The details (I have to check my phone, she texted it all to me):
- Concrete for foundation poured 11/17/09, and they started packing dirt about 5 days later
- 539 tires
- 67 tons/130 cubic yards of dirt, around 90 of which got sledgehammered into tires. the left over dirt will get spread inside the perimeter to raise it to a 4" slab
- Approximately 250-300 pounds of dirt per tire. That was about three wheelbarrows full of dirt per tire, until after the third tier was complete and the fourth tier was too high. From then on, they used kitty litter buckets, and most tires used about eight kitty litter buckets full of dirt
- Now they are going to "slap some concrete mixed with dirt in the v's between the tires utilizing three soda cans to take up space to further the energy efficiency"
- Last tire packed 4/12/11
