Normal is 4" concrete with a wire mesh over 2" of sand over a 6 mil visqueen membrane over 2" of sand.

Recently, some have started using a fibreglass mesh in the concrete mix instead of the wire mesh. This seems to work better since it is uniformly spread thruout the concrete and unlike the wire mesh it won't rust over time. Check with your local redimix company.
