How about an oiled cloth tarp?
A cloth tarp made of canvas or similar, soaked in a drying oil such as linseed and used as the waterproof outer barrier. I've done a few searches...Has this been discussed before?
Ideally you'd have cotton or flax or hemp growing on the land for your cloth source, and then walnut or linseed or similar
growing onsite for the oil source...
How about wax?
The real question here is how long can an oiled canvas tarp last underground--anyone? Can it be made to last a bit longer? How long would it need to last in order to make it worth while? Let's say it lasted ten years. Hell yeah, your house just lasted ten years. Cool, right? And then really....I wonder if you new the tarp was reaching the end of it's life (ten hypothetical years) you just do some careful digging, pull out both sheets and relay with soil layers. Maybe it would even be feasible to just replace the topmost layer of tarp, once every xxx years. Or even, watchout I'm crazy, what if you just left the old tarps in place, merely added a new layer of waxed tarp, plus a few inches of new soil, once ever xxx years.?
