What happens here
Once the wall has reached its final height and is properly backfilled, install the capstones on the top course of blocks. These caps provide a finished look and help protect the wall from erosion and weather. Place each capstone firmly on top of the blocks, ensuring they are level and aligned. For a permanent installation, use a construction adhesive (like landscape block adhesive or concrete adhesive) between the capstones and the course below.
Goal: Provide a finished and protective top layer for the retaining wall.
