Filling In Conduit

matt151617

I have an old post light in the front yard that was backed into by a delivery truck. Due to the extreme cold it snapped and broke the light. I'm left with a 2" hole that's wide open and I can see open conduit in the hole leading to the house.

What can I fill this in with to stop water from getting into the conduit and getting in the house? The conduit is set back enough that I'd have to fill in the hole itself. I plan on just removing the surrounding cement in the spring and growing grass over it.

Put a cork in it.

Silicon and disconnect the wires

I can't get to the conduit opening itself, only the large hole where the post was. I was thinking spray foam but I'm not sure of it's water resistance.

Spray foam will work. You will have to dig down to pull out the old concrete and cut the conduit anyways, when it comes time to fix. I would just put a garbage can over it, or just leave. You can always use a shop vac to pull the water out, which if you just cap with spray foam by putting a small plug into the conduit, you will be safe.
