We have had a shit load of rain this weekend. Seems a fair bit of it ended up in my basement (well, at least the front room of the basement. I've been working on it the last couple of weeks. Tore down the sheet rock and trying to correct 30+ years of water damage. I sealed up the masonry pretty good, and it seems to have held in all but one spot (which will get a third coat of sealer) but that really was no match for the river of water that was flowing through the window frame and onto the floor.
I think the plan now is to raise the ground next to the house and then gently slope it towards the street in order to keep the water from collecting in the corner of the house. Will probably take most of the summer to complete.
