I'm looking for someone to fix the drainage problem I have in the back yard. This is different from the "bad drainage, muddy yard and want to grow grass" thread in here somewhere. I have grass, but when it rains long and hard, or when a lot of snow melts, we get a lake back there. And if it's not a lake, it's usually soft and soggy for days. The previous owners put in a french drain which might have worked way back when, but doesn't anymore.
Has anyone successfully dealt with this kind of thing? Who'd you use?
Thanks!
