I have a serious problem that I dont know how to fix Ok so here is what is happening: I just got done with having my house remodeled. During the remodel, the contractor ran over part of the lawn with his machinery for 9 month, leaving it compacted down. So when it came time replace my yard he brought in black dirt to make it all even and fill in any areas that were compacted and then re-graded the yard, he then put the sod down and all was good. I had a boggy yard for a month and everything is fine or is getting better as the days go on. But I have one section of my yard that is a high traffic section that is all mud. I had them look for a cracked irrigation line and they couldnt find any. His landscaper put down about 9 inches of dirt to make up for the low spot they made. But now I cant even walk on the section without messing the sod up. The sod has been installed for almost two months and I cant mow it because its too wet. I cant walk on it because we have had a lot of rain in Minnesota and the water is not draining out. I cant put in any kind of drainage really because I live on the lake and we cant dig down too far. So the grade is almost nothing. I have drain tile in a few spots so the water can drain into the lake but its not possible to install one at this location. So my question is, what can I do to turn this mud pit into solid ground? I have heard of mixing sand and petemoss in there but I have heard that if you put too much in then it will just make matters worse. I was thinking of mixing in some wood chips too. Should I just remove all the dirt and till up the hard packed area to see if I can get it to drain better and then put the dirt back in or just mix some things into the dirt?
