Breaking up is hard to do - Concrete fence post footings

[Tetrarch]

I managed, after a lot of sweat and swearing to get three concrete posts out of the ground. They were each embedded into huge lumps of concrete with hard core about 50 years or so ago. I have a trailer, but despite the fact that they do "roll", getting these gigantic balls of concrete in is proving too much for me. A ramp and a winch might work, but they'd also be difficult to remove at the other end. Each probably weighs slightly in excess of 100Kg

Are here any recommendations for cracking these monsters into smaller chunks? Even in half would work. I have tried hitting them with a large chisel and sledgehammer to no avail.

PS I have already managed to break off the concrete posts so these are just round(ish) lumps

SDS drill or breaker, as you would break up any other concrete.

as Freddie says: you need a breaker.

use a point chisel not flat chisel.

unless you use a big powerful breaker, dont try and split in half, nibble away at it

a small breaker would just get the chisel stuck or wouldnt go in

I used one of these to clean off concrete from post while still in the ground, very easy.

You could hire a breaker for a day.

I recengly broke up some stuff using a flat chisel attachment in my heavy SDS+ drill. Is is poor quality but was very cheap and came with a heap of attachments. People sneer at it, but I originally bought it before some heavy work, and the Screwfix guarantee meant that if it had broken before I finished, they would have exchanged it or possibly refunded me. I bought an extra big chisel. The huge weight is not a problem when working downwards.

It has paid for itself several times over.

I don't have the use to justify a good one.

Don't forget your ear defenders.

Ear defenders, I said.

EAR DEFENDERS! WHAT'S THE MATTER, ARE YOU....


Oh, sorry.

People sneer at it

But they wouldn't dream of nicking it; handy for site stuff, because the screwfix guarantee only covers thing that you can walk back into store with

Side note, my workzone equivalent of that drill has done sterling service over the last 8 years, and still going.. "Buy cheap, replace it with something up the scale if it packs up.." usually works for me

Are here any recommendations for cracking these monsters into smaller chunks?

I'd get a stihl saw out and cut a slot in it to pound a chisel into, but if you don't have a stihl saw it does rather put paid to that approach; they can be hired fairly economically

How about burying them in the garden?

Considering these are about 60cm diameter then I'd have to dig a hole that would make my neigbours curtains twitch like mad!

This is a great long-term solution, maybe a little too long....

Try dynamite

 

[robinbanks]

Think you'll struggle getting it transported . Maybe TNT will deliver it..

 

[mitch66]

Get a mate to lift them with you?

 

[mitch66]

Assuming you've guessed the weight right. Could be heavier?
