The guys around here use Smurf tube in concrete. It is more forgiving if your chipped out trench is not straight.

PVC is fine. Are you using the Carlon PVC boxes??

We have had "0" problems.

This is just a preference reply, but Hubbel pvc floor boxes are imho a tad more forgiving to trim out because of the way the trim ring is designed. They use 4 clips to hold the pvc trim out plate secure rather than just glue held in place, and therefore seem to me to be much more securely fastened that way.
