Concrete-mounted mailbox holder wobbles

[jahallåja]

Managed to fail at casting a mount into a concrete block to have something to attach the mailbox to. I have a parcel mailbox and got one of these to mount it on:



I used "gjuta enkelt" from Finja, which is supposed to be just poured into a hole with the appropriate amount of water and mixed around.



I think I wobbled the mount a bit too much to make it level in the concrete, so it set with a bit of play. Anyway, the mount wobbles, and therefore the mailbox, and I'd rather not dig up the block, knock out the mount, and start over.

Is there something suitable to fill with that cures so the wobble disappears..? Preferably easy-flowing so that it fills well down into the cavity.

I bought one of these but haven't tried it yet because I'm not sure how difficult it will be to press in the compound


What do you think?

Can you wiggle the fixture loose and lift it up? I think it would be best if you "start over" and drill two holes, clean, and then use some anchoring compound. It should be for outdoor use. Just trying to squeeze it into the existing gap might be worse...

There are indeed cheerful bends on the irons that go down, so it will probably be difficult to wiggle up unfortunately... Orka-borka....

How can it get worse? Not much better, I understand? Do you mean that it cracks completely, or something like that?

The geggamojan worked well, filling the gaps around the poles and stabilizing them.


Unfortunately, the platform itself still wobbled on the mount, as it did not have direct contact with the ground (which I probably should have figured out it needed). But with some gravel and a stone slab under the metal plate, this wobble was also reduced to an acceptable level.
