I’m prepping some footings for a new porch for my house and I’ve come across two pipes that run directly through one of the footings. I was expecting to run into the smaller water pipe but the gas line took me by surprise (I know I didn’t call before I dug)
The footing will be 12x24x60 (concrete).
Do I need to have these pipes moved to go around the footing or can I have them run through the footing with maybe a schedule 40 inserted around them (cutting the protective pipe tube in half and then tying it back together with some butterfly clamps).
Would that pass inspection? Atlanta GA.
Any thoughts would be greatly appreciated.

If you surround the pipes with sleeves before the pour, it would meet code where I am.
I had to do something similar with a/c lines through the stem walls of an addition. I cut a piece of 4" PVC in half lengthwise, wrapped the lines in a layer of cardboard, taped the two halfs of the PVC pipe around that, another layer of cardboard, and sealed to holes in the forms with spray foam. Pour away. When the stem wall cured, I popped out the cardboard and PVC. Voila. Lines through the concrete and they can still be replaced or serviced and movement of the wall won't break the lines.

Why did you bother to remove teh PVC?

The hole for the lines was below grade so I had to seal it. I didn't see the split PVC as allowing a good seal. The cardboard wrap left just enough space from the concrete around it that it was easy enough to get the PVC out.

thanks for the tips-I appreciate it--okay off to watch LOST.cjeTake what you want, leave the rest
All you need to do is protect the pipe from the concrete.
Pipe would work, but I think a foam rubber type insulation would be easier.
Like rubitex or armaflex.
will allow for settling without puting strain on pipe.

EWWWWWWW red clay.. no fun to dig...
Oh yea, the original question... encasing the pipes before the pour should work.. When in doubt check with the local codes department..
Measure once > cut once > get board stretcher....
around here, gas can not go under concrete, through slab or footing. must go through wall
What about sidewalks & driveways?Do you look to the government for an entitlement, or to GOD for empowerment. BDW
I think their idea is, if you get a leak , gas wont pocket under a house. since gas is heavier than air

I think only propane is heavier than air.
Piped natural gas is mostly Methane, which is lighter than air.
Nope. The idea is that if there is a gas leak anywhere outside the house, it'll follow the piping to the house and enter there, where it can build up. If you take it up above ground and then through a wall, the gas escapes into the air before getting to the house.
