PART 3: How to build a 2-tier retaining wall. #hardscape #retainingwall #howto

This video conceptually explains key elements in constructing a 2-tier retaining wall, specifically focusing on the continuous process of backfilling with clean stone, integrating geogrid for soil reinforcement, and establishing the foundation for the upper tier using the top course of the lower wall. It also touches on drainage considerations for the upper tier.
