Wet basement...please help

We had about 5" of rain in 2-1/2 days and the hydrostatic pressure caused a wet basement. My plan of action is to re-slope the soil around the foundation and seal leaky concrete. The soil slopes away from the house except within a few feet of the house. I just purchased the house in November 2007 and this was my first wet basement. The house was built in 1900. It has a concrete block foundation. The previous owner used Dryloc. I prefer to direct the water away. Until now the basement has been nice and dry.

1. I'd like to regrade the slope near the house and cover it with plastic followed by cedar mulch. I plan to take the palstic up the wall a few inches and away from the house 3 feet. It can flow to the road from there.
2. I am thinking about using hydraulic cement between the walkway and brick exterior of the house (just a 1" bead to seal the crack). Or do you think I could just use masonry sealant?

I need tips on techniques, materials, and tools. You can not give me too many details.

Picture#1 - Notice negative slope
Picture#2 - Low spot in from of the door and crack that may be allowing water into the ground.
Picture#3 - Negative slope beside side steps and side of the house.
Picture#4 - I think I should built up the soil beside the deck and direct the water away from the house.

I do not have thin skin so bring it on. The more the better.

changing grade is a good idea but

looks like your house bricks is so low already.... because normally I see concrete then bricks and the concrete should above the ground a bit...that is in mind house....

I don't know if you just add soil on the brick walls ... because brick is not water proofing....

well I am no expert... but may be your case is not so simple as just adding some soil to change the grade....

you may need to add those underground gravels/pipes/...etc. to direct water from under the ground rather than at the surface by the soil.... as I heard soil should not go above brick walls....

So I would think for those short distance surround your house which has negative grade, you need to replace them with gravel and put pipe system below it, and have the pipe sytem direct output to the proper grade outside area the pipe system is going to have horizontal and vertical segments... the horizontal segments is for correcting water... the vertical segments is direct it to outside proper grade area....

and I kind of think of this myself... and have no experience/knowledge or whatsoever... the only experience I have is digging my backyard for interlock and because of that learned somthing related to grade....

Thanks for the reply. Maybe I will need to cover the brick with a foundation coating before regarding the soil? Does anyone know if that will help?
