Pavers in FL

Hi,
I am interested in laying some pavers down in my backyard for a patio (16'x8'). Should I layer @4" of gravel first before the paver sand? A gentelman I just spoke with mentioned that most folks in FL just use 2" of sand and no gravel. My concern is shifting pavers. Thanks in advance for any advice...

I assume what you call "paver sand" is really the sand used for the 1" setting bed. the maximum thickness is about 1" and should be uniform. Normally concrete sand is used.

For the surface and interlocking sand, a slightly finer sand is often used (masonry sand) is used and vibrated into the tight joints when the paver surface is evened out with a plate vibrator.

The thickness of the gravel base below the setting bed of sand depends on the stability of the sub base (usually natural soil). For drainage (if desired) of the patio, the surface of the gravel base should be sloped to be able to maintain a uniform 1" setting bed thickness.

Thx...I will definitely use @1-2" of gravel (or marl) prior to laying the base sand. I dont have a plate vibrator so I just plan to sweep masonary sand into the joints, water and repeat for a few weeks. I'll post pics here in a few weeks once completed.

It is better to rent it when you are ready, then use it to compact and smooth base and then to draw the fine sand up and level the surface.

For a small 8x16 patio, you may do everything in one day if you are organized and not too fussy about setting the pavers (just set them quickly and tight). the final vibration is what makes things right.

Some patterns (like angular herring bone and others) take more time.
