I should have mentioned that r'girl, about the wet and wintery weather affecting it etc. I expect it depends how bad the hole is is, how fair the weather is in the coming weeks, and whether it's worth leaving till a more suitable time.

Interesting comments - thanks. I'm hoping to have the drive done next year (although OH hasn't yet agreed!!!) so the pothole fix really just has to last the winter. I wouldn't normally bother but of course it's developed just where we drive in and out so getting to be a nuisance which I don't want to get worse. I'll try the Postcrete first as I've used that before.
HOW NOT TO FILL IN A POTHOLE! I couldn't get hold of the Blue Circle concrete repair stuff so was recommended a can of UCan concrete repair by the B& Q manager. This morning being about 12C sunny and dry I read the instructions and started filling it in. I'd just finished smoothing the top when I accidently kicked over the small jug of water I'd put nearby in case I needed extra. Being on a slope, it ran all over the concrete mix. I threw some hort,sand all over it to try and soak up the water but fear it's ruined and I'll have to do it all over again. Talk about live and learn!
As long as the hole was dry before you filled it, water over the surface afterwards probably won't be a problem. Concrete will set when totally submerged on the sea bed. In fact water isn't a problem at all, as long as it stays as water and not ice (or steam, but that's unlikely, even with global warming). Ice is bigger than water and it WILL expand - it's immensely powerful, so if there is a 'pocket' of water trapped under the new blob of concrete, when the water freezes, the weakest point of the surroundings will give - and 99 times out of 100, that will be the concrete patch getting lifted out of the hole. Pouring water (or rain) over the surface won't trouble it, as long as it can't get underneath.

Aaah! the hole was still a bit damp right at the bottom before I filled it and I suspect the water from the natural spring a couple of feet up will seep underneath anyway - rain's expected all day tomorrow so that will be interesting! Hopefully our new neighbours might be shamed into relaying both entrances as it was his heavy building lorries that made it much worse!

If a particular compressive strength is required, Postcrete should not be used"
I'd stick to the repair concrete, it works the same but will take the weight of cars and should be more frost proof.
