If you were to buy a kiddie pool, you could fill it up to a marked level with water, then take full buckets of water out being careful to count the number. Then you could take the weight of the bucket of your typical fill material (wet sand?) considering how much water would be there during the "full of water" portion of the cycle, and do the math to calculate the final weight. It's amazing how heavy wet dirt is! Since I'm normally accused by Hubby of under-engineering projects I build, I think I'll encourage other permies to speak up.
If I'm going to try all this, I'd like opinions re: whether soil would provide enough support to keep the plastic in shape, and how to know what these beds would weigh and how heavily the platforms need to be built.
Jay Angler wrote:To me, what you're saying is that you think the reason the plastic has warped is because of the "slump" and you use "slump" to refer to changes in the shape of the bottom of the bed due to lack of contoured support. That implies that simply providing better support for the top edge won't be enough to cure your problem.
Jay Angler wrote:I have to admit looking at your pictures that it appears that the top section of the IBC is not particularly well supported. It totally respect your reticence not to disturb all the plants, but the plastic may not easily cooperate about returning to its original shape if it's been left for a long time deformed. I would use the heat of the sun to help when pushing it back and look carefully for cracking. It would be a shame to go to a lot of work fixing it and then have it spring a leak, although if it's final position is over top of the lower tank portion, a bit of a drip may not be a deal-breaker.

Do you have access to a tractor? One with forks? Would it be strong enough to lift the bed off the tank and set it on a skid?

I'm seriously jealous. Here they're more like $150 *if* you can even find one! Good score, and it will be interesting seeing what all you do with everything you now have to work with.
There's a place outside of town that sells IBC totes for $50.
