I'm having a drainage problem at my house. Negative slope up against the house where my drain and my neighbors are both emptying into my basement area. I'm not flooding but my basement floor is cracking/heaving a bit. There are 2 areas where the floor is moist where it meets the walls. In one area it's where the drainage problem is.
The other area is under a window well. I also need a retaining wall in the back yard built.
Thanks
