Small details, big difference.
What happens here
This step demonstrates the technique of notching capstones to ensure a tight, seamless fit where a retaining wall capstone meets a lower course of blocks, particularly at steps or corners. The video highlights how a portion of the capstone is precisely cut out ("notched") to allow it to "hug" the adjacent lower block. This meticulous cutting eliminates gaps, providing a clean and professional appearance for the retaining wall, as indicated by the narrator's praise for "beautiful craftsmanship."
Goal: Create a precise, interlocking fit between capstones and lower retaining wall blocks.
