First thing I would look into is how water is getting into those cracks in the first place. Check your gutters and make sure they’re cleaned out and at appropriate angles, and check the downspouts. Water should be draining away from your home, not into it. You might need to put up some sort of awning or tarp, and fix the angles of those pavers/concrete. If there’s water flowing into the foundation then it’s going to be a reoccurring problem.
