In preparation for the garage slab and basement floor, tailings (sand) and pea gravel were put down. For the tailings, in the basement, we used "Stone Shooter." 40 yards of tailings were thrown into the basement using this truck and conveyor belt, and only needed minimal leveling. The driver controlled everything, including moving the truck around, with a control box around his waist. The largest remote control vehicle I've seen. Joe also received permission to backfill the drain field. The system was pressure tested, and covered.
