Concrete Internal Wall - Now with picture

[fattony]

Yes you read that right, concrete internal walls, 2 of them which I wish to remove, this is in an outbuilding single story with a timber / felt roof.

Would a 9inch angle grinder with a diamopnd blade cut throiugh this or am I looking at something bit heavy duty?

Concrete blocks? If so then a hammer and chisel. Will be hard getting the first couple out but after that plain sailing with a sledgie.

If its a cast reinforced concrete wall then 9" grinder bare minimum. Preferably a 12" Makita or Stihl saw, or you can even get a concrete chainsaw. Noisy, messy and bad to know!

This all assumes that the wall isn't supporting. You could also try a heavy duty breaker.

In any case, steel toes, hat, goggles a neccesity!

Thanks for the advise, I believe its reinforced concrete, steel toe caps a must with goggles and mask!

I have uploaded a picture of what I plan to do, I have had a friend round who has done some building jobs and does not see it being a problem to take these walls out, but he is not a structual engineer, the only load these walls are currenty surrporting is the aspestos roof which is being removed and Im going to fit a new felt roof.

Firstly do you mean this type of saw http://www.amazon.com/Makita-Concrete-Cut-Off-Saw-DPC6410/dp/B000R039HE

if you take out those walls, will the side fall over?

Maybe leave some piers.

 

[fattony]

leaving some piers, do you mean leave about 4 inches either side?

something like that
