Bit of advice needed on a fence i am trying to construct.
At present my boundary wall is a 140mm (6") wide 1100mm high block wall finished with pebble dash and a concrete coping.
I basically want to have a timber fence above this for a bit of extra privacy/ security/ windbreak.
Ive basically 3 options as i see it;
1) Sink the 100x100mm posts into the ground on my side of the wall with a concrete found and also bolted back to the wall. The disadvantage to this is that i lose some width to my path. (Path is 1480mm wide at present). And also i would have to dig through the concrete path and possibly the found of the wall to get my depth.
2) Bolt the 100x100mm posts directly to my wall with no found on my side of the wall. Again i lose some width to my path. With this option do you think i would have structural problems with the wall with the windloading of the fence? (It can get very windy where i live).
3) Remove the concrete coping and make/ buy a steel "shoe" to hold the 100x100mm posts to anchor fix it to the top of the wall? Advantage is a cleaner looking fence. Again would there be structural problems with this option?
Thanks,
Anton
