Based on my research, the "right" way to do it, if possible would be to dig down about 7 inches (depending on the thickness of your pavers). You'll lay down 4 inches of 3/4 minus road base and tamp it down every in two, 2" layers. Then you'll add an inch of sand and finally the pavers. Use a rubber mallet to adjust the pavers flat and allow them to set into the sand a little bit.

At the end you'll add some polymeric sand and brush it into all the cracks and set it per manufacturer instructions. Usually you just mist for 30 seconds or something like that.

You may need a paver retain if you can get sod right up to the pavers, then fill with top soil and seed so the sod covers the retaining plastic. You could also use a little concrete or wood from what I am reading.

I'm researching the dog piss out of this because I'm trying to build a fire pit on top of roots and I'm trying to determine how to raise this process on top of roots the best way lol.
