What would be the advantage of a layer of sand? How thick a layer do you
have in mind?

If I lay the brick directly on the concrete, albeit with hairline cracks,
would that not be more stable and less apt to generate weeds?

Thanks

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 suggest a bed of sand under the brick.
