Looked into the patterned concrete 2 years ago when I was doing my drive and to be honest it's nothing compared to block. I got a guy round to give me a quote and he said they were just about to start one in a nearby street, so I could go have a look. Was quite impressed at the time, but in the end I opted for block, infact the exact same as what Lee has posted. When I see it now I know I have made the best choice, absolute night and day in quality of look in my opinion. Like tile effect laminate flooring, looks like tiles from afar, but not so clever up close. Plus, I think you have to put expansion joints in it as well which ruins the look.
Only bother we had was the grass, it didn't seem to grow in patches as you can see, but guy came back round and relayed it with more soil under it and it seems to be all right now.
Just the garage to renew now and I can rest.
