Hello,

The small fence project including the gate has encountered an obstacle. Two out of three post brackets (see image) were successfully cemented, but the third one can be wobbled. Naturally, it's the post that's supposed to carry the gate, so it needs to be fixed. It's the bracket itself that is loose in the concrete base. The feeling is that the concrete hasn't gripped around the rod that's inserted.

How do I fix it best?
There's currently a 30 kg base. Should I try to pull out the ground anchor and drill a small hole and re-cast it? With concrete or chemical anchor?
Or do I need to somehow blast the entire base and start over completely?

Now, I may have misunderstood, but when it comes to gates, you probably prefer to cast down the post you're hanging the gate on, maybe 50cm?
If it's "just" anchored in the ground, there will be a significant strain on the fitting when the gate is slammed year after year.

To answer the question, previous advice has been given to use anchor mass. But that was for wooden decking...

Addition: I just saw that the plinth is only 30kg, I think that may only be sufficient in the long run for a very light gate...
 
I would have left the plint and proceeded with ankarmassa.

Thanks! Yes, you’re probably on the right track because in hindsight, it seems much more sensible to get the post itself down a bit as well. However, despite the way I did it, there's not much margin to fit the fence itself at the height of the post, so it couldn’t have been driven too far into the ground.

I think I managed to save the situation. I drilled two holes at the bottom of the ground fixture and further down into the concrete. Used anchor compound and two threaded rods as braces. Also applied anchor compound around the foot of the post fixture.

We’ll see how long it holds up…
