I have a lot of rock debris and surface shale that I've raked out of my lot prior to seeding. Since there is no landfill here that I can take it too, I had a brainstorm to make a two foot high patio and dumb all this rock as fill, then cover with either pavers or concrete. Will this work? I'm sure the right way to do this is with compacted gravel of a certain size, etc., but the whole point here is to make a place to dump this shale on my lot where noone can see it. Any thoughts? I figure if I use pavers, I can level it off and set them in sand or mortar. Maybe a some kind of interlocking paver would help? I am a novice homeowner , not a pro, so all tips are appreciated.
