Install and Compact Foundation Stone

What happens here

The final step in this part involves adding a layer of foundation stone (typically crushed gravel or aggregate) into the trench, over the geotextile fabric. This stone layer provides a level, permeable, and load-bearing base for the retaining wall blocks. Once spread and leveled with a rake and shovel, this stone must also be thoroughly compacted using a mechanical compactor to ensure maximum density and stability, similar to the subgrade compaction. Use a level to ensure the stone layer is perfectly flat.

Goal: Create a solid, compacted, and free-draining stone base for the wall blocks.
