Install Downspout Drainage Pipes and Backfill

What happens here

While not explicitly shown being laid in the video, the previously dug trenches are intended for flexible corrugated drainage pipes. The presenter is shown backfilling the trenches as he progresses, covering the installed pipes. He explains that this area will eventually be backfilled completely and leveled to create a proper yard around the building, ensuring water is directed away from the foundation.

Goal: Lay drainage pipes in trenches and backfill with soil.
