The original material excavated from the trench is utilized as backfill by screening it back with ALLU screening bucket.
The savings in time and money achieved by using the screening bucket are substantial. This method makes working efficient, because there's no need to wait or arrange transportation to new material to the site. The back filling can start right after the pipe/cabel is on its place.
In addition, there are benefits for the nature when using the screening bucket. The constant job site traffic is minimized, due to less truck traffic required.
