I've just bought this for a neighbour's driveway. I chose it because a car will drive over it daily. The company's official info. sheet is attached. But the Wickes info. says " not suitable for anything heavier than pedestrian traffic". Can you see why I'm confused? I know that Wickes used to sell the first one in the list so I suspect they haven't amended their sheet. If you look on the Wickes website you'll see that the 5 tonne is the only one they now sell of this type and my invoice definitely says 5t so if the car disappears down the hole who will be to blame?
