We bought a place in the Ozarks which, thankfully, has no building codes with the express purpose of building an earthbag shelter. While the county has no restriction, the electric company does. Before they will run the line, we must have a concrete foundation for at least a 1000 sq. foot house in. My idea is to build a psuedo foundation of block with very weak mortar so we can break it apart and use the blocks for my smokehouse. Any recipes?
earthbag - quick and reusable. Tell them the foundation is buried under the bag walls.
That would be great, but we aren't building a 1000 square foot house. It irritates me to be told I have to have a bigger house than I need.
Thought about the cob, it might look enough like mortar.........
Can you tell them you need to have power run to the shed so you have something while you're building the house?
Oh they'll do that........for $1800 per pole....x 6 poles. With the 1000 sqft foundation it's $450 a pole...first three poles free. Oh, and we don't have any sheds..
So, something you can do is to get plastic (I was going to say OSB, but I think the plastic will be cheaper) and tape enough together to form a square 32ft by 32 ft. Level out the ground you're going to be building on, lay the plastic down, and use the blocks to hold it down. Line up the blocks like they're forming a wall (this may affect the size of your plastic, but as long as it is at least 32ftx32ft, you'll be fine.)
Next, mix up enough thin concrete to cover the plastic to about 1/4 inch. Let it harden, and you've got your 1,000sq. ft. foundation. If push comes to shove, you can cover your "foundation" with a tarp "to protect it from the weather and let it cure". After the power company's gone, you can cut up the concrete to use for a rubble trench or whatever your next building project will require.
I'm assuming you're talking about those concrete blocks with the two big holes in them
Ahhh, I was imagining using the actual broken mortar pieces as blocks, like urbanite. Now it makes more sense.
Again, going from what I've read about what not to do, you should be able to get crumbly mortar either by using too much sand in the mix, or not enough water.
instead of portland cement will give you short term adhesion and pliability when it comes to using a trowel. When it comes time for deconstruction, the blocks should readily pop apart with blows from a rubber mallet. Good Luck!
