What happens here
The camera pans to show workers actively digging out a substantial trench. This excavation is for the foundation of a large retaining wall, which is essential because the patio grade is situated much lower than the adjacent soil level, which climbs steeply up towards the house. The retaining wall is needed to support the significant amount of soil and prevent erosion, creating usable flat areas on the sloped lot. The presenter explicitly points out the steepness and the necessity of the wall.
Goal: Illustrate the intensive excavation required for the 'Big ol' Bertha walls' due to steep grading.
Tools and materials
