thin cement slabs crack so easy if the bed they're put on isn't really compacted right. are they reinforced at all?
we made some decorative edges of slabs 30 inches by 16 or 18 inches, didn't put any rebar in them, they snap very easily. i've broken two of them already this year and i was being careful.
In my past I worked for a city and coordinated with developers who were building new sub-divisions. One of the subdivisions, we made them put those pavers in for an access road to an area that was owned by the City and was not going to be connected to a paved road. The access was for firetrucks to get to the pond for water in case of emergency and for city employees to be able to go in and control the invasive weeds.
