Repairing crack in Wall

    If I fill this with mortar, can I keep the mix a bit on the wet side so that some might soak its way down to the bottom or is that a bad idea.

    Is there any chemical alternative that you could pump in with a mastic gun.

    Look up "non shrink grout" on google, I've seen guys use this with empty silicon tubes in a silicone gun and even with icing bags :eek:

    Is it an ornamental wall?

    Reckon you would need to sort out the cause before you re-do the joints. You will just end up having to repeat in a few months. I would guess your footings were a bit on the light side which is causing the movement as the crack starts at the top and follows the joints.

    If you used a very fine sand in your mix you could gun it in, but because of the colour difference it would be really obvious.

    The outside of the wall is lined with red bricks and has no sign of cracks or weakness.

    The foundation is sound, so not worried about that as there are no cracks at all in the first 3 rows above ground.

    How would I get the mix into a cartridge, do I just prise out the end of an old cartridge.

    I've used one of these before...

    messy job but keeping the mix wet and fine would help to do the job you are looking for. I picked up one in Lidl's a few years ago for just a few euro.

    Good luck with it.

    This bulk gun can be used with pointing mortars, not normal sand/cement mixes. Look up "Easipoint" mortars. They should be able to help you.
