Once when we had a flooding rain, a VERY small trickle came in one of the cracks.
My experience with basements is that "small trickles" only get bigger with time.
I've had very good luck filling the cracks with a product called "Dry Lok Fast Plug". It is a hydralic cement that expands as it dries filling the crack tightly. You will need to enlarge and clean the crack before you apply it. The cement hardens quickly, so get everything ready before you mix it. I've always mixed small batches as opposed to trying to fill a large crack at once.
After the crack is sealed, paint the wals and crack area with Dry Lok paint.
