Concrete repairs

Would any kind and preferably knowledgeable soul be able to advise me on a wee concrete repair problem I have, please?

A hairline crack approx 3 feet long has appeared in a section of my print pave concrete patio. The concrete was originally laid to a minimum depth of 100mm, and the crack spans the entire width of the section concerned.

After chiselling out a V-groove along its entire length, I did attempt a DIY repair using some readymix brick mortar about 2 months ago, but the crack has reappeared presumably because of movement caused by expansion and contraction.

I have done some Googling around but with limited success, and am confused by the products on offer as most seem geared towards the building/construction trades rather than DIY. The nearest I can find to what I think are my requirements is this site:

but the product (CrackWeld) is only available in the USA, from what I can see.

Does anyone know of a similar product or technique available here in good ole Blighty?

TBH, if you have a crack it's for a reason. And until you can get rid of that reason no amount of filling is going to have a lasting effect. It does appear that you have encountered the problem of differential settlement of part of the patio. I doubt if this will be easy to cure but it may naturally cure itself when any settling comes to an end..
