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

What happens here

For a staggered, 2-tier retaining wall design, the topmost course of the lower retaining wall serves as the foundation for the subsequent upper tier. It is crucial to ensure that this base course is perfectly level and laser straight to provide a stable and even footing for the upper wall. Any imperfections in the base course will be amplified in the upper structure, affecting both aesthetics and structural integrity. All necessary leveling should be completed to ensure the wall is straight.

Goal: Use the top course of the lower wall as a level and straight foundation for the upper retaining wall tier
