Assemble Interlocking Blocks and Fill Voids

What happens here

Next, the narrator demonstrates the physical assembly of the 'Block-Bridge' system. Specialized clips are shown being inserted into the hollow cores of the main retaining wall blocks. These clips then extend backward to engage with a second set of concrete masonry units (CMUs) that act as anchor blocks, placed directly behind the main wall. The void spaces within these CMUs and the area between the front and anchor blocks are designed to be filled with rock or other appropriate fill material, providing substantial weight and structural integrity to the wall. This interlocking and filling process is what creates a stable gravity wall without the need for extensive geogrid layers.

Goal: Physically connect the retaining wall blocks using clips and fill internal voids to create a stable structure.
