Take out concrete post in garden

[Gunner786]

Hi guys. Im thinking if putting a fence up but need to get rid of this concrete post first. Any idea how far deep they go and wether they have any concrete block underneath?

Or any suggestions?

Probably about 12" and a bucket sized lump of concrete under each post.

Easiest way is probably to separate the vertical and angled post, then wiggle each post like a wonky tooth and pull the entire thing out like a tooth. What may help is excavate around it with a trowel, allowing movement, but over a couple of days chuck a couple of buckets of water into it.

I had one where I had to use a kango, because a nearby post's concrete had blended in with the older one

Just dug around it abit. Its lickily not too far down. Problem is theres a conservatery right next to it my next door neighbours so i need to be very careful breaking it to pieces.

I once used an engine hoist to lift a post straight out prior to enlarging the hole and then replacing with more concrete.

Update: i have removed the horizontal one totally along with the concrete holding it. Was an easy enough job. Now the vertical one i have gone down 1 foot and ut doesnt seem to want to end lol.

If you don't need to put a post in the same position you could angle grind it as low as you can.

If you are intending putting a new post in its place, then I would be trying to dig down the side of the concrete plug it is set in. at some point you will be able to wiggle the post and its plug out all in a oner.

After finally getting the old posts out i move onto the next stage....

1ft gravelboard 5ft panels.
If i flush the concrete post against this wall then it wont go under ground because theres 2 bricks and 1 ft of concrete pointing out at the bottom.

If i put the post into the ground then there will be a 1ft or so gap between the post and the wall. I dont think the wall is that strong as you can see the state of it, its about 65 years old. Will i be able to cover the gap with something that will look nice or will it look nasty?
The priority is the rigidness and strength of the post but i also dont want to be left with a 1 foot gap that sticks out like an eyesore unless theres something to fill it with...

Can you lay your hands on an SDS drill?

What is this concrete and brickwork doing? Does it belong to you? Will your fence run beside, or end-on to it?

You can "copy and paste" photos into your post.

Will start from it.

Take down the brickwork. Secure a 4 x 2 to the house wall and then run your first fence panel off this to the first new fence post. With any luck the fence posts will be in new positions. Gravel board can then sit flush to the ground and protect fence panel.

It would be nice to be able to include a hedgehog hole in the fence? Perhaps the 12" gap could be used for that?
You could insert a 12" board from the top that stopped 12" or so short of the ground.

Update: i ended up making the bottom 2 bricks level with the rest of the wall amd will put the post flush now plus 2ft depth in the ground with postcrete. I needed to know what size bolts will i need and rawplugs to fix the concrete post to the wall?

 

[Tigercubrider]

does the post have holes in it?
given the postcrete you probably don't need to fix it

Will drill the holes myself
