Sorry guys, I don't do hardscape installations with clients and I have a few questions I was hoping you could help me with (this project is for my personal residence.) I am installing two patios in my backyard, first one is 11x21, second one is 8x8. I am just about ready to lay the base layer (1" crushed limestone), and have a few questions. The first patio is bordered half with a mortared rock retaining wall and half by nothing (will just have a small bed here.) The second patio is not bordered by anything at all. So, when laying the base layer, do I need to support is with something (say lay down like a frame of 2x4's) or do I simply lay it where I need it and then compact it. I would imagine it needs to be framed somehow. Secondly, this is just for reassurance, I am laying down 4" of crushed limestone and then 1" coarse sand, then the pavers. Sound right? Also, how much does the 1" limestone compact? Looking for a 4" compacted layer, how much needs to be layed on before compaction? Thanks alot guys!
