I dug out 7 inches or more, laid 3/4 inch stone 3 to 4 inches high. Plate compactor over it all. Threw a little sand on top and let it all settle in so rocks were no longer 'active', everything appears tight. Little water. Sat for a few days. I then put down inch and half srips and threw sand on and graded it over the inch and half boards, pretty level, did need some slope for run off. I did install one inch and a half paver and it was a bit low, not level with existing walk. But I know other parts might need a shade more sand so I would be at 1 1/2 some places and it might need 2.5 possibly 3 in other places. So should I pull up sand as best I can, lay more crushed stone then sand over that? Lay more sand? (Read enough that no more then 2 inches)?? The pavers are 16 x 16. Advice/recommendations.
