Fixing existing fence posts to brick wall

fixer2 · 13 Apr 2019

My garden wall is single brick around 3' tall. I then have a fence with panels that sits above/resting on top of this wall. My fence posts are 3"x3" and on the garden side. The fence panels are 3'x6'.

My question is how to fix the fence posts to the wall to make it more secure, as it moves about a bit in the wind. I think there is an option to use some kind of bolt through the post into the wall, but I am not sure what to use or really how to do it. Any advice would be appreciated.

So are you planning on the entire fence sitting on the wall?
Or the posts into the ground next to the wall, and the panels secured to them?

Leverage is going to be an issue if you just screw or bolt to the top of the wall

the posts and panels are already there. I need to secure a couple of the posts by putting a bolt horizontally through the post into the side of the wall.

thanks Ray. Do you have any tips on using these bolts? Do I drill a hole just a bit narrower than the bolt right through the wood and into the brick, then just keep tightening the bolt? Just wondering how the bolt will bite into the brick.

Personally I would drill a hole through the post and brickwork that is the same diameter as the shaft of the bolt leaving the threads to cut their own way for a tight fit.

If you have access to both sides, put threaded studding right through the wall, with a nut and penny washer on each side. If you are on the coast use stainless, otherwise galvanised will do. Painting it before assembly will improve its duration of life. Fences tend to sway in the wind and this loosens fixings and rubs off plating.

Studding works out much cheaper than bolts, you can get it on ebay. I use M8 which was intended for suspended ceilings. The galvanised is easy to cut, but stainless is dearer and you can order it cut to size on ebay.
