I have a lad making up a steel post and rail fence in sections which will be used to divide a concrete yard.
The steel posts will be buried about 15 inches below floor level into the concrete and re-concreted around.
While the guy making up the steel will do the welding and fitting of the final sections I have to get the holes dug out for him to bury the posts
So I have seven holes to break into an existing concrete yard/ floor. I am not sure of the depth of the concrete as it was pored before my time here. I would think the depth is hardly more than 75 - 100mm
The holes will need to be about 15 inches square. I would like to keep the holes as neat as possible.
I am wondering on the best way to tackle this. I'll have to hire the gear to do it from the local plant hire
Would a con saw to cut the concrete and then a kango hammer do the job?
Would I get a 15" X 15" hole cut easily with a con saw?
Is there a better way?
