I have a garden water feature which is/was contained by an old man-made stone 'brick' wall. The jointing material used was an old type of very coarse grey mortar.
I have started removing the loose 'bricks', some of which are still joined together in small sections. Everywhere the jointing medium is intact and the 'bricks' just come loosely off.
I would like to replace the sections and the loose 'bricks', retaining the jointing medium intact. When complete the wall is about 0.5 metre high, curved and 2 metres long.
I look for an adhesive or material which would be very thin and unnoticeable, to join the sections and individual 'bricks' back together, appearing never to have been apart. It would need to be waterproof of course. No force is/would be applied to the wall when complete.
Possible?
@makem,
A picture might help. Look into 'landscape foam adhesive sealants'. This stuff expands so not much would be needed in each joint, and the excess will squeeze out. When it dries cut and scrape it off with a putty knife. It's messy, though, and you might have to look for one in grey, although a thin black line might not be that noticeable. The traditional alternative would be to use a lime-based mortar but it would need to be a very thin layer and it would be difficult to get it to stick in a thick enough layer to work effectively.

I was thinking, maybe a grey waterproof tile cement work work but need to check if affected by frost.
Img does not seem to work for me

@makem,
That looks like a good choice and it's suitable for exterior use.
Yes, it is possible to repair and rejoin the sections and individual bricks of your old man-made stone wall while retaining the existing jointing medium. To achieve a seamless and unnoticeable repair, you can consider using a waterproof and thin adhesive specifically designed for masonry or stone applications.
Look for a stone adhesive that is formulated for bonding and repairing stone, brick, or masonry. These adhesives are often designed to be thin and have good bonding strength. They can provide a strong and waterproof bond while being less noticeable once dry.
