Moonshine Posted January 25, 2020 Share Posted January 25, 2020 A fence post has broken off at the base leaving just the concrete foundation. Does anyone have any tips of how to remove the concrete in the ground so that I can put in a new post with associated concrete? Link to comment Share on other sites More sharing options...
joe90 Posted January 25, 2020 Share Posted January 25, 2020 Having a JCB is a great help for this!!!! I have had to resort to manual digging in the past which is hard work and depends a lot an how much concrete was used. If the hole was dug with a digger there may be loads of concrete around it. Hope someone can come up with a better solution fir you. Link to comment Share on other sites More sharing options...

PeterW Posted January 25, 2020 Share Posted January 25, 2020 You can buy repair posts for this sort of situation if the concrete is still intact. Link to comment Share on other sites More sharing options...
Declan52 Posted January 25, 2020 Share Posted January 25, 2020 Put a slimmer post in. If it was a 4*4 post put in a 3*3. Or get the kango/crow bar out and break it up. Or dig around the concrete and remove it as one lump if it's not a massive amount. Link to comment Share on other sites More sharing options...
joe90 Posted January 25, 2020 Share Posted January 25, 2020 Best bet is to drill the old wood out with a long drill bit and shave the new post to fit the existing concrete 1 Link to comment Share on other sites More sharing options...
Onoff Posted January 25, 2020 Share Posted January 25, 2020 Could you pour petrol or similar down and burn out the old bit? Link to comment Share on other sites More sharing options...

nod Posted January 25, 2020 Share Posted January 25, 2020 I removed half a dozen at our old house before we moved If the stump that is left is still relatively sound drill a 25 mil hole about 200 up Nock a long chisel through Then simply jack it up a bit at a time on either side It left the concrete in But I just moved the posts up Link to comment Share on other sites More sharing options...
Simplysimon Posted January 25, 2020 Share Posted January 25, 2020 when putting in new posts it was good to make up a shoe in lead to the depth of the concrete, silicone around the top edge to prevent water ingress and when required lift old post and replace, this would depend upon the number of posts. as suggested above wrapping and sealing in dpc/dpm would do a similar job.

Gone West Posted January 25, 2020 Share Posted January 25, 2020 We had a similar problem when we replaced one of the fences. The installers had kindly put the posts in 600mm deep and put around 150mm of concrete at the bottom of the hole. When the posts broke at a later date they didn't replace them, instead they concreted a chunk of angle iron to the post and strapped the two together. As a result we had to dig out two lumps of concrete for every post. The only way we could do it was with a spade which was a real pain for 25m of fencing.

Moonshine Posted January 25, 2020 Author Share Posted January 25, 2020 (edited) Cheers for the advise, I ended up drilling the post out, down as far as I could go, approx. 1 foot. What a pig of a job, 3 hours to put up a single chuffing fence post! I have put an extra layer of post Crete on top of existing concrete. There was damage Edited January 25, 2020 by Moonshine Link to comment Share on other sites More sharing options...
