Be very careful with any type of plastic pipe passing under a foundation. The loads on the pipe from the foundation can cause deflection or collapse of the pipe depending on conditions.
If you have to pass under a foundation with plastic it is not uncommon and often recommended to install a ductile or some sort of steel carrier pipe below and a few feet beyond the foundation for the plastic to run in. You can get the structural engineer to provide loading information and then make a decision on depth of cover or other provisions needed to run below any significant structural element. Craig L.

I know that's all I've ever seen, but can C900 PVC pipe be used? I've browsed through the International Plumbing Code and didn't find any discussions about this situation.
