Excavate Trench, Compact Base, and Lay Geotextile

What happens here

After clearing the site, a deep trench must be excavated where the base of the retaining wall will sit. This trench provides a stable foundation for the initial layer of boulders. Once the trench is dug, use a vibratory tamper (like the Wacker Neuson BS50-4 shown) to compact the soil at the bottom of the trench. This ensures a solid, unmoving base for the wall. Lay down a layer of heavy-duty geotextile fabric along the bottom and up the sides of the newly dug trench. This fabric helps to separate the soil from the base material and provides additional soil stabilization, preventing erosion and retaining wall settlement.

Goal: Create a stable, reinforced base for the retaining wall.
