This is not the normal way to install field tile, trenching deeper than desired grade, and backfilling above and below with rock. No need to. Over the last several years I"ve put in at least a thousand feet with my backhoe, just eyeballing it- ok, gentle slopes, so I didn"t have to use my transit, and water still runs downhill. Even before laser technology, field tiling was done down to grade, tiles set, and just moving on. Trenches over concrete tile were filled in, plastic tile was covered, or currently, with the tile plows- just drive the installing tractor over the bump in the field to squash the evidence. Field tile comes in three types- solid, where the dinglenutz fed guy says you are going through a wetland, and it cannot be drained, and normal "perforated" (slits), and what you were referring to with a cover to keep sand out- that is "perforated, with a sock". Had over 6000 feet put in back in "83, some concrete, some plastic- covered as it went along with the trencher. Last several years it"s been another 14-16ooo feet of perf plastic with a tile plow. One pass, it is in and buried. Never seen anyone backfill with rock, unless it"s a building foundation.
