OK, here is another one. ( I don't remember if it was asked before,if it was just stop me.)
You have a parking lot being torn up and repaved. You have to run lines across the parking lot before they can pave. They try to dig down the proper 24" depth, but only get 6" then there is all rock in the way. Can you just pour 2" of concrete around the pipe and then pave the parking lot?
What if it is Rigid pipe? Non metallic Rigid?
