Repairing sinking block paving

[blue_eyes777]

Good morning .

Some of my driveway block paving is sinking.

Any advice on how I can lift them and relevel please?

Do I need concrete too?

 

[Wayners]

Just lift blocks. Fill and replace them.
I have similar problems with slabs that sink. Ground is wet I guess

is there a drain or pipe under it?

Kill that ants nest under the blocks, thats what is dragging the sand out, then re level with sand and tap home.

Thank you all.

What tool can I buy to lift the slabs?

Been like that for a couple of years. Started when we bought a heavier car.

It's a fiddly one. There isn't a tool, but we use a pair of pointing trowels to get the first block out, then a pick or a brick hammer to ease the others out.

You'll need to remove as much of the fill material out of a single paviour joint. Once you can push a trowel in there, you should be able to wriggle the first block out.

Start on a convex paviour and not a sunken (concave) one.

Once you get the first one out its easier getting the rest out, you need a straight length of timber 6 foot will do looking at your pictures and a lump hammer or a rubber mallet.

Put this on your Xmas list, will also come in handy as a spare mixer handle
