Jerry,

So from your description, a relieving arch will never be added after the footing is already there, it's got to be engineered into the system when it's built.


How'bout this then: When a basement is built with a poured cement wall, and is core drilled, does that still need a sleeve?

And furthermore, I have a question about the material of said sleeve. I know its supposed to be two pipe sizes larger than the pipe itself, so if I have to run 1/2" pex through a wall, how much protection is that 1" pex really going to offer?
