I can't advise on artificial grass as I don't do this type of work but regarding the turf you would need a minimum of 4 inch top soil between the membrane and turf for it to establish and root.. You may still get weeds growing through the turf but ask g as you keep mowing they will soon die off or you can apply a weed and feed but only a few months down the line when grass is established. It really isn't as People want you to think Just make sure the soil is level as possible compacted then lightly raked, roll out the turf and slightly overlap the edges and water well grass is hardy and will root anywhere
