Four inches of compressed base rock (3/4-). Then 1 inch of sand. Use a solid edging like lumber or Snap Edge. Set pavers. Then compress pavers into sand, fill gaps with fine sand, then seal with quality sealer like Sure Bond.
I want to lay down some decorative brick/pavestone in my former flowerbed.
How is best way to get solid foundation before putting down this brick?
Usually that means digging out at least 4 inches + the thickness of the paver of soil fill in 3½ inches with compacted crushed gravel and about an ½ inch of sand base.
Couple inches of crushed rock/gravel, then an inch of sand... Compact and level well. Lay the stones and sweep sand over to fill in the gaps.
Try Google.. you should get lots of hits.
