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.

I know that you don't have much space, but try to get a layer of coarse
sand between the concrete and the pavers. In fact, concrete sand
pavers is how the pro's do paver driveways.
