old pipe hole to fill in, block foundation

Hi,
We are doing a new patio and noticed an old abandoned pipe going into the block foundation when prepping. The pipe is being removed and I want to prevent leaks in the basement. What is the best way to repair the hole, preferably from the outside and are the materials readily available?

Thanks.

Your local lumber yard, hard ware or big box stores should have a quick patch drying concrete and then tar.\ over it after it dries.

Hydraulic cement - it cures quickly, and expands slightly to make a good seal. I'll say it again...it cures quickly so don't dawdle.

Thanks

Thanks guys. I read Hydrolic cement deteriorates quickly if below grade....cannot always believe everything you read.

Fill the hole with the cement entirely or another medium and then the cement over it?

Thanks!
