I had a block paved driveway installed by a semi-cowboy outfit, the soldier edging course holding it in place was pounded down onto a concrete bed, after one winter it had broken free and turning the steering wheel was making the driveway "walk" sideways.
The actual concrete bed was still intact, so I glued the soldier course back in place with two beads of CT1 per block, and not one block has moved or come loose in the ten years since then.
I've just bought a fresh 5kg bag of sand and cement mortar mix for another job. I have no idea what the sand/cement ratio is because the manufacturer's (Tarmac brand from B&Q) data doesn't tell me. Is that likely to be suitable for this job too?

I think I have a couple of 'sticks' in my glues, etc container, it might have gone off ...
You've just given me an idea. Forget the cement: all I need are some pulped-up copies of Metro and a giant freezer plant and I could make my own shower-room version of Project Habakkuk instead!

If a bricklaying mortar mix it will be relatively weak. At least 4 parts sand to 1 part cement but possibly 5 to 6 parts sand.
Thanks,

No. It will be a much weaker mix
It's been a couple of weeks now, so here's an update.
I dismantled and cleaned up the whole quadrant enclosure, used sand and cement to fill the void behind the shower tray and stripped out and re-grouted all the er.. grout.
I re-installed the enclosure by following the manufacturer's instructions rather than the somewhat esoteric method which had been used by the original installer and then sealed it all with the CT1 clone OB1.
The OB1 is brilliant stuff! As well as sealing the enclosure/wall boundary, I used it to glue a plastic quadrant section along the wall/tray boundary. The shower has had plenty of use and I can definitely say the job's a good'un.
Did I mention that OB1 is the absolute dog's wotsits?
Thanks to all who helped,
Nick
