Pulling out concrete post base

[dig-dug-dan]

I dig the soil away each side of the ball of concrete, hammer the claw attachment into each side and lift with the puller. It gets 95% of them out, just the odd one it wont lift, due to being too wide, or the concrete tapers the wrong way

As above, it makes the job so very much easier just to stagger new posts in between old concrete.

 

I guess your only issue would be if the old concrete is raised and preventing you fitting new panels level or if putting in gravel boards you would just need to cross cut top of concrete with a diamond blade disc cutter and chip away amount of concrete required to fit new panels and or gravel boards level.

It's the way to do it although occasionally you find someone else already had that idea haha

some erectors put concrete in the bottom of the hole then chuck soil etc in the middle then concrete on top. How do you pull that out?

I find in that case break the to concrete away most of the time the post under the ground is still solid. Wrap a chain around it and pull it out. At the end of the day every post is different. I take a breaker, bars and post puller with me to cover all bases.

I use a hi lift jack sometimes known as a farm jack, and a strop , a little bit of imagination and a lot of luck

If there is nothing left in the whole I have little 10 tonne rams I think they are made by enerpac about 2.5 inches high extending to about 4". I use a hydraulic hand pump. when the ram grips the hole put a lifting strop round it. you can either use a scaffold pipe for leverage or forklift/ digger . If the footings are weak they sometimes break in half but that just helps if you dig out.

The last time i took on a little fencing post job that called for the fence post and concrete to be removed,the original contractor had poured what looked like the same amount of concrete as would be specified into making a large german underground bunker.

After that episode i now subcontract all fencing jobs out.

Love it.

 

Never tried a post puller/farm jack but often wondered about them.

 

For us, if the post base has to come out, we dig down one side of old concrete to give it a space to crack. Then its concrete breaker out and split the lump out. If the old mix is good then normally out in two or three lumps. Most of the time its a case of staggering the new to span the old.

Contractor was removing posts from a local park.

Lifted the whole lot out with a 20 tonne digger.

An absolutly perfect 24" by 24" by 24" cube of conc on each post.

Perfectly cubical spade dug holes.

Changed times.

Old school,when the humblest labourer thought he had a trade in his hands and took a pride in his spade work.
