I got my driveway done with imprinted cobble effect October 2005 and it now does not look great. The colour has faded and the surface is starting to flake in certain areas. Basically I got a poor quality job done. Done correctly I think it looks impressive but please ensure you get a reputable contractor who has plenty of previous customers you can check out. It is a specialised job and there are a lot of cowboys out there trying their hands at it getting it a bad reputation, unfortuneately looks like I got one. Paid 5000 euro not sure what size of my drive is , approx. 100 sq m.
