Hi all,
I have a patio that has been down for ten years. It is still in good nick, and is generally fine, but two of the slabs have become slightly loose, and wobble fractionally now if I stand on one side of them.
What's the recommended cure? I've just done a bit of research and seen some suggested bodges involving drilling into the surrounding pointing and inje cting expanding foam under the slab to stabilise it. A friend has suggested lifting the slab, using a few blobs of epoxy stuff to "glue" it back in pl ace and then repointing around it. What do you think?
Cheers,
Martin
