Some years ago I decided to replace my poor-condition concrete driveway and after pondering the alternatives, I went for block paving. I did consider patterned concrete - but I've seen so many of these driveways ruined by poor application of the colour/resin coating that I didn't want a similar botch-up.
I still prefer the look of block paving but the constant problem of moss and weeds growing up between the joints is a real pain in the neck.
Anyone got any long-lasting solutions for this problem?
