Very interesting logistics in building a tire wall! With the cardboard, it will eventually degrade, this doesn't cause problems in the long run? Since the dirt would eventually fall through the bottom? Is there a lot of dirt that gets put in between tires not just inside of them?
Ah, you're already a step further, @farmstead, hehehe, in the realm of packout. And yes, you're absolutely right: in the back the whole wall leans onto the berm of dirt, and in the front the spaces between are packed out with concrete (containing cans, bottles, and other garbage). Once it's covered, you won't even see the tires.
And yes, the cardboard will degrade eventually, but by that time the sheer mass of the wall will keep itself together. Plus, where would the dirt go, if there is more of it all around the tire? So no worries there. But thanks for your great questions. Makes me realize how much more there is that I haven't even touched upon...
Hahah you're welcome! I guess! Haha I Don't meant to trudge ahead in your storyline! Haha, at least I give you fuel for your fire! Hahah.
Ah that makes sense now, that you say the front is contained... ish. With concrete and other materials. This sort of wall building is a great way to "hide"/"reuse" those materials that may not always get a re-use, like the garbage you mention.
