Not sure if this is the right forum but... One of my customers had a water line leak from the road to his house. Had it dug up and replaced. Now there is a pile about 18" high x 6' wide and 40' long. It has big lumps of hard clay. He asked me if I could do something with this. I have not a clue. Does anyone have any suggestions as to how to get it packed back down sooner instead of waiting for nature. It's amazing how much the dirt puffs up when dug up. The man asked to rot-till it and he would have a truck load of water dumped on it. I don't think that will help much. Will it? I suggested maybe someone with a hiway grade roller would pack it down. Any suggestions?
