Removing concrete without damaging wall

[Marc1912]

Hi there

I need to remove this concrete from the front of my house. The concrete is abutting is the cellar wall, which is two bricks thick with lime mortar, 100 years old.

The concrete is up to 8" thick. I'm told that if we just go at the concrete with a breaker there's a big chance of damaging the house wall.

It's been suggested that we cut a line close to the wall with a concrete saw to separate the bulk of the concrete from the house wall. Then we use a breaker on the main bit of the concrete, and then remove the little bit abutting the wall by hand.

Is this approach sufficient to ensure the safety of the house wall? Obviously a world of pain awaits if it is not ...

Thanks

Cut along about 30mm out as you won't get much closer.
Break it up then.
Will then be able to cut groves in the concrete that's stuck to wall and chip off
