Postcrete and a fence post support.

Just ordered duraposts. Will see how I get on

Anyone used postcrete with one of these Vs traditional concrete, is rather it set fast.

It's a tight fit hole so wondering if there is time to mix it up get it all straight before it sets.

I wouldn't personally use postcrete in your scenario. It's fine for resisting lateral movement when put around a post but the item you have linked relies on it being embedded within the material. The postcrete will likely break up over time. Given you are only filling a small hole I can't really think of any benefit of using postcrete over a bag of fast-setting concrete.

Hey guys, sorry to piggyback on this thread but I'm in a very similar situation. A metal gate post has snapped and left the bottom bit still in the ground and concreted in. It's basically left a hollow section of 80x80 and about 200mm deep.

I was thinking of putting a metal support into the hole, cementing it in and using a timber post as a replacement (can tie into the fence).

which of these products do you think is a stronger solution?

1) a metal u support bracket with 200mm rebar
2) a fencemate concrete in swift clamp

Thanks for reading!

The worry for me with something like the fencemate is getting sufficient concrete tightly around it. Think I'd rather fill the hole with concrete then push in a u support with rebar.

Yes I think that's what I'll do.

You could plane an oak post down at the bottom to be a drive in fit inside the steel tube. But ideally get the old box section out and replace with a fabricated then galvanised gatepost if you want steel.

Don't waste time and money on softwood gateposts, most softwood these days is junk (feel how lightweight it is compared to decent old timber). Softwood posts, gate or fence, just rot away, even so called treated ones now the EU have banned proper creosote and arsenic based rot proofing treatments.

Best CHEAP gateposts are used sleepers, the old ones with tar oozing out of them, not new ones a kid can lift up, (the sort garden centres usually sell as "sleepers", but aren't).

Thanks for your comment and all that info. I agree that getting the old section out and replacing with a galvanised post would be the best long term option. However I'm going to try the u support and timber method because it's a favour for a friend and it only needs to be a shorter term option. It's the receiver side of the metal gate so I won't have the extra weight of a gate swinging. Hopefully it will work but we shall see!

Yes I agree. It would be a very snug fit with the fencemate but I was thinking that may aid the strength of the support. Nevertheless I'm going for the rebar and u support option and hopefully it will work!

No problem, and good luck, let us know how it goes.
