No these are like 2'x2' plastic squares within the 2'x2' square there are something like 2"x2" cut outs. You put them in the ground level to the dirt and the existing grass grows through them. Since you level them you could walk on the grass and not even realize they are there. You could drive over them while it's raining and you won't do any damage to the turf. I've seem commercials for them and I think i've even seen them in an old Turf mag ad but now can't find them.
