Repair a Big hole on my Basement wall
 
Hi, I replaced my old boiler and water heater tank with a new combi boiler, so right now I have a big hole on my basement wall. This hole was for the boiler and tank vent and this vent is on the chimney. I would like to know what is the easy way to repair this concrete wall. I was thinking to fill it first with one of those filling foams and then I will put some concrete on top of that. I was wonder if this is ok since the hole is on the chimney vent. Thanks

A picture (or two) is worth a thousand words.

I attached a picture. I put the window on the picture for size reference.

Maybe after I use the foam I can stick couple of metal sticks so the concrete have something to hold.

I'd fill with brick or block using mortar and skim/stucco over it all after filled, might have to let brick/block dry some before skimming

When you say dry, what do you mean?

let the mortar dry/set up in the filler some before skimming over it with more mortar.

I moved an 8" round duct that went from our basement into the crawl space to a different spot and the old hole was patched just as you're thinking. I filled the void with the triple expanding foam and left it to cure. Then a put a dozen or so long drywall screws in the foam and mortared it over. Its been 20 years ago and it still looks great.

Try what the PoleCat has done 20 years ago and might be it repair the hole of wall in better way.

I already fill the hole with bricks and mortar. It look good. Thanks for all the replies

Final result. Is not beautiful, but this wall is going to be frame and Sheetrock.

Thanks for posting. It's nice to see someone take the time to share a picture of the end result. It's a bit more gratifying to those who took the time to answer questions.
