Hi - looking at the 'new' geogrid with pebbles option for a driveway - similar to either the Cirtex surepave or Natural Paving vehicle grade pads. Looking at getting the basecouse done professionally & then installing the pads on top - does anyone have experience doing this, and have any comments about durability / wiseness of decision? The appeal is the price (far cheaper than concrete), and ease of repair down the track (in case concrete or ashpalt cracked etc)
