Hello! I'd like to install two Oxford Anchor14s (Ground & Wall) to the front of my Victorian terrace as I have no side access. They are attached with expansion bolts. See pics for the bricks and paving slab I'm planning to attach them to.
Wondering if anyone has done the same for their bikes and if so did it damage your brickwork? Would this be a good idea, do I risk blowing a brick out, or damaging the structure of the 160+ year-old wall?
The section of different bricks in the middle is where an air vent once was (no idea of when this was done) and where I was planning to attach it to. I'm less concerned about the paving slab which is concreted in, though I guess there's a risk of smashing that.
Thank you so much
