Fixing a groove/hole in concrete

[Karolisko]

Hi all,

This might be trivial for most of you but I don't have experience working with concrete.
We had some of our front of the house cracks and holes fixed with fresh concrete. Also under the gate.

The issue at hand is that the gate's bolt created a groove in the concrete and the gate moves with the wind. Does anyone have a good idea how to fix it without the need for more concrete? And if it definitely needs concrete, would it be just adding a small blob on top of what's there (after cleaning out any debris)?

Thank you in advance.

Got a photo?

It'll be a small groove. About the only thing that will have a chance of lasting long term is a proper epoxy repair mortar. Sort the bolt out so it doesn't get worse

That’s what the bolt is for , to stop it moving in the wind.

Apologies. I was sure I have attached those! I think they didn't finish uploading. I thin the groove got even worse /longer since taking the photo.

Agreed. But the whole plan works only if there is a bolt - sized hole, not a long groove.

Why not just move the bolt very slightly higher and then drill a slight indentation/hole in the concrete where you would like the bolt to hold the door open?

So why no hole for bolt ?

Borrow or hire an SDS drill and a sizeable bit, drill a hole for the gate bolt to locate into, then resin fix a length of metal pipe in the hole such that the bolt can drop into it. The drill bit needs to be a little larger than the pipe outer diameter and the pipe inner diameter needs to be a little larger than the bolt diameter

Repair the slot worn in the concrete with a bit of mortar mix. It won't be taking such a hammering from the wind when the metal pipe is in place

I have made a hole but it turned into a groove. Those guys who did the new surface must have mix it badly as it's so soft/crumbly. Too much sand it seems. But after your message I checked if I can drill deeper (below the new surface). I was surprised that my cordless drill was powerful enough to do it. Thanks!

Thank you. I might do it long term

How long ago was it laid?

Did you know about the benefits of keeping new concrete wet?

4-6 weeks ago.

I think I read it since (when trying to sort out the gate issue) but I wasn't told by them, which would have been helpful. How long do you keep it wet for?

They have repaired the job with screed sand. Not really suitable there.

It needs redoing with 5:1 concrete. You could even concrete in a wee bit of copper pipe to receive the bolt.
