I aint digging no hole for stress relief...but i do have a project under way.
I am essentially the second owner of a house built in 1958. The former owner was completely paranoid about the bomb, and had a 10 foot high, 45 feet in diameter modular concrete bomb shelter buried 15 feet under the soil near the front door of the house. It was orriginally rated at resisting an over pressure from a blast up to 3,600 pounds per square inch.
Im in the process of moderdnizing it. ill send pictures when i finish.
:shock:
