This spring a water main broke in our yard which belonged to a neighbor. The truck used to fix it made huge ruts in our yard. The type of dirt used to refill these ruts is the problem. We want to know what type of dirt was used to fill in these ruts on top of our lawn. Here is what we have found in the dirt so far: Green styrofoam, black vinyl screen, brown and clear broken glass, large chunks of asphalt, and many many rocks. Over the summer this dirt has hardened like a rock. Strange vegetation is growing in it. What was put on our lawn? What kind of dirt is this? We were suposed to be getting screened loam. Thanks!
