Hi,
just clearing the front garden (or front concrete) and the drive prior to having block paving laid.
We decided to do the digging out ourselves, mainly because it is more fun than working.
However, it is raining at the moment :-(
Our block paving guy lent us a concrete breaker thingie over the weekend - like a very big SDS drill.
I wasn't making very much progress on one of the slabs, so he came back with an alternative tool.
This is a 6' steel bar; point at one end chisel shape at the other.
One end under an 8' * 4' * 5" thick concrete slab and him jumping on the other end (and he isn't a small guy) and amazingly the whole slab tilted up.
Some rubble under it to keep it slightly raised, and a few hefty welts with a sledge hammer and the concrete was broken up and heading for the skip.
I am on the difficult bit now - a continuous slab which has manhole and drains in - so I can't tip this one up. However I am still amazed at how straightforward it was to lever up a slab of concrete.
You do need a pretty solid fulrum, mind.
Cheers
Dave R
