Walter,

You should have no problem doing this. I just finished a patio job over
Memorial Day weekend. I put 1-1/2" pavestones on top of an existing
concrete patio. I couldn't use the 2-3/8" thick pavestones because it
would put the patio too close to the level of my door threshold. I put
a 1" deep bed of sand on top of the patio and then laid the pavestone
brick on top of the sand. I then used a plate vibrator to tamp the
pavestones down and then swept sand into the cracks.

Don't just lay the brick on the concrete. The imperfections in the
concrete and brick will cause them "rock" and/or break when they are
walked on.

I actually made my patio larger than the existing concrete. I had to
excavate down about 4 to 6" where the concrete patio didn't cover and
then filled in with decomposed (crushed) granite. The granite was
tamped down tight and made level with the existing concrete patio.

Here are pictures of my project from start to finish:

I have an outdoor patio 11x40. The concrete slab has some 1/32" heat
expansion cracks,
unsightly but not really structural.

To improve the appearance I would like to put a layer of split pavers
(bricks, 1 1/4" thick) on top
of the concrete slab, without gluing them down and without joining the
bricks by mortar or grout. By abutting the bricks it should not matter if
the small
cracks work a little in the future. The split pavers will be enclosed by
walls on all sides. Any tiny voids between the bricks will be filled in with
brushed sand.

I do not have vertical space for standard pavers (thresholds).

Is this feasible? Thank you for any input.
