Compact Trench Subsoil

What happens here

Once the trench has been excavated, use a plate compactor to thoroughly compact the subsoil at the bottom of the trench. This crucial step creates a stable and firm base for the drain pipe, which helps prevent future settling of the pipe and ensures that the intended slope for drainage is maintained over time. Operate the compactor in multiple passes to achieve uniform compaction across the entire trench length.

Goal: Create a stable and firm base for the drain pipe.
