This winter the Minnesota frost heaved up 5 fence posts in my yard.
I've pulled out the 5 posts, and have found basically puddles of water and very very wet mud. I shop-vac'd out the standing water, and have let the holes air out on nice days. When it has rained I've tarped a 8x10ft area to try and get the water down hill. This is what I have been doing for the past week.
Some of the holes are still filled with 3-4inches of water, others are very wet but not filled. The holes right now are around 2ft deep, and I need to dig them to 4.5ft or so.
Should I just dig the holes with standing water? Some of the holes are so wet I'm afraid a deeper hole would just collapse. Or how can I dry them out?
