pvc pipe and footing


The reasons that I spec schedule 40 galvanized steel pipe for sleeves are:

1. Steel is close to concrete in its rate of response to thermal change, the grout used to set a steel sleeve will not separate from the masonry like it will when a plastic sleeve is used.

2. Will schedule 40 Galvanized steel rust out? I guess it could in about 356.7 years. I wont be around to see it.

3. Steel does not melt in the event of fire, producing toxic gasses. PVC does.

From a stuctural standpoint, the concrete footing isn't going to care if you sleeve or not. Generally, you can take the entire top half of the footing without causing undo weakness to the footing itself. There's hundred's of thousands of basements here with 4" outside diameter cross bleeders every 8-15', with no issues at all..........

I would like you to retract # 3 in regards to pvc pipe passing through said sleeve.
