Repairing paving - grouting / gap filling

[Mr Moofo]

I am blessed with house with some very 1970 crazy paving - after we had some building work done a few years ago, the weight of machinery going over it had crack it / unseated some of it ...
And some is now loose enough to trip over - and at some stage that means I will do.
It would appear to have been laid on a bed of cement / sand - but the gaps between stones are quite big - and i some cases earth filed.

What is the best way to repair? I have read on t' internet that a 3:1 sand cement mix as a bas and brushed in dry would work. But as some of the gaps are quite big.

There are also quick setting fillers like Silk Quick Setting stuff. Am I bet using this ( I am not talking about a huge area - but a lot of gaps.

One thing to factor is is I have a dog , who has no manners at all. Keeping him out of wet cement may verge on impossibility ( those i would over with OSB board etc.)
Or is it a case of filling the small gaps with sand / crew mix dry, and using the Silka stuff for the big holes?
Ta!

You’ll need to lift and relay any loose paving stones which will likely loosen those surrounding the current loose ones so you’ll possibly end up relaying the lot. IMO no jointing compound will stop a wobbly slab for very long.

IME paving is either:

Laid dry on compacted sharp sand
Laid dry on 3 (or 4):1 sharp sand / cement base
Laid wet on spots of 3:1 / 4:1 sharp sand cement mortar
Laid wet on a full bed of mortar

Which one is best depends very much on the sub base, use, materials etc. In terms of jointing, I’d go with brushing in dry mortar mix then dampen with a gentle hosing of water and point up with a trowel where needed before covering to stop the dog.

I’m relaying block paving which will be bedded on compacted sand with kiln dried sand brushed into the cracks. The path I’m ripping up has been laid like that with a sand cement dry mix around the edge bordering onto the lawn which I’ll repeat. I laid out most of my sharp sand on Saturday before rain stopped play which the dog used as a sand pit play park before I managed to get a tarp over it all.

5) Laid directly on the earth as mine is !
Its a pretty shonky crazy paving - so I just want to stabilise . TBH most of the stones are perfectly stable - just crack - and lifting if caught by a shoe etc ...
