I want to build a garage. My site is about four feet lower than the driveway. I will build stem walls on footings to start that will reach the elevation of the existing drive and will totally enclose the new slab. I read on this site that pouring a slab on top of 5/8 crushed rock with no additional compaction of the crushed rock is an acceptable method of slab construction. I would like to spend the extra money on the crushed rock and then not have to worry about meeting any other compaction requirements if possible. I would like verification that this is an acceptable method of slab construction. Thank you for any help or other ideas or suggestions about my project. Regards, Ralph
