Type of anchors for surface mount alum. fence, into pavers

Good day gang,

I am installing part of the aluminum ornamental fence on top of pavers. The pavers are quite large, around 2 3/8" in thickness, 13" x 19 1/2".

I was planning on using some anchors that can be removed if need be like Cobra SuperSleeve, but then I also saw that Tapcon have the LDT option.

I just wanted some advice as I don't want to crack the paver, as the fence is being installed near the edge.

Is one bolt better to use over the other?
Should I drill all the way through the paver and use a longer bolt?

I am planning on supporting the surface mount of the fence pole with a larger aluminum plate to distribute the weight (sideways force if the fence post is hit), just unsure as to what hardware to use on the bolts.

I like that the Tapcon can be taken out/removed.

Thanks in advance!

Welcome to the forums!

I don't see a paver being stout enough or wide enough to support a fence. It's always best to go deep to secure a fence, wide is a distant 2nd.

Pavers are no more structural than the carpet in your living room. A concrete slab yes, pavers no, nothing really holding them down but their own weight and that isn't much.

Your fence becomes top heavy as soon as you put it up. Pavers would act like a wine glass, they sit nice on the base, but you can certainly tip one over if you applied force to the top. That is why fence posts are anchored into the ground to give it lateral support against forces that push on it.

Thanks for the feedback. I am aware that being anchored into the ground is best, but at this point that isn't possible for me to do, so I need to work with what's available. The pavers are 123lbs each. The fence is aluminum 4 feet high, so pretty light, and in some parts, the fence will be enforced (for lateral force) against 6x6 posts that I have installed for the pergola. Not ideal, but again, I have to work with what I got

I will be using these anchors for the base plates of the fence posts: https://www.cobraanchors.com/fr/cobra-tork-11747.html and will do some testing on paver samples (smaller than my pavers size wise, but same product and thickness) that I got in different colors.

your fence is going to act like the sail on a sailboat. wind will be the biggest problem.

if it was me:
i would remove the paver where the fence post will go, dig a hole, put in a sono-tube and fill it with concrete. then attach the mounting bracket (for a 4x4) to the cured concrete. Then cut the paver around the post.


If you cant do that, remove the paver ...... dig a hole, dump concrete and fill with water, mix. Then drill through paver and anchor the paver to the concrete below. that will atleast give you a little bit of lateral support. then attach fence post bracket through paver.

Anchor the post to ground and cut the paver to fit around the post.

Hi everyone, just wanted to close this out. Thanks for the feedback/responses, and sorry for how late I'm replying here.

I did install the fence (aluminum) and use spikes that I drove into the ground (just on the outside edge where the pavers ended) on which the fence posts were installed. It turned out nice, the fence is light, and the inspector passed everything.
