Attaching post shoes to existing casting.

[Odmann]

Hello!

As the title says, I need to attach a bunch of post holders to an existing concrete foundation for a fence building. I'm considering either drilling holes in the existing concrete and filling with anchor compound, or making a slightly larger hole and fixing with something like expanding concrete?

Is one of the options more advantageous compared to the other?

Best regards

How high will the fence be. If it is high, long mounts are required, and post shoes are not sufficient; instead, it should be postjarn that are set deep in the wall.

Combination hammer and a drill 2 mm wider than the post shoe, then anchoring compound + post shoe. It's good to use compressed air or a hose to blow out the hole beforehand.

I installed these on our fence, the first pair only with wedges but the irons wobbled, so the rest with wedges + anchor mass. They are rock solid.

Thankful for the answer!

The height of the fence will be about 80cm.

Stolpjärn is completely new to me, I didn't know it existed at all. It sounds like a good solution with the wedges at the bottom.

Grateful for the reply!

If it's a long straight fence and it's in a windy area, it will easily break at the fastening. Post shoes only have support in a fork at the bottom and don't hold well for sway. So post holders are best and hold well, a bit more work, but why maybe redo it later. If there's space in the wall to place the holders so that they absorb the twisting of the fence crosswise, that's best. It's fine to fasten with a carriage bolt through the post, over time the post will shrink a bit, allowing for a little extra tightening.
