[QUOTE="davek, post: 2201717, member: 519"] Fiberglass shelters in ground have concrete poured over them to keep them from being pushed out of the ground by hydrostatic pressure (water table). If I recall correctly they put about 9 tons of concrete on mine, it's approximately an 8 ft. diameter sphere. I do wonder about the fiberglass door though, but at least my wireless Internet connection works down there - unless something very bad happens. [/QUOTE]
