Hey folks, A little background on me: Up until now, I've only been doing basic landscaping work (planting shrubs/trees, lawn cutting...) and I do it on the side mainly for friends and friends of friends. But I've had a few people ask me about doing paver patios. So, rather than experiment on someone else, I've decided to replace my pool patio since that needed to be done anyway (major leak in the pipes that had to be repaired and concrete was messed up). Project: 500 sq feet of Unilock Brussels Block. Compacted fill, then 6" of compacted 3/4" Crusher Run, 1" - 1 1/2" sand, then the blocks, then polymeric sand for the joints. Now for the questions: 1) I know to pitch it away from the pool at roughly 1" for every 4'. However, how important is it that the sub grade soil is pitched in the same manner as the base above it? Do I need to get the sub grade pitch perfect as well? 2) Since I only do this on the weekends, after I compact the base, is it ok if the compacted base sits uncovered for a week or two? Or would I have to compact it again if I did? If it rained in this time period, would that have an effect on the answer? 3) There are a few small areas that I want stone, but I don't want to put base. These are above the connections to the pool. I want to have easy access to them in case of pool leaks. If I were to put sand and soil there and compact it really well, are these areas pretty much guaranteed to fail? I don't mind resetting them each year, but if they would shift 3 times a season, that would not be fun. They would be about 2' X 2' each. 4) What are details for the expansion joint in between the coping and the rest of the patio? i.e. what size, material, anything else I should know? Thanks so much everyone! Really sorry for all the questions but I truly appreciate the help!
