My first house was a block structure.... I used a water repellant coating stain that was good for concrete (I used Thompsons, but there are many other brands that are good at repelling water), it is good at keeping down the water vapor that can penetrate into the core of the block, but this will not do anything if you have hydrostatic (ie underground) water coming in, nor will it help if the water is finding a hole that penetrates the house envelope...
Be sure you are very sure about where the water is entering... it may not start anywhere near where you find the water... even things like roof leaks can look to be wall failures...
