2-tier retaining wall

What happens here

Begin by laying the first course of retaining wall blocks directly on the prepared, compacted, and level gravel base. Ensure each block is level from front to back and side to side, as well as with adjacent blocks. Use a rubber mallet to gently tap blocks into place if minor adjustments are needed. This first course is critical as it sets the alignment and stability for the entire wall. The video shows the initial courses of blocks already laid, emphasizing their importance as the foundation.

Goal: Accurately lay and level the initial course of retaining wall blocks.
