Layered Backfilling and Compaction Technique — Backfill Around Risers
Part of project
Septic System Maintenance · Step 8 of 10
In this video
Begin the backfilling process by adding soil around the septic tank and into the trench in approximately 12-inch layers. After each 12-inch layer of soil is added, it must be thoroughly compacted. The video demonstrates the use of a mechanical Wacker compactor for this task, but a manual soil compactor, which can be purchased from hardware stores like Home Depot, can also be used. This meticulous process ensures there are no large settling pockets in the future, which could cause structural damage to the tank or pipes. This step focuses on the technique and reasoning, not the full execution.
