I'm installing a 15 X 37 paver patio and just tamped 4" of 2A modified (which unfortunately had more clean drainage stone [2B] in it than usual). Because of the abundance of 2B in it I tamped the living daylights out of it. I'm worried about the sand bed on top of it. The questions I have are: 1. Should I cover it with another finer stone dust and tamp again or will it be a good enough base as is. 2. Because of the relatively large stones in the base it has been a pain to level. I got it pretty darned close but it isn't perfect and has small variations up to a 1/4" here and there in peaks and valleys. Is that good enough for the sand base to take care of the rest or will the pavers show the variation when I tamp them? 3. I heard one technique to counter this is tamp the sand first before laying the pavers. Then tamp again. Does this sound plausible? ....not to me. and finally.... 4. The patio is mostly rectangular with no right angles. I'm installing a circle kit at one end. Should I install that first then work toward it, or install the "I" pattern first and install the circle when I get close to it. I know this is a lot. As you've probably surmised I am a DIYer. This project is huge with three stair cases, two landings and five foot retaining walls with a future inground pool at the bottom. I just want to make sure my patio looks as good as the rest has come out. Thanks so much for any help. I'll post pix when done.
