Storm
There are several types of homemade storm shelters that are available for the do-it-yourself homeowner. Some of them are simpler to construct than others, and some of them can be made at minimal cost. Although homemade storm shelters may require a bit more work and time than prefabricated storm shelters, they can be quite rewarding once they are built. Most homemade shelters can be constructed in one to two days, depending on the size and type. Does this Spark an idea?
Storm Shelter
The first and most sophisticated type of homemade storm shelter is the concrete block storm shelter. Usually made from 8-inch concrete blocks, you can outfit it with ventilation and drainage systems to make it comfortable and functional. You will construct this type of shelter on top of 12-inch-thick footers that are 16 inches wide. It is important to fit the footers with rebar both vertically and horizontally. Insert the vertical rebar into the wet footer every 3 feet; it will extend into the block wall for support. Lay the horizontal rebar flat into the footer ditch before pouring the footer. The rebar will add strength to the poured and cured footer and will help hold up the shelter walls. The wall heights of the shelter should be around 7 feet, but make sure that you have enough space inside for head clearance. Once you have laid the block walls on top of the footers--making sure that the rebar runs vertically through the blocks' core--pour the block cells solid with concrete to help strengthen the walls. The roof of the shelter can extend above dirt level by no more than 12 to 24 inches. Make sure that you pour concrete for the roof and reinforce it with rebar. The roof--flat and 6 to 8 inches thick--will prevent any intrusion from trees or heavy objects.
Another option for a storm shelter is to install a large concrete drainpipe or metal boxcar underground. You can install ventilation and drainage in the same way as the concrete block storm shelter, and this option may be slightly cheaper. Be creative when selecting materials that are readily available. Plastic storm drains or any large container will do; the most important thing to remember is that they should be strong enough to hold the weight of surrounding dirt.
