How can you build a shed into a slope?
My land slopes 18 inches up over 12 feet but I don’t want to raise the whole thing up that high. Is there some kind of pertective material I can use so I can bury the back of it?
I would put in concrete block up to ground level, and then cut the shed walls so it sits neatly on the ground and the blocks. don’t try to put wood underground, even with a tar or whatever protector.
If you do insist on cheating, put roofing tar on the stuff to be against the ground, and then put 3" wide of peastones between the soil and the wood, so water can drain down below the wood. Peastones under the whole structure not a bad idea, either. That may work for some time.

A couple of thoughts. Either excavate some additional space behind the structure and utilize a french drain with plenty of gravel or you could pour a concrete pony wall that should receive a membrane waterproofer, gravel and a french drain. The pony wall should be stepped down to match the slope of the existing grade.
If you go for the concrete pony wall you will need to let it cure and then use a below grade primer and a waterproofing membrane. It also helps to use a drain board to keep rocks from compromising the waterproofing while allowing water to flow freely away from the wall.

split the difference…. set some blocks down at the 9 inch mark(1/2 the 18 ) at the rear end then build it forward onto 9 inch block that was you got all problems solved..if 9 inches aint to high
