my brother installed two welded together and installed them underground not a weekend warrior project we are veteran underground contractors .that bring said they work great total out of pocket cost was $13000 not including our labor or equip. we had what we needed. this is aprox. one third of what my " root cellar" cost going through normal const. channels with this having more sq footage . one plus is if you have your ducks in a row they can go in over a 4 day weekend his has been in over 3 years with plumb bobs at six points with no deflection noted . they were basically used as a shell for the other const mats. enjoy the forum glad to finally contribute somthing that is in my wheelhouse .mark

I dont have any pictures maybe my sisterinlaw has some my brother and i were more concerened with getting it covered up
we had it in and covered up in four days with 3 to 5 men .i will run a time line with what we did hope that helps . day one started my nephew welding the containers together my brother and i started digging for the containers . warning when excavting any thing over 5' deep it should be shored or sloped back CAVEINS KILL that being said we went 12' deep we then installed 4" leach line and then daylighted it out we then laid down 6" of 1" rock over the hole base . after welding containers together but before welding doors shut you install your cribbing 4' up on the wall we used aluminum trench shoring the whole length 40' after this weld doors shut we then welded in two 12" vent pipes then coated it with two coats of bitchmastic pipe coating we then set the container on the rock and then covered it with 2 sheets of 6 mill poly we then poured a set of concrete pads every 10' we then set a 12" sdr35 pvc pipe in each pad concrete was 5 sack then finished day tieing steel for columns end day 1 14hrs . day 2 poured 40 yrds 2 sack slurry up 1/2 way on walls be sure to use excavtor to hold down container or it will float "voice of experence" spent rest of day setting steel in columns . day 3 poured rest of slurry another 47 yds then finished tieing steel and bond beam for roof we then welded four 3/4 " bolts on all corners and then ran #6 stranded past the slab for a sacrifical anode "redundant rust protection" last min decension we then poured the slab end of day 3 14 hour. day 4 covered slab lightly with dirt and let concrete cure next project was to cut door in with plasma cutter i wont go into detail about that make sure that you are ventelating the container DO NOT USE A OXY/ACTEL torch you will blow yourself into next week once inside with resperator/ fansblowing and a confined space blower hooked to your 12" vent pipe remove your shoreing from from 1st container then cut four slots aprox.2' wide evenly spaced be careful plasma cutters will cut thru your shores 1200 apeice . then take four pieces of 4" scd 40 steel pipe and weld them good set your 6 plumb bobs and take several mesurments up/down across end to end record these then cut out the center walls rechecking your mesurments as you go at this point once the walls are out you have a lot of grinding/painting to do depending on how nice you want it . you can use a round duct fan in your inlet pipe for fresh air. hope this helps mark
