Hi, our driveway comes off a steep dip from the road, gradually downhill to our house, 200ft away (i think), driveway is in a 'L' shape. We want to lay gravel around the house but we will need grip to go up the hill and out onto the road so we were thinking either putting down cobbleblock or tarmac all down the drive, just the gravel around the house. Would the gravel not just drag up onto the tramac etc which would you think was best, low maintenance in mind. Or if you have an alternative that may work out cheaper, suggestions would be most welcome. Thanks.
