How to plug unwanted and leaking conduit?


I have an old conduit going through my concrete foundation, about 1 foot underground. It's roughly 1 inch diameter, some sort of poly pipe. It used to have a couple of copper lines running to an underground oil tank. The oil tank was removed a long time ago, but the lines were just cut and bent over. Water has been leaking in through the conduit (not around it) every time we get a big rain. Today I dug down to the conduit to look into plugging it from the outside. I've removed the copper lines and now have a 1" conduit to nowhere in my foundation that I need to plug. What is the best way to plug this thing? The conduit is about 14" long going through a 12" wall. A local box hardware store guy said I need to pull out the conduit and plug the hole with "Quikrete Hydraulic Water Stop" and to even burn out the old conduit if I had to. Then I talked with another guy at the same store, and he said that I probably won't be able to get the conduit out, and that I should fill it up with an expanding foam, and seal the outside end with some sort of caulking. I thought I would just buy some sort of two part epoxy and fill it up, but I guess thats the wrong idea? I've enclosed a picture of the inside and the outside. I live in New Hampshire USA, so it does get cold here in the winter if that makes a difference... ?

Cut off flush, or use a cap & cement on there. If have to use a chisel to make a recessed spot to take the hydro when you pack it, you will have to. Remember, that if you use a torch, it will be worst, than either capping with a cap & filling with Hydro Cement.

That's what I was thinking, fill it with foam, let it cure, then fill each side with silicon.

If you could put a cap over it too, that would make it even better.

You can buy ABS pipe caps at any building center.

On the outside, clean the ABS off, and then glue the ABS cap in place.

Simple and cheap!

That's what I'd do!

I would still fill it with spray foam. it will ensure that it's sealed and insulate it too so you don't have to worry about condensation.
