    What can I do about a sunken block paved driveway?

    Driveway Contractors

    Hey there, I had a block paving installed in my driveway some six years ago but it appears to have sunk by now; do you know why this has happened and what can be done about it? Should I hire a professional?

    "It needs that area lifting to check the sub base to see what has sunk dig out to make sure you haven't got a broken pipe in that place then reinstate with new type one sharp sand then blocks"

    "Wherever it has sunk, it needs more hard-core put down, levelled off with sharp sand & replaced."

    "The sinking is most probably caused by not dug out enough and hardcore up to sufficient depth and whacked down correctly I advise to lift the sunken areas lay new sub-base whacker down so solid to a min 300mm then relay block paving making sure you have a breathable membrane down to prevent weed and grass coming through in the future"

    "This thing happened all always after 6 years because of solid moving and because of water, one thing you can do instead of 150 cm of hardcore you supposed to do 200cm of hardcore then is last longer"

    "Obviously, there isn't enough hard-core underneath. Need to lift the sunken area and check the sub-base add more if required and compact then relay blocks"
