I did some searching, found information on shipping container from 2007; however, this video dated 23 Dec 2009, Final attempt to recording the building of an underground shelter using a 20ft shipping container.
I would install one; but, lot size too small, HOA and finally the wife!
Final attempt to record building of an underground shelter using a 20 ft. shipping container. For those wondering why I didn't simply pile dirt over it without pouring a concrete cap first..... These containers are mostly sheet metal. Heavy duty as it is, the roof and sides will push inwards from the weight. Eventually the metal will rust through and you'll be buried alive. My way will insure it is still there a few hundred years from now. Problem is, you'd better keep an eye on your sump pump. If it goes bad or loses power, you'll go in one day and find it the whole thing flooded. A surface alarm letting you know the water level is above where it should be isn't a bad idea. Putting the sump pump on a UPS is also a good thing.
Some of the authors comments:
Since there is no down-hill natural drainage, I have to solely depend on the sump pump to prevent flooding. If I could have budgeted it I would have cut a French drain through the bottom and down the hill, but it would have added an additional $7K to do. After a good rain, without the pump the entire cavity would fill with water. Since the creation of this video, I installed a backup pump and an alarm that will sound inside the home should the second pump come on.
All power is tied through a 50A UPS in case of power failure. It can handle the pumps and lights for up to 10 hours. As for sinkage, there isn't any. The bottom of the hole is solid limestone with 6 inches of peat gravel between it and the bottom of the container. The peat gravel allows all the water to move to the reservoirs that contain the sump pumps. On another note.... We have started experiencing 80F days and the temp inside seems to stay at 55. Good for wine making.
