If you're concerned about being bombed, but don't have the many thousands of dollars required to buy and install a commercially available bomb shelter, you may have to settle for the home-made kind. A cheap bomb shelter won't protect you from a direct hit by a 200 kiloton warhead, but it can keep you alive during radiation scares.

Skill level:

Things you need

  • piece of 12 foot diameter steel culvert, 20 feet long
  • piece of 2 foot diameter steel culvert, 6 feet long
  • 2 pieces of 4 inch diameter PVC pipe, 6 feet long
  • 4 90 degree PVC elbows joints, 4 inch diameter
  • 2 air filters
  • 100 foot roll of elephant trunk pipe
  • breeze blocks
  • mortar
  • backhoe
  • shovels
  • cutting torch
  • welder
  • interior furnishings
  • 2 foot diameter bomb proof hatch

  1. 1

    Dig a hole in your back yard that is deep enough to put the culvert into with three or four feet of soil on top of it.

  2. 2

    Install the elephant trunk pipe around the perimeter of the hole. This is black corrugated plastic pipe that is bendable and used for drainage. Dig a trench in a direction that the ground drops away and run the elephant trunk down it. This will help water to be drained away from your bomb shelter.

  3. 3

    Roll the steel culvert into the hole with the help of a large number of friends.

  4. 4

    Cut holes into the top of the culvert using the cutting torch. Cut a 2 foot diameter round hole in the centre and a 4 inch diameter hole at each end.

  5. 5

    Weld the 2 foot diameter culvert to the 2 foot diameter hole so that the piece of 2 foot diameter culvert is vertical and protruding above ground level. This will be your entryway. Attach the two pieces of PVC pipe to the two 4 inch diameter holes using 100 per cent silicone waterproof caulking. Attach two 90 degree elbows to the top of each pipe to create a 180 degree curve at the top so the opening is facing down to keep out rainwater. Install air filters over the ends of these pipes.

  6. 6

    Move any possessions or objects that you want in the bomb shelter that won't fit through the 2 foot entryway into the bomb shelter through one of the open ends of the 12 foot diameter culvert.

  7. 7

    Build walls at each end of the 12 foot diameter culvert using the breeze blocks and the mortar.

  8. 8

    Backfill the hole with soil until it is slightly mounded above ground level, leaving only the end of the 2 foot diameter culvert and the two 4 inch diameter PVC pipes protruding. The steel culvert provides walls for your shelter, but it is the tons of soil that actually protect you from a bomb blast.

  9. 9

    Install a bomb proof hatch over the top of the 2 foot diameter culvert.
