I am having this mental debate with myself. I have about 1000ft of trenching to do for various pipes, from sewer, water service, electric conduits, etc, etc max depth probably will not exceed 3ft. The issue is I have several trenches crossing each other, and will need to get under 2 structures a bit for water and sewer.
I have a LOT of experience cleaning up trencher trenches with a shovel, especially intersections. I also have noticed trenchers usually don't leave a firm trench bed unless we run slow.....
I have to cross a driveway where there will be heavy traffic loads at times and I am still trying to solve the riddle of depth and backfill plan to ensure all piping survives the traffic. I had considered calling for a little CLSM to go around the pipes but question whether a course sand could handle this just as good?
