I've never heard of putting AstroTurf onto a concrete base.
It's normally type 1 sub base whacker plated down until level, then grano dust on top that gets brushed then whacked and swept then whacked again until it's billiard table smooth.
Yeah if starting from dirt, but fucked if I'm smashing up and carrying out more concrete through my house (no access). A cursory Google suggest it's ok, but obviously needs to drain hence the screed and Ako.
