MORE FAMILY SHELTERS
In selecting shielding material for any shelter, sand or earth can be substituted for concrete or brick, but for every inch of solid masonry you need an inch and a half of sand or earth. Adding shielding material to a shelter will improve the protection offered by the shelter, but it also may increase the cost of the shelter.
This sand-filled lean-to basement shelter will accommodate three persons. The house itself gives partial shielding. Sandbags are used to block the end of the shelter.
This backyard plywood shelter can be built partially above ground and mounded over with earth, or be built totally below ground level. A gravel drain under the shelter and a ditch outside help keep it dry. The family blocks the entrance with sandbags after entering the shelter.
