New Paver Patio Installation
I assume you are laying real concrete pavers (lass than 10" maximum dimension) and not "stepping stones".
The proper way to build a paver surface (sidewalk, patio, driveway, street or airport taxiway) is to have the compacted road base follow the slope, grade or shape desired.
After that, a 1" layer of a sand setting bed (NEVER compacted !!!) is spread on top of the compacted base. You level the sand with screed guides that can be wood, pipe or your patio edge restraint. Cut a long, straight 2x4 to use as a screed and you can cut notches at each end, so the bottom of the screed is at the proper amount below the screed guides.
If the patio is too wide for the available screed, you can set a temporary screed guide in the center. Remove the temporary guide and fill with loose sand.
When laying pavers, you work on the pavers previously laid. Lay the pavers with tight joints and good pavers have spacers cast into the side of the pavers. You can awalys re-screed the loose sand setting bed if it gets disturbed.
After laying the pavers in the sand setting bed, you spread sand over the top and vibrate level so you have a smooth surface and sand vibrated up and down into the joints.
You can go to the Interlocking Comcrete Paver Institute (ICPI) site for good information - icpi.org is probably the address. - Any good paver supplier should have instructions available.
