I have a vertical crack in a poured basement wall. the source of the pressure causing the crack has been identified and taken care of, no movement over a 5 year period. I have used a SDS hammerdrill wwith a chisel bit to open the groove so it is now averaging 1-1.5 inches in depth and the material will have enough surface area to get good adhesion. It is a wall between the basement and attached garage, so it doesn’t see much water ( if at all) and has not leaked once. the other side was dug out and the area re-tarred before repouring the garage floor.
I am thinking of using hydraulic cement as it expands slightly wjen setting/curing and should result in a tight joint. Appearance is not a probem, that portion of the basement is just used for storage anyhow.
What’s the best repair material to use?
Thanks in advance for the help.

Hydraulic cement is what I'd use, for the reason you cited--it expands as it cures.
Thanks for confirming my thoughts Dano. Just wanted to check with others here before I chose one method and then found out there was a better /easier way . (Who says an old dog can learn new tricks?)
For a really good bond, power (or hand) wire brush some of the cement paste onto the sides of the crack before filling.
I agree that is worth seeing if there is something better or easier. Also good to get confirmation before going ahead.
If it's not getting any larger and not leaking water, why spend any more time and resources on it?
why spend any more time and resources on it? because he has already chipped it to an inch wide , and DW is probably complaining about all the spiders that are going to crawl into the house.Whenever you are asked if you can do a job, tell'em "Certainly, I can!" Then get busy and find out how to do it. T. Roosevelt
Before hogging it out it was about 1/4" to 3/8" wide already and had some crumbling edges, so it really needed to be repaired so it would look presentable.
