Demolish Old Wall & Prepare Retaining Wall Base

What happens here

A significant part of the project involves replacing an old, failing retaining wall. The video explicitly mentions removing a 'dumpy wall that was falling over' and installing a new one. After the old wall is demolished (as mentioned in Step 1) and the area excavated, a stable base is critical for the new retaining wall. This involves laying a compacted layer of granular material, such as crushed gravel or road base, to create a level and solid foundation. Geotextile fabric might be placed on the excavated soil before the base material to prevent soil migration and improve stability. Proper drainage behind the wall is also considered at this stage.

Goal: Remove the old, unstable retaining wall and establish a solid, level foundation for the new wall.
