Concrete Path Repair

irishgal21

Hi all,
I've tried using grab adhesives on a path with 3 broken pieces, with tek7 and Gorilla glue but eventually they become lose. What's the best way to tackle this ?, (see pic). I am willing to mixup some ready mixed concrete now if its the best way but I've read that I will still need "concrete adhesive" around the edges of the old concrete so that the new concrete bonds to the old concrete ? else the new mix will also become lose in one large lump.

Is this correct ?

If so can someone recommend adhesive and concrete available in Dublin ?

Hi,
Since I'm the 41st person to view the picture I felt obliged to post the first response; rather than leave you hanging,

That is indeed concrete,
I'd go to my local woodies and purchase a 5kg bag of ready to mix concrete,
Also a strip of 1" pine wood and some nails,

Remove all of the broken concrete out of the footpath
Then nail down your wood to create a sort of reservoir for pouring in your cement,

Use some of the pine wood then to skim across the top; leveling out the concrete with the existing height of the rest of the footpath,
Leave it for two days to fully set dry then remove the strip of wood.
Job done

Might not be required but probably no harm to put PVA on the exposed concrete that you are trying to bond the new concrete too. Itll help the new concrete stick to the old.

Thanks for the replies, yes I was more concerned about making sure new concrete bonds to old.

I'll go with ready mix concrete and pva.

Thx.

mix the PVA with water and make sure the surface is wet.

Mix a bit of the PVA in the concrete also, better still if you can get a bit of SBR. I would just grab a bag of Kilsaran Post10 which has a strength of 35 Neuton and add the adhesive as above.

Use somethinhg specific to the purpose and that's going to hold over time.

A concrete epoxy repair is probably your best bet.

Have you used this?
I personally havent seen any of these that lived up to their expectations, they are a quick fix and not for long term.

No, I haven’t used this product but have a very similar issue. Have previously tried the cement fix which failed and after doing some research, looking at a couple of YouTube videos and reviews of similar products, I had decided to give it a go. Haven’t gotten around to trying it myself yet though.

No i wouldnt dream of using it, you cant beat mixing your own along with the SBR
I can guarantee itll go nowhere, especially if you paint the sides and base with the SBR.

I have used gripfill etc and a few adhesives most are gimmicks.

Drill into the existing concrete and insert small pins into it and place new concrete over these pins which will act as a tie to the new and old.
