Hello!
I'm going to build a fence next to 40-year-old L-brackets, and the question is how to best secure the fence in the ground on the inside of the L-brackets. Pictures attached below.
After reading through many threads on the forum and searching online, I'm mostly considering two options. Attaching the fence to the L-bracket (as many have done on the forum) is not an option as the other side faces the community's common flower bed, and the L-brackets are 40 years old, which I assume increases the risk of unsightly cracks towards the bed.
However, I could consider using a rotary hammer to drill holes 45* downward in the side of the L-brackets from my side, and secure short rebar with chemical anchors, then cast fastening brackets in some sort of small concrete post that mainly attaches to the L-bracket.
The second solution (to reduce the risk of damage with a rotary hammer on the L-brackets) is to cast a proper post on the inside of the bracket as you would on flat ground, and perhaps pour some concrete between the bracket and the post afterward.
The fence will be just over a meter high and 23 meters long, with corners and continued fencing on both ends for added stability. Part of the L-brackets has a level difference of 15 cm, for which I plan to place the fastening bracket at the height of the lower L-bracket.
Do you think option one would work without rebar, provided I clean the L-brackets thoroughly so the new concrete adheres to the brackets? It's "just" a fence that needs securing.
Is there any obvious solution I've missed?
PS the small holes I've dug in the pictures will be moved to the lower L-brackets so I can screw the fastening bracket from both sides.
As I wrote, unfortunately it's not an option to attach anything on or through the L-supports since I mainly don't want to change the appearance towards the shared flower bed, even if the L-supports stand on my side of the property line. So unfortunately, I have to solve it another way.
