Reinforced Concrete Breaking

[Tofa83]

Hi

I have just took down a concrete coal house, consisting of 5 sides (inc top) of reinforced concrete slabs which were bolted together

I will be ordering a rubble\hardcore only skip shortly and would like to put them in once the rebar is out

Any advise on breaking them up?

Will a sledgehammer do if they are unsupported (stone under one end so its elevated and just wail on it )

Thanks

I broke up large slab walls of a precast concrete garage (of 1940/50's design) using one of these:

I gave up using a sledge hammer, just took took long - I think the Rebar was doing its job too well - rebar was a pain to 'unthread' and break loose, took a few hours to break up once i got going.

Thanks, Got an SDS drill
Might give that a try to loosen it up

You could stitch drill before using hammer.

Yes I should have said SDS, I used the SDS chisel bit that came with it, worked fine.

Your chisel bit will get blunt, use a grind wheel on a drill to re-sharpen it.

just belt them with a lump hammer or sledge.
once you can lift them pop in wheel barrow and skip it.

Are the sections still intact? Stick them on gumtree....
