I didn't mean to indicate that Racedeck is a **** product, which your floor clearly shows can be a great look. I was refering to the broken concrete with asphalt subbase that he would be trying to hide. I bet your subase is solid. If you had laid it on a flexible subase it wouldn't look so good.
I misunderstood you then. I assumed since the majority of the thread was talking about putting plastic tiles over asphalt that your "**** on ****" comment referred to that.
I agree it would be ideal to rip out the old asphalt/concrete and pour new concrete, but that is very expensive and time consuming. It sounds like that was out of the original poster's budget, as it was with mine in my shop.
I am very happy with the decision to use RaceDeck. My floor is in very rough condition. The asphalt was there to cover up concretely that was cracked badly. There were several large potholes in the asphalt, and the more I would work on it, the more it would get torn up. The concrete area of the shop was in better condition, but there were several large cracks in it since the entire 2000 sq ft slab only had 1 relief cut down the center.
While you will get the best results putting RaceDeck on a nice smooth floor, you can definitely put it down on an uneven floor. The tile interlock strongly, it is difficult to get them apart. There are a couple areas in my floor where there is nearly a 1" gap between the bottom of the tile and floor. They flex and conform to the floor when there is significant weight put on it, but it doesn't come close to snapping apart. The entire floor floats, so if your floor moves underneath the RaceDeck will just flex to conform to it. Before we put down the floor we used 2-3 bags of floor leveler (for the entire 2600 sq ft we did) and just smoothed out the worst areas as best as we could.
I attached some "before" pictures of my floor. The floor was actually in much worse condition than the pictures make it look.
