Concrete Step Crack Repair

I have a crack in the corner of the bottom step of my basement stairwell. During a large storm it sends water and sand into the bottom of the stairwell and into/on top of the drain. What is the best way to patch this?

Is there any way to get a better picture, say further back that would enlighten us as to exactly what we are looking at? Thanks.

If the hole is the only problem, you may could enlarge it slightly and apply hydraulic cement. Follow the directions on the package. It will heat up in your hands, indicating it is activating and you need to poke it in the hole and let it enlarge.

Do you recommend hydraulic cement over polyurethane concrete patch? Also, do you think backer rods are necessary to put inside the hole?

Yes. Hydraulic cement won't need a backer rod. Concrete patch is just that, a patch.

I would use backer rod and if it's horizontal, fill it with a pourable crack filler like Sakrete crack filler. If you have both vertical and horizontal gaps to fill, I would use backer rod and a polyurethane caulk like Loctite S10.
