Pointing Solutions To Moving Patio

[Stayahead]

I would appreciate assistance with the following please. Some years ago I had a patio laid in my back garden. Three years later all the pointing cracked up. I don't think it was due to bad workmanship since my garden moves. I replaced all the pointing carefully, hoping that the movement had reached its limits (though I live in a clay area) but a year later it cracked up again. I removed it all a second time and there is now no pointing. I check and remove any weeds regularly. Wickes once sold a mix to ease this problem but it only worked with a slab up to a certain thickness and my slabs exceeded that. Has anyone encountered this problem and found a solution? Many thanks

A bit of a coincidence you asking this today, as I've just received my 2nd batch of "joint it" today (I didn't quite have enough with the first batch).
I don't know if this will be suitable for your's, but t's dead easy to apply - you simply brush it in and let it set.

There's a video demo on there with full explanation, etc.

You can buy it from Ebay. I got a 20 kg one for £36.99

Giz's link shows a good product, but it may not solve the problem.

Any finished surface is only as good as what is laid underneath it. From the fact that this problem is ongoing, it would suggest that the slabs are moving because whatever is under the slabs is simply not stable.

Sadly, it's a common problem Ground preparation is vital for any imposed load. Possibly, the only long term solution is to re-lay them.
