When I began pondering critically about beginning this I knew I needed to do a number of easy checks first that might value me a bundle if I needed to rent an Engineer and do them even earlier than I utilized for a allow.

They’d wish to know the various kinds of soils, how thick every seam was and most significantly I needed to understand how far down the water desk is.

I reside in Florida and usually in the event you dig a gap a number of ft down you will hit water however I am within the Panhandle of Florida so we even have some hills right here. The lot slopes to the lake sufficient I used to be in a position to dig a backside stage into the hill giving me a fairly protected place to cover if we get a nasty hurricane. The home is extraordinarily bolstered and all of the partitions are shear partitions which means at the least one facet has plywood glued and nailed each 4 inches, together with a second layer on the within of the outer partitions which additionally went a protracted technique to soundproofing the place. I’ve extra anchors than required and threaded rod going from the footers to the trusses together with the inside partitions.

The molding work on the ceiling of the good room is definitely tied into the roof trusses and the flooring are all three/four plywood tongue and groove and glued and nailed plywood each 4 inches for a subfloor. It’s lined by three/four by 2 1/four Oak tongue and groove operating perpendicular to the ground joists. The Kitchen, Halls and Bathrooms I tiled however the bulk of the home has the Oak making a really stout roof for the underside stage.

My workshop additionally has plywood ceilings in order that half is particularly strengthened to the purpose of a tornadoes shredded the highest two flooring you would be protected huddling beneath the work benches.

I are inclined to ramble as a result of I crushed my head three years in the past in an accident so again to the meant matter of the way to dig a gap beneath a home and never have it fall on me.

My main technique was that I felt I may safely dig alongside facet of a footer and pour a 2 foot excessive concrete wall as long as I did it in phases the perimeters wouldn’t collapse for a number of day, particularly if I misted it with water from the hose. I drove rebar a few foot into the sand or clay and left the remaining protruding the highest so the ultimate backside to high pour would bind all the things collectively. I additionally after the concrete had dried and I had the varieties moved down one other 2 ft I might use a small spade to search out the underside of the earlier rebar, and utilizing a chunk of pipe for leverage I might bend it into the world of the brand new pour at a 45 after which bind it to the rebar for the subsequent pour. The finish result’s a really solidly secured concrete wall 10 or 12 ft excessive formed like an inverted wedge to discourage it from sinking into mushy floor. Also I made a decision to solely do 10 or 15 ft at a time however by no means the size of a complete wall in a single shot so I did not have the perimeters blowout like in a mine accident.

I spent 7 years constructing the home I do not wish to trigger it to break down and the spouse would by no means let me hear the top of it.

I then figured I may preserve repeating the method primarily forming a really tall staircase and once I had sufficient head room I might pour a remaining layer eight or 10 ft excessive to tie all of it in. Billy down on the constructing division would have a match if I advised him I needed to do that and I might want an actual engineer to place their stamp of approval on it and it isn’t the kind of job you can begin and stroll away from midway carried out if one thing comes up, so that is an excessive amount of for me to do as a solo undertaking and I;m not truly Licensed Florida Contractor.

I did determine I ought to do a check shaft to see if it truly labored and get a file of what was down there and I might positively must know the water desk top and the considered having to assemble a mini drill rig in a crawlspace appeared fairly costly however by staring lengthy and laborious at it for a time and a day, I made a decision I may dig a shaft by hand proper subsequent to the entry port and canopy the steps with a comfortable piece of plywood then shovel it out the port onto the steps then into wheel barrows and dump it out again.

How laborious can that be?

I had a restricted finances however I do personal a mortar mixer and had an excellent stockpile of rebar and three inch pvc pipe left over from one thing I can not recall and a few lumber I might used already for concrete varieties and sure there’s a Plus facet to OCD particularly you probably have the room to retailer it till you want it.

I selected to not point out to the spouse what I used to be planning principally as a result of she would have mentioned no however I had nearly used up all my financial savings ending the home however I nonetheless had my emergency $1000 so I did some math and bargained for a cheaper price on 80 pound sacks of Redi-Mix if I purchased 6 pallets and so I snuck a have a look at the spouse’s calendar to see her subsequent medical doctors appointment and her caregiver would drive her so I arrange the ship for when she was gone and had an area cleared within the backside storage that I may retailer all of this, and had some items of pipe available to stroll like an Egyptian and transfer the 3000 pound pallets to the far again of the storage by rolling then after which utilizing the subsequent pallet to roll the primary to the again till all six could be safely hidden inside.

The spouse was operating late although and so they confirmed up simply as she was leaving…

Fate Strikes Again however my spouse is aware of I used to be nonetheless not fairly proper within the head in reality she’d say I used to be like that even earlier than hitting my head and is used to me simply leaping up within the morning to begin engaged on one thing and I did in spite of everything construct her a home and miraculously she did not ever actually ask me what the cement was for.

Once I had the cement I thought of varieties and I made a decision if I’m to do that and make a 2500 sq. foot bunker I want the varieties to be modular so I may preserve reusing them time and again.

I made a decision on a number of fundamental sizes, 2′ by eight’,2′ by 6′, 2′ by four’, three’ by four’, and I made them with the braces in every dimension an identical so once I wanted to make 50 of those I may drill across the perimeters in a normal sample so I may simply bolt these collectively, pour the concrete, then unbolt them the subsequent day and transfer on. Trial and error taught me that staple gunning a easy layer of 6 mill plastic makes for a a lot smoother wall than plain plywood and also you simply want to switch it each few pours.

With the varieties made and the 6 yards of concrete safely hidden and lined with a tarp simply to be protected I began digging subsequent to the entry port so I may get some standing room. The first 5 ft of soil is sand I consider known as Orange Ruffie however I will must examine my soil survey of Walton county to make certain.

Regardless sand is fairly simple to shovel though the very high layer was had dried out fairly solidly and had some clay blended in I needed to spray it with the hose to melt it up. You truly must preserve the sand moist or the perimeters will collapse rapidly and I made some extent of misting the bottom earlier than I give up engaged on it for the day.

I made this roughly 7 by 7 since as I went deep it could get narrower and I used to be about 18 inches between two columns supporting the beams so this was a great place to check. On the primary 2 foot pour I additionally poured and shaped a beam between the columns with loads of heavy angle iron lower to suit tight between the columns.

The I began getting the hits from The Office of Homeland Security which I figured was simply because so my of my site visitors comes from Walter Reed Hospital and the remaining from our troops overseas.

Then the cable firm knocked on my door and mentioned some magic piece of apparatus allow them to find the supply as by some means coming the crawlspace beneath the home and so they wanted entry beneath there to examine for issues…
