pavers on concrete slab?

continuation of a previous question,
can I use interlocking pavers over a concrete
slab? I plan to lay down a bed of sand since the slab is not level.

another question is: How do I keep the boarder pavers in place? unlike laying them in the dirt, I cannot use various plastic edgers.

thanks, I found the answer to my question in the FAQ of the mfg of the paver I'm using, (nicolock) and they say it's ok to use over cement;

Cement the edge pavers in place at the right height, then install the pavers on 1" to 1 1/2" of sand and Yes you can install pavers over concrete even asphalt as long as the base is stable.

Pavers over slab

I am planning a similar project. on a long skinny slab at the rear of my house. I can't seem to find the information on prepping a cement slab for pavers. Does the slab have to be sanded before the pavers are installed?

pavers on concrete slab?

The biggest problem with putting interlocking pavers over something like concrete or asphalt is getting the water to drain out of the sand setting bed since it has no place to go.

If the water is trapped the pavers can "float" and not have good support. This can lead to an irregular surface. The thinner the sand setting bed, the more stability.

Normally, in the ideal world, the base concrete or well compacted base is graded to be parallel to the finished grade which will allow a uniform thin setting bed of 1" (maximum).

If it just for just a patio you might get away with it, but it would not pass for a driveway, street or heavier loads that require the water to be drained away in some manner.
