We are laying about 50 ft of PVC (1'' conduit) in a trench. We are going to sift the material that we took out and put it back around the conduit.
Question is what is the minimum thickness should the "sand" cover all around the conduit? Does the "sand" need to be compacted? If yes at what compaction percentage? Wet compaction or dry compaction?
