What happens here

Once the subsoil is excavated to the desired depth, use a plate compactor, powered by a Honda engine, to thoroughly compact the exposed soil. This step is critical to prevent future settling of the stairs. The material should be compacted in multiple lifts, typically 4 inches at a time, even if the total depth is greater. This ensures uniform compaction and eliminates soft spots that could lead to uneven settlement later on.

Goal: Achieve a firm and stable subgrade to prevent future stair settlement.
