I have an external cracked brick and want to replace it, but I'm not sure how to deal with the cavity wall insulation.
What concerns me is:
1) when I remove the brick, the wall insulation will spill out.
2) when trying to replace the brick, the mortar will be pushed into the cavity and sit behind the brick.
(which may connect the external wall to the internal wall with mortar, thus damp!)
I haven't any more insulation to refill any lost.
I have a grinder, with mortar removal disk, to get the brick out.
I've searched for videos, but I can't find any with how to deal with insulation.
Any help would be welcome,
