Double Terraced Retaining wall crashes down pt2
What happens here
The presenter concludes the video by providing a detailed explanation of the benefits of using 3/4 inch clear angular rock for retaining wall backfill, contrasting it with Class 5 material. He demonstrates how the angular shape of the 3/4 inch clear rock (shown in his hand) allows the pieces to interlock tightly, preventing shifting and providing excellent stability and drainage with minimal compaction. This locking action makes the backfill incredibly secure. The video wraps up by looking forward to the next segment, which will involve completing the landscaping, installing the final capping stones on the retaining wall, and ultimately finishing the entire project. The presenter uses a small sample of the 3/4 inch clear road gravel to illustrate his point.
Goal: Understand the preferred backfill material and anticipate the final stages of the retaining wall project.
