Select and Install Appropriate Retaining Wall Blocks

What happens here

Select retaining wall blocks that are solid from top to bottom, avoiding hollow blocks that are only partially filled. Solid blocks provide greater mass and strength, which are essential for structural stability, especially in gravity walls. If using blocks with pin systems, utilize plastic pins to connect the courses, creating a stronger interlock than relying solely on the block's lip. The video emphasizes that core-filling hollow blocks with aggregate is necessary to provide proper weight and connection, but solid blocks eliminate this extra step and offer superior stability.

Goal: Choose and install retaining wall blocks that maximize strength and stability.
