Hi all I need to break up a section of concrete roughly 9 feet by 4 feet
from the corner of the wash area in front of my garage to get the
foundations for my house extension in.
The concrete was laid in 1974 and is roughly 12X12 feet with a drain in the
middle and diagonal expansion joints-it is approx 8 inches thick.
Is this a job for a self powered concrete breaker?.
Will cutting the slab with a Stihl saw help to make the concrete easier to
get in the skip?.
My brother in law is making dire predictions aboit the diamond blade hitting
steel reinforcing.
How deep should sawcuts be?.


Some diamond blades will cut embedded steel reinfocements, some won't.

You will have a machine in to dig the foundations, so get it to lift
this up, and the use the machine to give it a good wack, or you could
cut it into 4, so each bit fits in the skip.

If you are digging foundations by hand, a mini digger costs you 60
quid a day, and will be much more fun .........
