What happens here

After initial excavation, prepare the base for the retaining wall. This involves leveling the ground and laying a foundation of drainage aggregate. The video highlights that angular stone should be used for backfill and drainage layers, as it locks together and provides proper drainage. River rock, being rounded, does not interlock and can lead to instability and wall failure. Ensure the aggregate layer is properly compacted.

Goal: Establish a stable, well-draining base for the retaining wall.

Tools and materials

Plate Compactor Wacker Neuson — Compacting the drainage aggregate and soil in layers
Shovel — Spreading and leveling aggregate by hand
Skid Steer Bobcat T180 — Transporting and spreading drainage aggregate
Angular Drainage Aggregate — Creating a stable, well-draining base and backfill layer

before we get too deep into this is when do you need an engineered retaining wall or when do you need to engineer a retaining wall and that is any wall that's over 4T in height or any wall that has a load on it and a load can be considered two things a hill another retaining wall or actually a structure like a house. So if so those are three things but technically any any wall
