Which DIY Concrete Breaker?

[MCKDAVID]

if it's only 6 ft², you've already got a grinder, why not get a diamond cutting disc, and cut it into squares, then batter it with a good sized sledge, you don't need to go all the way through, just enough to get a start, even better if you've got a breaker bar, once you get a start you might be able to get under it, and lift it, into sections.

An afternoon of good honest hard graft, job done... earn that beer !!

Thanks for all the posts.

The weather looked too iffy for greenhouse building this morning so I went to Screwfix first thing and bought the £150 Titan. It was very effective on the parts of the slab that were 4 or 5 inches deep, but was hard work on the 7 inch bits. Managed the 8 foot square slab before lunchtime. I wish I had it last weekend when any amount of leverage wouldn't move some old concrete steps so I left them be and spent an afternoon making a fence post hole through them with the SDS chisel.

Didn't want to use a sledge hammer as there are some cars parked on the other side of the fence from the slab.

Going to need another skip!

Some of it is down to technique....we cast a 350mm thick concrete slab 8m x 6m in a shared bit of the yard to build a tower on.
After much nagging we had to break it out - it had been down a while so was hard as hell. I started on it with a heavy duty Bosch breaker, slow work.
One of the lads had a go (an ex groundworker) and had it smashed up in no time.

Ive used those titan mini breakers and the chinese drill type, and theyre both not very brilliant at the task but acceptable on thinner stuff like malcom has found. Ive also hired a breaker from my local place that I had to sign a declaration it wouldnt be used near public infrastructure as it had a large hammer action, and that went through years old hard as nails concrete like it was butter, and I used them quite a bit years back doing groundworks for some building contractors as a labourer. But... mostly now I just get the digger and pick the edges up with the bucket using the back edge as a sort of cam action and the craw to pick it up, and that is REALLY effective, and my buckets dont seem to have suffered from it. Bonus, its a damn sight easier sitting in a cab moving some sticks than getting whitefinger and a sore back and we dont have to hire the digger
