There's two soft spots just beyond the wetland boundary on my driveway (swamp road). Yesterday I put 15yds of tailings in the first one, and today I unearthed the demon beneath the second. Even with that much base, the first was unable to support the tractor without massive rutting.
As I finished up for the day, I dug a trench across the whole width of the soft spot in the first. It's 19' wide and 18" to the water line. Hopefully the trench lowers the water level in the surrounding soil so I can at least not sink walking around the worksite. The question remains - what to put in the hole?
I don't know how far uphill from these furrows (that's the source of water) I'll be able to dig without a mini-ex.
