This is the fastest way to backfill fuel tanks and pipelines. Being able to throw the material up to 140 feet allows the equipment to place backfill around the tanks from the edge of the excavation. Material can be added in different areas as it is built up and compacted without moving the tank as it is applied. In pipeline applications, backfill materials (including flowable fill concrete) can be distributed to both sides of the pipe while the machine stays back from the edge of the trench.
