That is not going to keep water from seeping under the walls into the house. It will slow the water down some from what runs down the hill, but in a heavy rain, the concrete that is against the house is going to let water under the wall.
Also, the area that you showed in your first round of pics where you say they are going to be pouring a solid patio between the rooms of the house....you may want to reconsider. If it is not excavated out first and made considerably lower than the floors inside, you will have a major water problem inside. The pic and area I am talking about is the one that I stated that you needed the dirt lower than the band board.
I didn't find where you said that the house was a foreclosure or if the previous owners listed it with a Realtor to sell, but you may be able to go back on someone for "failure to disclose" that the house had previous problems. Be sure to talk with your lawyer about that.
Forget about the "disclosure". I went back and found the pic I was talking about and saw where you said the bank was fixing things on their dime. I don't know whether you could go back on the bank or not to remedy your problems. Again that would be up to your lawyer as to whether you could or not.
I have a feeling that before you get things fixed, you are going to run into some major landscaping issues to get the ground lower than what the slab is. And if you are getting water in under the walls, you're also going to have to deal with mold issues along with it.
Good luck. You are going to need it. Be sure to keep us posted.
