Paving bricks meet Tarmacadam

    Hi Guy's,

    I have an issue with my driveway (primarily car movement's) , where some of the paving setts have become loose - pulled away from tarmacadam basically at the part where they join. Does anyone reading this know of a way to 're-attach' these to tar - I wanted to avoid if possible using concrete as this can easily enough tarnish the cobble. This is creating further movement up along driveway.

    I hope I've explained the symptom and what I'm after. I will upload an image to clarify later on if possible.

    Tks.

    coxy123.

    Hi,in the image there seems to be none of the fine paving sand in between the joints,this is important to hold the paving together,adding this sand may help.Just pour over driveway on a dry day and brush in,keep some back and re-apply in a week or so later.

    The row of paving bricks that meet the tarmac should be have been haunched in concrete ideally.

    Exactly as sakura has suggested, the absence of silica sand in the joints has allowed amplified movement of the setts which is pushing one against the other till it reaches the tarmacadam. Get the sand in the joints and make sure its silica sand as its specially graded to ensure it gets into every crack. If this does'nt work it may be settlement of the drive and u need to look at a bit of a relay but try this first. Hope it helps

    Thanks for the replies - I happen to have a bag and a half left over of the sand you mention - I will give that a go and see how I fare out.

    Brushing in the silica sand now at this stage wont make the driveway look any better.


    If you want to fix it propperly then you need to take up all the pavers.

    Then make sure that the sharp sand base below is level and not sunken down or in.

    Relay the pavers correctly up against each other and then brush in the silica sand to prevent them moving and deforming the lines of the pavers.
