There's various possibilities. You can get foundation specialists to evaluate, and possibly bid on work. A guy told me you can lay down a moisture barrier, basically plastic sheeting on top of the soil in my crawlspace. Since you have a basement, you may not have a crawlspace. If I dig down in my soil (also heavy with lots of clay) I will come to water less than 2 feet down. I dug a trench in my backyard in early March, about 2 feet deep in order to plant tomatoes. Leaving it overnight, I find next day that there was around 3 inches of water in the bottom of the trench.
A foundation guy told me it's possible to install a french drain after doing a foundation job if it's determined it's necessary. He didn't recommend putting in a french drain at the time of a foundation rebuild. Other guys have different ideas. One guy wants to put in a sump pump. When you talk to enough of these guys (at least with my house) you soon realize that they all have different ideas.
