Hi all, the corner of my garden is a brick boundary wall. I'm currently cleaning it up and will then paint and attach a floating bench with resin anchors into the brick. I have two questions:

1 The wall looks pretty rough and unfinished but has stood for since the 1920's perhaps and is otherwise solid. In cleanig it up I found some parts that were barely filled in with very loose mortar! This was little more than sand. I mean I just brushed it out with a stiff brush.

Before painting I want tp fix the pointing and fill all the voids. For the majority of the pointing I have a pre-mixed pointing mix I can use. I can also make up suitable mortar with cement and building sand if needed instead. For the finer gaps I intend to use Soudal Repair Express. For the larger voids in the upper right corner I'm considering a coarser mix of 1 part cement 4 parts sharp sand or something. Does this sound sensible, or am I barking up the wrong tree? Please school me up!

2 I need to identify suitable places to drill my M10 studs for the floating bench. In the picture you can see that there are some darker brick courses with the small edge facing out. One of these falls around the height I need to secure my bench. Would this be a good choice to drill an 85mm hole for chemical anchor, or would the normal course be better. Here's a shot of one of the bricks in profile so it looks like I would get a solid substrate for 12mm drill bit in the lower 50mm of the brick.

Thanks fpr any advice. I'm pretty inexperienced but willing to learn.
 
The wall on the right, appears to be rotating away from the wall on the left, at the top.
Probably lens distortion. I'm not saying they're absolutely plumb, but there's no real significant divergence. I will check it tomorrow though with my spirit level!
 
This, tells the tale...

If you imagine that RH wall, pushed to the left, it would all fit back together perfectly. Someone has obviously tried to fill in the gaps in the past, and the wall has moved even more, since then.
 
OK, yes, you're onto something!

I will say that whatever may have happened, it was long before 1980, because that's when I moved in, and nothing has moved in those 45 years. So I'm fairly confident in it surviving. Good spot though
 
You're obviously right about the desplacement. But I don't think there could have been any more movement. The vertical column of cement running down the corner is the gap that was filled after the displacement. And the doesn't look like it's enlarged much more. I thiunk the voids above it are where the filler has blown and over time fallen out. ( this wall was fully exposed to elements until a couple of years ago when I had another four courses laid on top and then covered with a flat roof.

I'll probably fill those voids, but wondered what mix would be appropriate, or if it really matters.
