Hello. I have built a small wall with 90mm Leca blocks by my chimney, but when we mounted a steel beam on it, we accidentally hit the wall, and it moved a few mm. The mortar has cracked the entire way from floor to ceiling. I need to saw out the mortar and reapply it, but since it's in place, I can't reach it with typical mortar using masonry tools... I simply can't apply it. There will be a gap that can be seen as 1 cm or a little more. It's about a 10 cm thick wall. Is there any mortar in a cartridge that I can use to inject the mortar so it really holds? I found something, but it's only for joints? Do you have any suggestions?
