I've recently found out the the previous owner of my house has laid the block-paving driveway incorrectly. The driveway has covered the air bricks to the house and I now have a damp problem. I've been told the only solution is to remove all the bricks from the drive, then to dig about a foot down and then relay the block drive. Its quite a big drive and the problem runs from the front, round the side and at the back of the house. Is there any other way of fixing this problem???
