It’s a good idea to check for cracks along the basement walls and floor at least twice per year since cement and cement blocks will break down over time.

If you see something, head to the Home Depot and buy some hydraulic cement, then follow the instructions and apply it. It will expand as it cures and fills any cracks. Apply a coat of sealant after that (although don’t apply a sealant over a wall that has been painted – strip off the paint first).

Keeping your basement this way though is an ongoing issue and you will have to stay on it because water is pounding away at your basement walls relentlessly.
