the shaft is located and made it thicker and wider so I could tunnel under it and for now I have a simple tornadoe shelter that is dry year round. The clay works as an underground dam and I actually pulled a siphon up the hill from the lake and ran it into the bottom of the pit to get an idea of how much lower I was which was maybe 4 or 5 feet so eventually I should be able to make a bigger version and keep 8 feet of clay between me and the water so I don't need to worry about sump pumps as you mentioned.

One other useable thing that I got from that book was that the Vietcong made an occaisional room with a conical cieling. This worked like a megaphone to amplify sound going through the ground. You'd be able to know if someone was outside, looking for you, or if someone was driving over your hideout.

I wonder how they supported it? I know a dome is strong but only if it has a solid arch in all directions from the top and with just dirt or clay I'd be nervous to be stuck there listening... I bet they used Bamboo in places. I need to read that book thanks.

stiggle (author)thepelton2010-08-26

You'd just need to "tank" it to be watertight which is installing a waterproof membrane on the walls. Then you just have to be careful not to puncture the membrane. There is a guy in the UK who "tanked" his basement...

Senseless (author)stiggle2010-08-27

The only water problem I have is the five feet of sand sloping from the road to the lake sitting on top of the 22 foot seam of clay. Essentially I just need to grout around the shaft with portland cement a foot or two higher than the clay so the water just flows around me instead of dropping into the pit I dug in the clay which then filled with sand. It would be cool though to tank part of it and raise Bass I can get from the lake since I love fish and could fatten them up on corn or something and without predetors like catfish I could end up with a slew of them to share.

I do have one question have you thought of a way to defend the front door to your secret bunker?
I remember seeing an episode of twilight zone where Guy was discussing with his neighbors his bunker and how he planned to survive in case of a nuclear war all as neighbors laughed and said they would come and seek refuge in his bunker the survivalist told them that he only had supplies for him and his family and his neighbor should build their own at the end of the episode The bombs are falling the neighbors are breaking down his doors to get in !!
it's always got me thinking about how to defend the front door LOL

'Just stumbled on your adventure. Wow. Great write up. Loved following your thought process.

Your excavation process was clever. It reminded me of the method used by our local Public Works guys when digging around gas lines. They have a big vacuum truck with a water jet. They'd use the water jet to cut out the earth and suck the loose stuff up with their 6/8 inch vacuum hose.

I love this. When we can buy a place, maybe we can do something like this also. And if you're using more power suddenly, the utility company will report it as they think you're growing weed. Digging under a house would also lead them to believe you're growing weed. LOL

I used wood. I'll explane later.
I dug straight down for 18 ft. Then dug a 12X10 ft room with an 8ft celing.
For the guy who thinks you need lead to shield from radiation. Not so!
I'm an engineer having worked on Nuclear projects.
All you need is a good filter to keep out radio active dust, "that is what nuclear fall out is" you only have to worry about Gamma radiation.
A cinder block building will protect you from Gamma if you double them up.
I would if building above ground make a wall of cinder blocks with the holes filled with
either concrete or packed earth.
Then I would build another around this wall with about 20 inches of space and then fill the space with either concrete or packed earth.
Build for strength and build the roof with a layer of 2X12 inch cinder blocks. Some earth of approximately 20 inches then another layer of 2 inch cinder blocks.
Other than life support, "mostly filtered air" you are safe from radiation with this.
I went underground due to paranoia.
My hole is under my deck which is at my dining room level.
Below my dining room is a utility room that is the same size as the slab.
Extending out from my dining room door is a deck. There is a stair way up to the deck as the back entrance to the house.
The deck then extends all the way around the house.
Under the deck just exactly under my kitchen door is where I sunk the 36X36 inch hole.
The shape of the slab is not square. One side is slightly longer than the other.
The house is sided up from the slabe and the area where I have my hole is in the corner created by the long side of the slab and the short side. It just happens to be the slab is actually 42 inches shorter at one point. That is where I dug down. That made it easy to wall my hole in under the deck maiking it look as if the slab is square.
In side my utility room I have storage shelves along the wall that is the short part of the slab. I have redesigned the shelves so one of them is actually a live storage area. We store light stuff there, "cerial, rice, dryed milk etc." That shelf is actually movable as a hidden door to the top of my shaft.
I have storage for more than a year if I had to stay there 24 hours a day.
That includes my wife, ten cats and two dogs.
I have a way to dispose of the cat littter and other nasty stuff.
I have a filtered air system, including hand pumped back up system.
I have a "geiger/muler" tube monitoring system with one in my shelter and one exteded to the surface. The one on the surface is disguised.
I have an almost endless supply of water. I also have filters for incoming water if necessary to remove sediment that may be radioactive.
If biological I have CO2 absorbers and a large supply of pure O2 and monitors to know how much O2 to add as well as the level of CO2 in case I need to manually pump the air. I also have quite a bit of clean nitrogen to replace any lost over time.
My blend is nitrogen and O2.
I'll elaborate on the "how to" on digging this without getting burried, later.
Dig baby dig!
It's coming.
Not if but when. O
bama is putting the push on to destroy this country as fast as possible with his friends.
It is the absolute gole of the Progerssive, Communsts etc.
When it comes, I'm gonna be a casuality but the cost, "if I have my way about it" will be very very high.
I'm still digging, "expanding in sq ft." Off one conrner I'm digging a long tunnerl,
75' to another area for an emergency exit.
The shaft for the exit on this will only go up to about 3 ft below the surface and will be dug with renforcement on the way up.
It will only be completed if I need to dig my way out!
Thu Mole!

I have a perfect place for digging starting under the house, I purchased 5 acres on a hill having 360 deg. view, yet the hill is alabama red clay. A very tough soil yet i couldn't ask for better. I am starting the dig this weekend. I am an electrician and have the supplies for a battery bank and wind and pedal generated supply for the bunker using all LED's for some light. Thanks for your ideas and good will to you!

I have been thinking about this article for two years since I have first read it. I have always loved the idea of an "underground mancave". When I was young I used to travel through sewage systems and local caves (they were probably no more than medium size holes in the ground, but seemed much larger back then). I am now in a position to build my mancave. I bought a house near the beach in Australia and want to build a new home on the land. Once that is done I will not have the access for machinery to dig etc that I have now. So I have to build a mancave BEFORE I build the house. The trouble is I want to build a workshop over the top of it. I live in a very sandy area and have considered cinder blocks, rammed earth walls and other building techniques, but I'm not an engineer and am worried about the pressure on the underground wals created by the sand once I have backfilled and the weight (and possible collapse) of a concrete foundation on top of the structure. I thought about using cinder blocks filled with rebar and concrete every 10 inches with timber beams going across. The structure underneath will be about 30 feet by 15 wide and the workshop on top will be about 50 feet by 23 feet wide. I wanted to make a ladder and have the entrance through the workshop floor somewhere so I can have a safe place to go in case of a zombie apocalypse or land invasion by the evil dolphins! Any suggestions as to how I can ensure the structural integrity of my mancave?

im assuming that your house is in between 1200 and 2500 square feet, i also noticed that you rented a tractor backhoe, i work for an excavating company and it would have been cheaper to rent a full sized excavator, for the given size of the crawl space it could have been finished in two to four hours at 110 dollars an hour CAD. thats just my two bits.

Senseless (author)Jordan Dyck2012-07-04

You're absolutely right!

If I wasn't married I would have just done this first off for practically nothing time wise. I can rent most anything I need and yeah a loader would have been good but I needed the stinger to dig in a few spot.

The main floor is actually about 4200 square feet, the bottom floor is a workshop garage and office with full bath I am gonna finish as a bedroom and just relocate down there when we have hurricanes.

I used a big loader, can't remember how many yard bucket it was, to clear the roads on my tree farm and I agree I could have dug the hole for the house in a couple hours but like I said I needed to do some backhoeing to and it was cheaper to just rent one and spend more time than rent both for the weekend.

The entire bottom floor above it it a safe place to duck and hide if a hurricane turns at the last minute everyone on my street knows I'd have the back door unlocked and to just let themselves in. This whole project is mostly for fun but then again building the house above was fun to. Peace and no offense taken oh and geez now that I have my glasses and can really see the your question... I live about 30 miles from the Gulf of Mexico and my wife is an invalid and too ill for me to evacuate so I'm well prepared even just with the bottom level being under ground and the bunker itself was a test to see exactly how deep I can go without hitting the ground water so I can build a larger sinpler one that I can just enter through a door at the back of the bottom garage and get my wife inside quick in case we get a tornadoe. I tend to over build things and maybe I planned too much but I'd rather be prepared and never have to use it than get caught off guard.

It would be so cool to have a secret bunker under my house

I've ALWAYS wanted a hidden, underground bunker. As for made me laugh and smile and believe that I could do this as well. It's a very detailed instructable, and I think that with your instructions, I could make a reinforced hole in the ground, too. Unfortunately, I get all the great ideas, but don't have skills with electric/mechanical tools. When I approach my husband with my grand ideas, he looks at me, his eyes glaze over and his jaw goes slack. I'm thinking I might just have to start secretly digging a hole (and I have the perfect spot) and when it's mostly dug out, I can employ his help. I think that it's wonderful that you'll be able to save yourself and your wife if you have to thanks to your bunker.

Love the project, but wish that it was summarized with less detail as to what type of wood your floors are made out of, and more of what you did for THIS project. Also mentioning accidents that happened in your life just distracts from the reading, but its still a GREAT idea.

I was still in La La land when I made this one LOL.

The left side of your head which I crushed deals with talking and I used to obviously really ramble for the first couple years after the wreck not that I don't now...

:.( I always wanted to build things but I never able... never figured out why...

Also watch people work and if you can do it without slowing them up ask questions. That's how I learned most of my skills. I was five when I moved to a new development and there were only ten houses up so I got to spend my summers watching them being built and my first underground refuges were made from digging a hole and rolling logs over it then shoveling the dirt back over them then always had a cool place to hang out in the summers.

The only problem is that I live in the suburbs of a small town in North central Texas, and there isint much land to be bought to build/dig on...

Thanks man!

Soon as I get free time I'll try something...

Never hurts to try. Start simple and small and Instructables has instructions for a zillion things you can build.
