Ran a water supply to the garage from the outside tap. Within minutes I hit 1.5ft of concrete between me and the tap, damn I thought. Then I noticed some old electric ducting not far from where I needed to run the pipe. It's not as deep as if have liked, and I'll have to insulate the pipes, but it'll do, probably my best get out of jail free card ever
I take it the black duct was already exposed by the slab edge? As I was wondering how else you got the blue pipe there without lifting the slab. That saved you a heap of work then by the looks of it.
