I've been asked by my mother inlaw to remove a concrete foundation which
had a wall on it at some stage. The foundation is 10 feet long and 10
inches deep and also 10 inches thick. I've never used a jack hammer
before so can someone please tell me how long I should allow for
breaking up and removing (not disposing of) the concrete. Is it a very
demanding job- as I have an occassional bad back?!
Thanks for any help

It really depends on the quality of the concrete. Hopefully, since it was
only wall footings it won't be too hard, and if this is the case an easy
half day should see it bagged up.
However, if you've got back problems, couldn't you tell your mother-in
-law to get it done by a pro? It's the sort of thing landscape gardeners
do plenty of.

I've just taken up a floor screed about 12ft sq using a hired electric
breaker and it took about half a day.
BUT it was really tough concrete and only 5 inches deep
Hard work but MUCH easier than doing in without the breaker

It sounds a strange thickness for good concrete. Is it just lime
If you have a decent jack hammer and compressor the trick is to work
near the edge of the concrete. Work say 2 foot from one side and
nibble through it in four inch bites that should leave you about 5 x
18" or so blocks to dispose of. Or just keep taking 3 or 4 inches off
the end until you have a pile of rubble.
There should be plenty of takers for a few quid at your local pub if
you need an hand. The 10 inch thickness will take forever with a
sledge hammer if it's good stuff and your back is bad. If you can
undermine it though....
I help my bro-in-law dig up the concrete base of a compost heap a couple of
weeks ago. It was about 3'x9'x8" reinforced concrete (for a compost heap!?)
and had 8 concrete posts stuck in it too. We used a sledgehammer and pick
axe and it took 3 of us a good few hours to get rid of it, and my hands took
about a week to recover! (it really got to the muscles around the thumbs)
Hire a hydraulic powered breaker, very easy to use and you will be done in
half a day, then all you have to do is dig out the lumps,
If you hire an electric you will need a big Kango machine as the Hilti TE905
is not quite tough enough.
