There definitely are agents as I use them at work but on an industrial scale so can't really bring it home.
We pour cement and it's solid within 30 minutes. After 2 hours the compressive strength is 24 N/mm2 which means nothing to me but the span will take 300+ tonnes in weight.
Sadly I'm working every day including weekends till mid October with only days off to switch between night and day shifts.
My mate will lend me his Grinder and cutting discs, just got to arrange it.
My thinking is now heading back to the idea of cutting horizontal slots along the footing and slotting rebar in and then making good. If it works out would be the quickest, easiest and cleanest of all the repair options. Very similar to the Helifix method but much stronger.

Wanted to make a start today, but had work on the phone all morning even though I'm on nights tonight and now it's too late to start anything serious.
So to tide me over I injected this stuff into the cracks:

I didn't think it would do much but within 15 minutes it has set absolutely solid. I used a spatula to help push it deep into the crack and the spatula got stuck solid and I had to leave it in there and cut the end off.
By the time I finished messing around trying to get the spatula out, the last bit in the tube the had gone rock solid.
If the collar cracks again with this stuff in there then the forces against it must be incredible.

Sorry to hear rs only just reading through.
I extended the wall on my pond, when joining the new shuttered and poured concrete wall I did the following.
I roughed up the old concrete wall and then drilled holes into it, I then used resin and bonded rebar into it.
I also wire mesh into the middle of the wall as well.
I wet the old wall just before the pour and has work fine.
May work for you on your pond, you could also dig out under the old concrete to help strengthen the repair.

Thanks Sim.
This is exactly the repair that's been running through my mind.
Need to take the water level quite low as will need digging for the extra footing extension.
Thinking of extending the footing out by 6" and then paint it and use it as a shelf for plant pots etc.

RS you are missing a trick here as you could use this repair to extend your pond
I've already put the shovel and pick in the car so you just need to decide if you want to extend by 4ft, 6ft or 10ft and I'll be round later to make a start OK

Only have decaf... And it's probably 2 years out of date as only person who drinks it is my mum when she visits once a fortnight!
Don't you worry.... The extension idea has been playing on my mind, but I can't go through that all over again. If I did extend, it would be downwards to increase volume.

24 hours since resin injection and its held solid.
Not sure if I can risk leaving it at that for a while or not.
Doesn't help not knowing exactly when the movement occurred, but have now found a photo from mid-July and a crack is visible in that picture as well. There is definitely no crack in photos from April.
Might end up not going on holiday anyway, as its booked with Thomas Cook. But for some reason it doesn't excite me that I might be able to stay at home and repair the cracked pond instead!!!

We’ll all keep our fingers crossed for the pond and Thomas Cook!
