Got a job next week and guy says a foot down it's bedrock, anyone had experience with bcos etc and what they want depth wise. They don't want you to breaker it out just to pour concrete do they?
Normally got miles of clay or sand here

I was on a site in Liverpool where the ground lads were channeling through bedrock so that the strip foundation could be poured on the orders of the BCO, complete lunacy

Tony dont want to intimidate them hehe 
Might take the 8 toner then if we have to go that route, bigger= better when hammering.
I'm going to run it by our structural engineer see if we can raft it instead. This guys architect has thought it usually bs about assumed ground condition being perfect.
